Christendom continues to be an embarrassment to God and Christ.

 Moscow patriarch: Russian war dead have their sins forgiven

The patriarch of the Russian Orthodox Church says Russian soldiers who die in the line of duty in Ukraine have all of their sins forgiven


ByPETER SMITH Associated Press

September 27, 2022, 3:53 PM


 soldiers who die in the line of duty in Ukraine have all of their sins forgiven, the patriarch of the Russian Orthodox Church proclaimed in a sermon, comparing their sacrificial death to that of Jesus.


The assertion, made on Sunday, ratchets up Moscow Patriarch Kirill's already staunch support for Russia's war on Ukraine since its beginning in February.


Kirill has characterized the war as part of a larger metaphysical struggle against an encroaching liberal West, which he depicts as demanding gay pride parades. He has echoed Russian President Vladimir Putin’s depiction of Ukraine as spiritually and politically tied to Russia through their common medieval roots.


But Kirill's latest words raise the rhetorical stakes at a time when Russia has begun mobilizing reservists and has taken steps to annex parts of eastern Ukraine in the wake of military losses to Ukrainian forces.


“If someone, driven by a sense of duty, the need to fulfill an oath, remains true to his calling and dies in the line of military duty, then he undoubtedly commits an act that is tantamount to a sacrifice,” Kirill said in the sermon

  He sacrifices himself for others," Kirill said. "And therefore we believe that this sacrifice washes away all the sins that a person has committed.”


He compared the sacrifice to that of Jesus on the cross.


His words came even as thousands of Russians have sought to avoid the chance for such martyrdom — leaving the country by land and air rather than being swept up in the mobilization.


Critics of the war were appalled by Kirill's valorization of soldiers fighting in what much of the West has denounced as a war of aggression, accompanied by alleged human rights abuses.


Kirill replaced the Christian concept of martyrdom “with the idea of religious terrorism,” said the Rev. Cyril Hovorun, an Orthodox priest, native of Ukraine and professor of ecclesiology, international relations and ecumenism at University College Stockholm.Martyrs sacrifice their own lives, but religiously motivated terrorists ”sacrifice their lives and the lives of others," said Hovorun, founder of Orthodox Against War, a project launched after the start of the war. “And the (Russian Orthodox Church) is trying to find an excuse for this activity.”


The patriarch is speaking to an audience of one, Hovorun said.


“I don’t know whom can he convince, because the Russians are listening to him less and less,” Hovorun said. “However, I think the main addressee of Kirill’s messages is Putin. Kirill, through these messages, communicates to Putin: I am with you."


Kirill repeatedly described the war as “fratricidal" and prayed that it not destroy “the single spiritual space of Holy Russia."


But his unswerving support for the war has already helped precipitate a historic rupture in that space. Eastern Orthodox Christianity is the majority religion in both countries. The Urainian Orthodox Church — which had remained loyal to the Moscow Patriarchate until this year, even when other Orthodox in Ukraine had broken away — declared its independence in May. By then, many priests and bishops had ceased commemorating Kirill in their public worship, a ritually potent snub.

Origin of life has all the time in the world?

Origin of Life: Saved by Time? 

Walter Bradley

Casey Luskin

 Editor’s note: We are delighted to present a series by Walter Bradley and Casey Luskin on the question, “Did Life First Arise by Purely Natural Means?” This is the fifth entry in the series, a modified excerpt from the recent book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos. Find the full series so far here. 

Many materialists believe that the severe unlikelihood of the series of events required for the origin of life is not a serious problem because there is essentially unlimited time for these events to occur. George Wald expressed this sentiment in 1954, writing in Scientific American, “Time is in fact the hero of the plot.” Since he believed there were billions of years available for the origin of life on Earth, Wald poetically hoped, “Given so much time, the ‘impossible’ becomes possible, the possible probable, and the probable virtually certain. One only has to wait: Time itself performs the miracles.”1 But time isn’t unlimited.  

A Hostile Environment 

First, the early Earth was a hostile environment for any nascent biomolecules and even early life. While the Earth formed at about 4.54 billion years ago, the crust did not begin to solidify until about 4.4 to perhaps as late as 4 billion years ago.2 Second, large bolide impact events occurred during the “heavy bombardment period” which lasted on Earth until about 3.8 billion years ago3 — impacts large enough to vaporize the oceans and sterilize Earth’s surface of any early life or prebiotic molecules.4 Third, there is now good evidence of cellular life existing as early as 3.77 billion years ago based upon the presence of microfossils in jasper cherts in the Nuvvuagittuq belt in Quebec, Canada.5


Does this evidence imply less than 30 million years from the point at which Earth became habitable to the evidence of the first life? That may seem like a long time, but on geological timescales it is considered short.  

The Earliest Life 

Indeed, decades after Wald, such fossil evidence of early life led theorists to say things like “we are left with very little time between the development of suitable conditions for life on the Earth’s surface and the origin of life”6 and “we are now thinking, in geochemical terms, of instant life…”7 While the precise dates of the earliest life and estimates of the onset of Earth habitability vary and these issues are debated vigorously in the literature, the point is clear: There is not unlimited time for the origin of life. 


Time is not the hero of the plot; rather, it is the antagonist. The Herculean feats required by origin-of-life models are matched only by the poverty of resources available on the early Earth in terms of time and available chemical reactants. No wonder Francis Crick, the Nobel Prize-winning biochemist who co-discovered the structure of DNA, lamented, “An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle.”8 Based upon current knowledge, the first life could not have arisen by purely natural means.

The Origin of Life's antiDarwinian bias continued some more.

 Still Unexplained: The First Living Cell 

Walter Bradley

Casey Luskin 

Editor’s note: We are delighted to present a series by Walter Bradley and Casey Luskin on the question, “Did Life First Arise by Purely Natural Means?” This is the seventh entry in the series, a modified excerpt from the recent book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos. Find the full series so far here.  

In recent years, MIT physicist Jeremy England (pictured above) has gained media attention for proposing a thermodynamic energy-dissipation model of the origin of life. England’s view was summarized when he famously said that the origin and evolution of life “should be as unsurprising as rocks rolling downhill.” He continued, “You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant.”1Another physicist, ID theorist Brian Miller, has responded to England’s research.


Miller points out that the kind of energy that dissipates as a result of the sun shining on the Earth or other natural processes cannot explain how living systems have both low entropy (disorder) and high energy. As Miller puts it: “These are unnatural circumstances. Natural systems never both decrease in entropy and increase in energy — not at the same time.” Living cells do this “by employing complex molecular machinery and finely tuned chemical networks to convert one form of energy from the environment into high-energy molecules” — things that cannot be present prior to the origin of life because they must be explained by the origin of life. Without this cellular machinery to harness energy from the environment and drive down entropy, England’s energy-dissipation models cannot do the task they’ve been handed. As Miller said, England’s model cannot account for the origin of biological information, which “is essential for constructing and maintaining the cell’s structures and processes.”2 

A Crucial Deficiency 

Miller has highlighted a crucial deficiency in origin-of-life models: What is the origin of the cellular machinery, and the information that encodes the machinery that undergirds even the simplest cell? Forming a self-replicating RNA molecule, a seemingly impossible task under natural Earth conditions, is still a far cry from producing all the vast machinery required by cells to exist. A final obstacle for the RNA world — and any naturalistic account of the origin of life — is therefore its inability to explain the origin of the genetic code and the molecular machinery of life. 


There is an important distinction between the genetic code and the information in DNA or RNA: The genetic code is essentially the language in which the genetic information in the DNA or RNA is written. In order to evolve into the DNA/protein-based life that exists today, the RNA world would need to evolve the ability to convert genetic information into proteins. However, this process of transcription and translation requires a large suite of proteins and molecular machines — which themselves are encoded by genetic information. This poses a chicken-and-egg problem, where essential enzymes and molecular machines are needed to perform the very task that constructs them


To appreciate the obstacle this poses to materialistic accounts of the origin of life, consider the following analogy. If you have ever watched a DVD, you know that it is rich in information. However, without the machinery of a DVD player to read the disk, process its information, and convert it into a picture and sound, the disk would be useless. But what if the instructions for building the first DVD player were only found encoded on a DVD? You could never play the DVD to learn how to build a DVD player. So how did the first disk and DVD player system arise? The answer is obvious: Intelligent agents designed both the player and the disk at the same time, and purposefully arranged the information on the disk in a language that could be read by the player. 

The Proper Machinery 

In the same way, genetic information could never be converted into proteins without the proper machinery. Yet the machines required for processing the genetic information in RNA or DNA are encoded by those same genetic molecules — they perform and direct the very task that builds them. This system cannot exist unless both the genetic information and transcription/translation machinery are present at the same time, and unless both speak the same language. A functional living cell therefore can’t evolve in a piecemeal fashion, but the likelihood of it arising all at once by unguided natural processes is far too low to be considered a viable model. 


Biologist Frank Salisbury explained this problem in American Biology Teacher in 1971, not long after the workings of the genetic code were first uncovered: 

It’s nice to talk about replicating DNA molecules arising in a soupy sea, but in modern cells this replication requires the presence of suitable enzymes…[T]he link between DNA and the enzyme is a highly complex one, involving RNA and an enzyme for its synthesis on a DNA template; ribosomes; enzymes to activate the amino acids; and transfer-RNA molecules…How, in the absence of the final enzyme, could selection act upon DNA and all the mechanisms for replicating it? It’s as though everything must happen at once: the entire system must come into being as one unit, or it is worthless. There may well be ways out of this dilemma, but I don’t see them at the moment.3 

An Unsolved Problem 

The same problem confronts modern RNA world researchers, and it remains unsolved. As two theorists observed in a 2004 article in Cell Biology International: 

The nucleotide sequence is also meaningless without a conceptual translative scheme and physical “hardware” capabilities. Ribosomes, tRNAs, aminoacyl tRNA synthetases, and amino acids are all hardware components of the Shannon message “receiver.” But the instructions for this machinery is itself coded in DNA and executed by protein “workers” produced by that machinery. Without the machinery and protein workers, the message cannot be received and understood. And without genetic instruction, the machinery cannot be assembled.4 

Unless origin-of-life theorists can account for (1) the molecular machinery of the cell, (2) the information which encodes that machinery, and (3) the ability of cells to process that information to construct this machinery via a genetic code, the origin of even the simplest cell remains unexplained. Perhaps these seemingly intractable fundamental problems have an out: lots of time.

What is meant by 'Son of God'?

Acts17:28KJV"For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring. (or he is our Father)" 

Luke 3:38NIV"the son of Enosh, the son of Seth, the son of Adam, the son of God." 

John 6:57NKJV "57As the living Father sent Me, and I live because of the Father(i.e the Father caused me to live), so(in the same manner) he who feeds on Me will live because of Me."  

Luke 1:35NKJV"The angel answered, “The Holy Spirit will come on you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God." 

Acts13:33NKJV"God has fulfilled this for us their children, in that He has raised up Jesus. As it is also written in the second Psalm:

‘You are My Son,
Today I have begotten You.’"   note please that JEHOVAH'S restoring of his Son's life is spoken of as his begetting him anew. 

Proverbs8:22NJB"Yahweh created me, first-fruits of his fashioning, before the oldest of his works." 

To be clear JEHOVAH'S Wisdom is eternal hence uncreated like its possessor. Thus the passage speaks of the initial expression of this wisdom and not the wisdom itself. 

Proverbs8:30NJB"I was beside the master craftsman, delighting him day after day, ever at play in his presence," Then this living derivative of JEHOVAH'S Wisdom proceeds to glorify its source by doing praiseworthy work. 

Colossians1:15_16NJB"He is the image of the unseen God, the first-born of all creation,

16 for in him were created all things in heaven and on earth: everything visible and everything invisible, thrones, ruling forces, sovereignties, powers -- all things were created through him and for him." Clearly a reference to proverbs8:22-30.

1Corinthians1:24NIV"but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God." He is called logos one of the meanings of which is logic. He is JEHOVAH'S living rebuttal to those who accuse him of being a poor Father. He can only serve this purpose If he is truly  a Son i.e owes his life/existence to his Father.

On the big bang and Occam's razor.

Theoretical Physicist Sabine Hossenfelder on the Deficiency of Alternative Models to Big Bang Cosmology  

Brian Miller 

Theoretical physicist Sabine Hossenfelder recently posted a very informative video asking “Did the Big Bang happen?” She explains why alternative theories to the Big Bang model fail to better explain the cosmological data. She also unintentionally affirms the fine-tuning argument for design in the universe.  

Success of the Big Bang Theory 

Hossenfelder begins by summarizing the evidence for Big Bang cosmology based on Einstein’s theory of relativity and the observed expansion of space. She also explains why the exact details of the early universe remain a mystery. Cosmologists have a limited understanding of the physics of this time when the energy of particles exceeded what the Large Hadron Collider at CERN could generate. In addition, elucidating the dynamics of the universe’s earliest epoch requires a theory of quantum gravity, which does not currently exist. 


Even given these limitations, the Big Bang theory represents the best model since it is founded on general relativity, and Einstein’s theory is supported by numerous pieces of observational evidence such as the bending of light around stars. In addition, the standard model (i.e., Big Bang model with a cosmological constant and cold dark matter) predicts many observations such as the Cosmic Microwave Background and the galactic filaments using simple initial conditions. The universe’s initial state is assumed to approximate a uniform distribution of mass-energy. 


The standard model thus provides a “simple” explanation for the current state of the universe since it requires few variables. These include the variables in the relatively simple equations for the expansion of the universe, the initial mass-energy density, and the initial expansion rate. 

Deficiency of Other Models 

Hossenfelder then provides a deeply insightful exposition on the inferiority of other models. All other models rely on different equations for the dynamics of the early universe. But these equations can only generate our current state by choosing far more complex initial conditions: 

…Einstein’s equations together with their initial values in the early universe provide a simple explanation for the observations we make today. When I say simple, I mean simple in a quantitative way you need few numbers to specify. If you used a different equation, then the initial state would be more difficult. You’d need to put in more numbers. And the theory wouldn’t explain as much. 

The key problem is that nearly any set of equations could yield the current state of the universe with the right choice of initial conditions. But neither the theory’s underlying equations nor the initial conditions can be independently verified. And the alternative theories provide no additional knowledge. Hossenfelder summarizes as follows:  

And then they also need a different initial state, so you might no longer find a Big Bang. As I said earlier, you can always do this, because for any evolution law there will be some initial state that will give you the right prediction for today. The problem is that this makes a simple explanation more complicated, so these theories are not scientifically justifiable. They don’t improve the explanatory power of the standard cosmological model. Another way to put it is that all those complicated ideas for how the universe began are unnecessary to explain what we observe. 

The God Hypothesis 

Hossenfelder lists several theories that fall under her critique including Penrose’s cyclic cosmology, the ekpyrotic universe that postulates colliding membranes, and the no-boundary proposal by Jim Hartle and Stephen Hawking. Stephen Meyer also critiqued these theories in his book Return of the God Hypothesis. But Meyer came to starkly different conclusions.


Hossenfelder concludes that “we are facing the limits of science itself.” And the question of the universe’s origin “we’ll never be able to answer.” In contrast, Meyer argues that the evidence for a beginning and the required fine tuning of the universe to support life point to a mind behind our world. The fact that all alternative cosmological theories require highly specific initial conditions to explain our present life-friendly universe only reinforces the fine-tuning argument and by extension the God Hypothesis

Alternate titles: Day of Judgment, Day of Remembrance, Rosh Ha-shanah, Rosh Hashanah, Yom Ha-Zikkaron, Yom Teruah

By The Editors of Encyclopaedia Britannica • Edit History

Rosh Hashana, (Hebrew: “Beginning of the Year”) , Hashana also spelled Hashanah or Ha-shanah, also called Day of Judgment or Day of Remembrance, a major Jewish observance now accepted as inaugurating the religious New Year on Tishri 1 (September or October). Because the New Year ushers in a 10-day period of self-examination and penitence, Rosh Hashana is also called the annual Day of Judgment; during this period each Jew reviews his relationship with God, the Supreme Judge. A distinctive feature of the liturgy is the blowing of the ram’s horn (shofar) as prescribed in Numbers 29:1; the notes of the shofar call the Jewish people to a spiritual awakening associated with the revelation to Moses on Mount Sinai. During the Additional Service in the synagogue, the shofar is sounded after the recital of each of three groups of prayers. Rosh Hashana is observed Monday, September 26, 2022. Rosh Hashana is also known as the Day of Remembrance, for on this day Jews commemorate the creation of the world, and the Jewish nation recalls its responsibilities as God’s chosen people. 


On the first night of Rosh Hashana a New Year’s custom dictates that delicacies be prepared as omens of good luck. On the following night bread and fruit, dipped in honey, are customarily eaten, and a special blessing is recited. Rosh Hashana is the only festival observed for two days in Israel.

Yet more on the origin of life's antiDarwinian bias.

Origin of the First Self-Replicating Molecules 
Walter Bradley
Casey Luskin
 
Editor’s note: We are delighted to present a series by Walter Bradley and Casey Luskin on the question, “Did Life First Arise by Purely Natural Means?” This is the sixth entry in the series, a modified excerpt from the recent book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos. Find the full series so far here.   

In an undergraduate seminar taught by Stanley Miller that I (Casey Luskin) took as a student at the University of California, San Diego, Dr. Miller taught us that “making compounds and making life are two different things.”1 Many variants of Stanley Miller’s experimental setup have been used in attempting to demonstrate the conversion of energy-rich, gaseous-phase chemicals into amino acids and other biomolecular monomers. But this is not nearly sufficient to generate life. Any origin-of-life explanation must include plausible biochemical paths from individual bio-building blocks like amino acids or nucleic acids to functional polymers such as proteins and DNA. The origin-of-life explanation must also include ways to speed up chemical reactions that are naturally slow. In living cells, long chains of amino acids fold up into 3-D structures that allow them to function as enzymes that greatly accelerate chemical reactions, as seen in the figure below. How could these arise before life existed? More importantly, any origin-of-life model must account for the very particular sequencing of the molecules — i.e., the ordering of amino acids in proteins and nucleotide bases in RNA and DNA that allows them to function properly. This means explaining a crucial aspect of life: the origin of its information, or what proponents of intelligent design (ID) call the “information sequence problem.” 

The Most Popular Proposal  
For some theorists, the origin of life is defined as the natural origin of a self-replicating system capable of undergoing Darwinian evolution.2 The most popular proposal for the first self-replicating molecule is RNA — where life was first based upon RNA carrying both genetic information (akin to modern DNA) and performing catalytic functions (akin to modern enyzmes), in what is termed the RNA world. Before we delve deeply into that, it is instructive to use the proceedings of a conference organized by the International Society for the Study of the Origin of Life (ISSOL) at the University of California, Berkeley, in 1986 to measure the progress that has been made in origin-of-life research from 1952-1986. 

I (Walter Bradley) attended this conference and watched one of the plenary sessions devoted to a spirited debate between scientists who believed that the first life was made of DNA (“DNA-first”) and those who believed that the first biomolecules were proteins (“protein-first”). Neither group had yet been able to synthesize under plausible conditions either protein or DNA. Proteins can act as a chemical catalyst. DNA is the repository of information that is used to make functional protein. One of the outcomes from the conference was the sense that neither protein-first nor DNA-first were promising pathways to explaining the origin of life. But the difficulty demonstrating a plausible biochemical pathway for the origin of life that went through DNA-first or protein-first created an openness to new alternative possibilities. In 1986, the RNA world was just emerging as a popular alternative to protein-first or DNA-first models.

At the concluding plenary session, leading origin-of-life researcher Robert Shapiro addressed the RNA world and traced citations in the biochemical literature of the synthesis of RNA molecules under conditions thought to represent the early Earth conditions. The results were shocking. He cited a 1986 paper indicating RNA synthesis under prebiotic conditions had been demonstrated repeatedly, citing a 1985 paper and alluding to others. But that 1985 paper did not present original work — rather, it cited a 1984 paper and went all the way back to 1968 without any original work cited. A close reading of the 1968 paper indicated that the authors thought that they might have synthesized RNA molecules under prebiotic conditions but had not actually found any.  

Five Huge Barriers 
Shapiro’s talk subsequently presented five huge barriers to this biochemical pathway from prebiotic chemistry to the first living systems. At the end of his dramatic presentation, the room of most of the world’s most active origin-of-life researchers fell silent. The chair of the session, who was also the editor of the premiere journal Origins of Life and Evolution of Biospheres, repeatedly invited questions from the stunned audience. It was the only time in my (Walter Bradley) professional lifetime that I attended a plenary session of scientists and engineers where there were no questions. The chair closed the session without any questions offered, and he closed with the comment, “Robert, do you have to be so pessimistic?” Robert did not reply, but might have said he was letting the data do the talking, and the data told a very pessimistic story. 

History has confirmed Shapiro’s pessimism. Despite these difficulties, to this day, the RNA world remains the most popular model for the origin of life. But there are major problems with the RNA world hypothesis and claims that a self-replicating RNA molecule appeared by pure chance. 

First, RNA has not been shown to assemble in a laboratory without the help of a skilled chemist intelligently guiding the process. Origin-of-life theorist Steven Benner explained that a major obstacle to the natural production of RNA is that “RNA requires water to function, but RNA cannot emerge in water, and does not persist in water without repair” due to water’s “rapid and irreversible” corrosive effects upon RNA.3 In this “water paradox,” Benner explains that “life seems to need a substance (water) that is inherently toxic to polymers (e.g., RNA) necessary for life.”4

To overcome such difficulties, Benner and other chemists carefully designed experimental conditions that are favorable to the production of RNA. But Robert Shapiro explains that these experiments do not simulate natural conditions: “The flaw is in the logic — that this experimental control by researchers in a modern laboratory could have been available on the early Earth.”5 Reviewing attempts to construct RNA in the lab, James Tour likewise found that “[t]he conditions they used were cleverly selected,” but in the natural world, “the controlled conditions required to generate” RNA are “painfully improbable.”6 Origin-of-life theorists Michael Robertson  and Gerald Joyce even called the natural origin of RNA a “Prebiotic Chemist’s Nightmare” because of “the intractable mixtures that are obtained in experiments designed to simulate the chemistry of the primitive Earth.”7 In the end, these experiments demonstrate one thing: RNA can only form by intelligent design. 

A Second Problem 
Today, RNA is capable of carrying genetic information, but RNA world advocates claim that in the past, it also fulfilled the kinds of catalytic roles that enzymes perform today. A second problem with the RNA world is that RNA molecules do not exhibit many of the properties that allow proteins to serve as worker molecules in the cell. While RNA has been shown to perform a few roles, there is no evidence that it could perform all necessary cellular functions.8 As one paper put it, proteins are “one million times fitter than RNA as catalysts” and “[t]he catalytic repertoire of RNA is too limited.”9 
The Origin of Information 
The most fundamental problem with the RNA world hypothesis is its inability to explain the origin of information in the first self-replicating RNA molecule — which experts suggest would have had to be at least 100 nucleotides long, if not between 200 and 300 nucleotides in length.10 How did the nucleotide bases in RNA become properly ordered to produce life? There are no known chemical or physical laws that can do this. To explain the ordering of nucleotides in the first self-replicating RNA molecule, origin-of-life theorists have no explanation other than blind chance. As noted, ID theorists call this obstacle the information sequence problem, but multiple mainstream theorists have also observed the great unlikelihood of naturally producing a precise RNA sequence required for replication. Shapiro puts the problem this way: 

A profound difficulty exists, however, with the idea of RNA, or any other replicator, at the start of life. Existing replicators can serve as templates for the synthesis of additional copies of themselves, but this device cannot be used for the preparation of the very first such molecule, which must arise spontaneously from an unorganized mixture. The formation of an information-bearing homo-polymer through undirected chemical synthesis appears very improbable.11 

Elsewhere, Shapiro notes, “The sudden appearance of a large self-copying molecule such as RNA was exceedingly improbable” with a probability that “is so vanishingly small that its happening even once anywhere in the visible universe would count as a piece of exceptional good luck.”12 A 2020 paper in Scientific Reports similarly notes, “Abiotic emergence of ordered information stored in the form of RNA is an important unresolved problem concerning the origin of life” because “the formation of such a long polymer having a correct nucleotide sequence by random reactions seems statistically unlikely.”13 Steven Benner refers to the “Information-Need Paradox,” where self-replicating RNA molecules would be “too long to have arisen spontaneously” from available building blocks.14 Benner raises an additional logical difficulty in that generating an RNA molecule capable of catalyzing its own replication is much less likely than generating RNA molecules that catalyze the destruction of RNA. This suggest a grave theoretical difficulty where RNA world theorists are faced with a “chemical theory that makes destruction, not biology, the natural outcome.”15 
An Intractable Problem 
The paper in Scientific Reports proposed a solution to these quandaries that showed just how intractable this problem is: It concluded that because the formation of a single self-replicating RNA molecule is prohibitively unlikely in the observable universe, and therefore the universe must be far larger than we observe — an “inflationary universe” that increases the probabilistic resources until such an unlikely event becomes likely. This is just like the materialist response to the fine-tuning of physics: When the observed specificity of nature appears to indicate design, they invent multiverses to overcome probabilistic difficulties. When RNA world theorists are appealing to the origin-of-life’s version of the multiverse to avoid falsification, it’s clear that their project has fatal problems.

What does the origin of life have to do with Darwinism?

It has become obvious to many, present company included, that Darwinism is less about explaining the origins of anything,and more about explaining away the technology manifest in living systems. That being the case the origin of life is very relevant . Being prebiotic, the origin of life is by definition pre Darwinian ,thus if the technology that Darwinists are attempting to explain away via their theory precedes Darwinian evolution that would certainly constitute a fail. 

Why no rise of the machines.

 New from Science Uprising — Artificial Intelligence, Creativity, and the Human Difference 

David Klinghoffer 

The latest Science Uprising episode is out and what it has to say is important. From the late Stephen Hawking to Elon Musk, some of the smartest people on Earth have issued warnings about the looming danger posed by artificial intelligence. Not only is AI an amazing technology, they say, with the potential for uses both good and bad, but it threatens to replace and destroy humanity. The media love this particular concept and continually seek to scare us with it. Why?


The episode calls out the idea for what it is: applied materialism. Materialism is the denial of a spiritual reality. It animates Darwinian thinking, and it drives the panic about AI. After all, if humans are no more than “meat machines,” then a superior machine, equipped with AI, could well choose to do away with us. However, as four notable scholars explain here, AI runs on algorithms, which are essentially a recipe. AI does only what it’s programmed to do. Humans transcend algorithms. We do things that computers will never be able to accomplish: 

An Unexpected Gift 

Interviewed for the episode, Robert J. Marks, John Lennox, Jay Richards, and Selmer Bringsjord have profound things to teach. Dr. Marks, for example, is a renowned computer engineer at Baylor University who directs Discovery Institute’s Bradley Center for Natural and Artificial Intelligence. He says that by its nature, AI is locked in a silo or box where it exercises its ability to run algorithms. Creativity, not mere copying or following commands, entails thinking “outside the box.” That’s how it can surprise us with genuine novelty. It’s why new ideas often come to us from out of the blue: not summoned but given as an unexpected gift.


This, too, may be why artists notoriously live disordered lives, and why totalitarian societies are typically poor in art (as distinct from kitsch or propaganda) and in creativity generally. The regimentation is not compatible with giving free rein to the human difference. It’s something to think about as rule by authoritarian experts becomes more and more the expectation in our own culture. Young people especially need to understand this.

 The “Clumping” Problem and the Origin of Life 

Walter Bradley

Casey Luskin 

 Editor’s note: We are delighted to present a series by Walter Bradley and Casey Luskin on the question, “Did Life First Arise by Purely Natural Means?” This is the fifth entry in the series, a modified excerpt from the recent book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos. Find the full series so far here. 

Assuming that prebiotic organic polymers could be created under some set of natural conditions, the origin of life still cannot occur unless the requisite molecules can be concentrated or “clumped” together in some protective container where necessary chemical reactions can take place. In living organisms, such environments are the basic unit of life — the cell. But could something like a cell membrane arise naturally before life existed? 


In the 1970s, biochemist Sidney Fox and colleagues believed they had uncovered primitive cell membrane-like structures called protenoid microspheres.1 Other structures called coacervates were proposed, first by Oparin, as potential precursors to modern cell membranes.2 Because these structures lack any metabolism and the ability to self-reproduce,3they clearly could not constitute life. But even if these structures could do those things, they are unable to perform the most basic protective function of cell membranes: discriminate among nutrients, waste products, and toxic chemicals. 


Campbell’s Biology, a prominent college-level biology textbook, explains this requirement: 

One of the earliest episodes in the evolution of life may have been the formation of a membrane that enclosed a solution different from the surrounding solution while still permitting the uptake of nutrients and elimination of waste products. The ability of the cell to discriminate in its chemical exchanges with its environment is fundamental to life, and it is the plasma membrane and its component molecules that make this selectivity possible.4 

A Smart, Active Gatekeeper 

Undoubtedly the textbook is correct: Without this extremely important protective barrier, the earliest forms of life would be unable to obtain food and be vulnerable to harmful molecules and chemical reactions in the outside environment, such as oxidation. The membrane also keeps the cell’s components together to allow for necessary cellular processes to take place. But the “lipid bilayer” of modern cells is no mere passive wall — it’s a smart, active gatekeeper capable of allowing water and nutrients in, and letting waste products out. Specialized machines embedded in this smart membrane discriminate between helpful and harmful substances through a variety of biochemical pathways and molecular pumps. Hence the problem for origin-of-life theorists — as synthetic chemist James Tour of Rice University explains, no origin-of-life experiments have ever created “the required passive transport sites and active pumps for the passage of ions and molecules through bilayer membranes.”5 

Daunting Complexity 

Tour elaborates on the daunting complexity of cell membranes that remains unexplained by origin-of-life theorists:


Researchers have identified thousands of different lipid structures in modern cell membranes. These include glycerolipids, sphingolipids, sterols, prenols, saccharolipids, and polyketides. For this reason, selecting the bilayer composition for our synthetic membrane target is far from straightforward. When making synthetic vesicles — synthetic lipid bilayer membranes — mixtures of lipids can, it should be noted, destabilize the system.

Lipid bilayers surround subcellular organelles, such as nuclei and mitochondria, which are themselves nanosystems and microsystems. Each of these has their own lipid composition.

Lipids have a nonsymmetric distribution. The outer and inner faces of the lipid bilayer are chemically inequivalent and cannot be interchanged.6

Despite modest progress with the synthetic production of microspheres, coacervates, and similar structures, the lack of any discrimination ability means the clumping step in the origin of life has not been explained.

Science is catching up with God?

Meyer: Webb Telescope Confirms a Cosmic Beginning

David Klinghoffer 

One of the three pillars of Stephen Meyer’s “God Hypothesis” argument is the fact that the universe had a beginning a finite time ago. Or is it a fact? A physics researcher, Eric Lerner, won himself some big media time recently with the claim that images from the new James Webb Space Telescope (JWST) were casting serious doubt on the Big Bang. The images showed far too many fully formed galaxies too soon after the universe began, according to the Big Bang theory. Did this hint that the universe, in fact, had no beginning, at least as we understand that?


Writing at The Daily Wire, Dr. Meyer examines Lerner’s case and explains what’s wrong with it. The question has to do with red-shifted (i.e., stretched out) radiation and so-called “tired light.” 

If the JWST were to detect “uber” red shifted radiation coming from extremely ancient, distant galaxies, that would provide additional confirmation that the universe has expanded as much as the Big Bang theory predicts. 


So has the JWST detected such radiation? It has. In fact, there would be no extremely distant galaxies to analyze had the JWST not detected long wavelength infrared radiation coming from them. Remember the JWST was specifically designed to detect such infrared radiation. Thus, the fact that it has been able to produce images of extremely distant galaxies shows that it has collected the kind of radiation astronomers would expect if the universe is expanding as the Big Bang theory affirms. 


Lerner mentions none of this. Instead, he highlights surprising discoveries about how many galaxies had formed in those remote periods in cosmic history. He argues that, given current theory, we should not expect to see so many galaxies so early. 


Perhaps. But the evidence he cites challenges models of galaxy formation, not an expanding universe or the Big Bang. 


Interestingly, Lerner acknowledges that the JWST has detected extremely red-shifted radiation. But he explains this away with something called the “tired-light hypothesis.” He acknowledges that wavelengths increase with distance but denies the expansion of space produces that elongation. Instead, he asserts light stretches out as it loses energy in transit. 


Yet the tired-light hypothesis has been discredited. No known mechanism degrades the energy of a photon of light without changing its direction and momentum. But any such change would cause images of the object emitting the photon to blur. That blurring has not been observed. 


Lerner’s arguments have also been rejected because of other astronomical evidence — the observed abundance of light elements and the famed “Cosmic Background ” — that the Big Bang model explains uniquely well. 

“In the Beginning…”

In Return of the Hypothesis, Meyer recounts why scientists, even Einstein, resisted the Big Bang as it was formulated initially by Georges Lemaître. The philosophical stakes were just too enormous. Materialism could not accept so massive a confirmation of Genesis 1:1: “In the beginning…”


Because of this, even as Lerner’s bid for publicity will be a thing of the past soon enough, you can be sure that an atmosphere of nervousness about cosmology and what it teaches will persist. Just in the past month, physicist Sabine Hossenfelder asked, “Did the Big Bang happen?” (Her answer: We can’t know how the universe originated, if it did.) And Scientific American proclaimed, without a mention of Lerner, “JWST’s First Glimpses of Early Galaxies Could Break Cosmology.” These are challenges that are NOT going away. 



 

Yet another rant against post millenialism

 Luke18:8KJV"I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?"  

A balanced consideration of this text would certainly not leave a fair minded truthseeker with the impression that our Lord expected to find (true) Christianity having gained universal(or even widespread)  acceptance upon his return.

Revelation3:9KJV"Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life. " 

So rather than being rendered impotent during the church's time on earth , Satan retains rulership over the Government's of this age . This fact test the ( true) church "10 days" i.e the entirety of the end times. Doesn't sound very post millenialist to me. 

Revelation16:8,9KJV"8And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire. 9And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory." 

Again our Lord puts true Christians on notice that in this present age there will never be any heeding of the warning that JEHOVAH is giving through his loyalists, bible truth and those promulgating it will continue to be treated with contempt until the Lord JEHOVAH reasserts his rightful sovereignty over this planet.

Forming Polymers: A Problem for the Origin of Life 

Walter Bradley 

Casey Luskin 

Editor’s note: We are delighted to present a series by Walter Bradley and Casey Luskin on the question, “Did Life First Arise by Purely Natural Means?” This is the fourth entry in the series, a modified excerpt from the recent book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos. Find the full series so far here. 

Assume for a moment that there was some way to produce simple organic molecules on the early Earth. Perhaps these molecules did form a primordial soup, or perhaps they arose near some high-energy hydrothermal vent. Either way, origin-of-life theorists must then explain how amino acids or other key organic molecules linked up to form long chains (polymers), thereby forming proteins or RNA through a process called polymerization. 

A Popular Model 

A problem for the primordial soup version of this model is that it would be at chemical equilibrium, without any free energy for organic monomers to react further.1 Indeed, chemically speaking, the last place you would want to link amino acids or other monomers into chains would be a vast, water-based environment like the primordial soup or in the ocean near a hydrothermal vent. As the U.S. National Academy of Sciences acknowledges, “Two amino acids do not spontaneously join in water. Rather, the opposite reaction is thermodynamically favored.”2 Origin-of-life theorists Stanley Miller and Jeffrey Bada similarly acknowledged that the polymerization of amino acids into peptides “is unfavorable in the presence of liquid water at all temperatures.”3 In other words, water breaks protein chains of monomers back down into amino acids (or other constituents), making it very difficult to produce proteins (or other polymers like RNA) in the primordial soup or underwater near a hydrothermal vent. 


The hydrothermal vent model is popular among origin-of-life theorists because it represents a high-energy environment, but this model faces additional problems. Hydrothermal vents tend to be short-lived, lasting perhaps only hundreds of years4 — timescales so short that the origin of life at undersea vents has been said to be “essentially akin to spontaneous generation.”5 It is also difficult to envision how prebiotic chemicals could become concentrated in such a chaotic, unbounded oceanic environment.6 

The Biggest Obstacle 

But perhaps the biggest obstacle to the origin of life at hydrothermal vents is implied in their name: extremely high temperatures. According to Scientific American, experiments by Miller and Bada on the durability of prebiotic compounds near vents showed that the superheated water would “destroy rather than create complex organic compounds.”7


In the view of Miller and Bada, “organic synthesis would not occur in hydrothermal vent waters,” indicating that vents are not an option for the origin of life because “[a]ny origin-of-life theory that proposes conditions of temperature and time inconsistent with the stability of the compounds involved can be dismissed solely on that basis.”8 Some might reply that certain alkaline thermal vents have lower temperatures,9 but the high pH present near alkaline vents tend to precipitate carbon into carbonate minerals, with very little carbon remaining in the seawater for prebiotic chemical reactions,10 and such a high pH is highly destructive to RNA.11 As one paper put it, “the evolution of RNA is unlikely to have occurred in the vicinity of an alkaline deep-sea hydrothermal vent.”12

The Manhattan project a brief history.

Manhattan Project, U.S. government research project (1942–45) that produced the first atomic bombs.

American scientists, many of them refugees from fascist regimes in Europe, took steps in 1939 to organize a project to exploit the newly recognized fission process for military purposes. The first contact with the government was made by G.B. Pegram of Columbia University, who arranged a conference between Enrico Fermi and the Navy Department in March 1939. In the summer of 1939, Albert Einstein was persuaded by his fellow scientists to use his influence and present the military potential of an uncontrolled fission chain reaction to Pres. Franklin D. Roosevelt. In February 1940, $6,000 was made available to start research under the supervision of a committee headed by L.J. Briggs, director of the National Bureau of Standards (later National Institute of Standards and Technology). On December 6, 1941, the project was put under the direction of the Office of Scientific Research and Development, headed by Vannevar Bush. 

After the U.S. entry into World War II, the War Department was given joint responsibility for the project, because by mid-1942 it was obvious that a vast array of pilot plants, laboratories, and manufacturing facilities would have to be constructed by the U.S. Army Corps of Engineers so that the assembled scientists could carry out their mission. In June 1942 the Corps of Engineers’ Manhattan District was initially assigned management of the construction work (because much of the early research had been performed at Columbia University, in Manhattan), and in September 1942 Brig. Gen. Leslie R. Groves was placed in charge of all Army activities (chiefly engineering activities) relating to the project. “Manhattan Project” became the code name for research work that would extend across the country. It was known in 1940 that German scientists were working on a similar project and that the British were also exploring the problem. In the fall of 1941 Harold C. Urey and Pegram visited England to attempt to set up a cooperative effort, and by 1943 a combined policy committee with Great Britain and Canada was established. In that year a number of scientists of those countries moved to the United States to join the project there.


If the project were to achieve success quickly, several lines of research and development had to be carried on simultaneously before it was certain whether any might succeed. The explosive materials then had to be produced and be made suitable for use in an actual weapon. 

Uranium-235, the essential fissionable component of the postulated bomb, cannot be separated from its natural companion, the much more abundant uranium-238, by chemical means; the atoms of these respective isotopes must rather be separated from each other by physical means. Several physical methods to do this were intensively explored, and two were chosen—the electromagnetic process developed at the University of California, Berkeley, under Ernest Orlando Lawrence and the diffusion process developed under Urey at Columbia University. Both of these processes, and particularly the diffusion method, required large, complex facilities and huge amounts of electric power to produce even small amounts of separated uranium-235. Philip Hauge Abelson developed a third method called thermal diffusion, which was also used for a time to effect a preliminary separation. These methods were put into production at a 70-square-mile (180-square-km) tract near Knoxville, Tennessee, originally known as the Clinton Engineer Works, later as Oak Ridge 


Only one method was available for the production of the fissionable material plutonium-239. It was developed at the metallurgical laboratory of the University of Chicago under the direction of Arthur Holly Compton and involved the transmutation in a reactor pile of uranium-238. In December 1942 Fermi finally succeeded in producing and controlling a fission chain reaction in this reactor pile at Chicago. 

Quantity production of plutonium-239 required the construction of a reactor of great size and power that would release about 25,000 kilowatt-hours of heat for each gram of plutonium produced. It involved the development of chemical extraction procedures that would work under conditions never before encountered. An intermediate step in putting this method into production was taken with the construction of a medium-size reactor at Oak Ridge. The large-scale production reactors were built on an isolated 1,000-square-mile (2,600-square-km) tract on the Columbia River north of Pasco, Washington—the Hanford Engineer Works. 

Before 1943, work on the design and functioning of the bomb itself was largely theoretical, based on fundamental experiments carried out at a number of different locations. In that year a laboratory directed by J. Robert Oppenheimer was created on an isolated mesa at Los Alamos, New Mexico, 34 miles (55 km) north of Santa Fe. This laboratory had to develop methods of reducing the fissionable products of the production plants to pure metal and fabricating the metal to required shapes. Methods of rapidly bringing together amounts of fissionable material to achieve a supercritical mass (and thus a nuclear explosion) had to be devised, along with the actual construction of a deliverable weapon that would be dropped from a plane and fused to detonate at the proper moment in the air above the target. Most of these problems had to be solved before any appreciable amount of fissionable material could be produced, so that the first adequate amounts could be used at the fighting front with minimum delay. 

By the summer of 1945, amounts of plutonium-239 sufficient to produce a nuclear explosion had become available from the Hanford Works, and weapon development and design were sufficiently far advanced so that an actual field test of a nuclear explosive could be scheduled. Such a test was no simple affair. Elaborate and complex equipment had to be assembled so that a complete diagnosis of success or failure could be had. By this time the original $6,000 authorized for the Manhattan Project had grown to $2 billion. 

The first atomic bomb was exploded at 5:30 AM on July 16, 1945, at a site on the Alamogordo air base 120 miles (193 km) south of Albuquerque, New Mexico. It was detonated on top of a steel tower surrounded by scientific equipment, with remote monitoring taking place in bunkers occupied by scientists and a few dignitaries 10,000 yards (9 km) away. The explosion came as an intense light flash, a sudden wave of heat, and later a tremendous roar as the shock wave passed and echoed in the valley. A ball of fire rose rapidly, followed by a mushroom cloud extending to 40,000 feet (12,200 metres). The bomb generated an explosive power equivalent to 15,000 to 20,000 tons of trinitrotoluene (TNT); the tower was completely vaporized and the surrounding desert surface fused to glass for a radius of 800 yards (730 metres). The following month, two other atomic bombs produced by the project, the first using uranium-235 and the second using plutonium, were dropped on Hiroshima and Nagasaki, Japan.

A Mystery: Prebiotic Synthesis of Simple Organic Monomers 

Walter Bradley

Casey Luskin 

Editor’s note: We are delighted to present a series by Walter Bradley and Casey Luskin on the question, “Did Life First Arise by Purely Natural Means?” This is the third entry in the series, a modified excerpt from the recent book The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions About Life and the Cosmos. Find the full series so far here. 

The Miller-Urey experiments were conducted in 1952–19531 and were celebrated as a great breakthrough in the search for a chemical pathway from gases assumed to be present in the early Earth’s atmosphere to chemical reactions that produced amino acids, the building blocks for protein molecules. This experiment (see the apparatus depicted below), and other similar experiments, have produced additional simple monomers — certain building blocks of life.  


 Critiques of Miller-Urey 

Subsequently, careful critiques of the Miller-Urey experiments and similar experiments created great doubt about their significance, though they are still taught in some high school textbooks as if they were scientifically sound. The atmosphere used in their experiments assumed a very energy-rich primordial atmosphere of methane, ammonia, and hydrogen, none of which would have been chemically stable in an early-Earth atmosphere. Studies of the early Earth’s atmosphere by NASA during the 1980s confirmed that the mix of atmospheric gases used in the groundbreaking Miller-Urey experiments was wrong. The journal Science summed up the discoveries in 1980 by noting, “No geological or geochemical evidence collected in the last thirty years favors an energy rich, strongly reducing primitive atmosphere (i.e., hydrogen, ammonia, methane, with no oxygen). Only the success of the Miller laboratory experiments recommends it.”2 Later articles put it equally bluntly — in 1995, Science stated that “the early atmosphere looked nothing like the Miller-Urey situation.”3 Again in 2008, an article in Science reported, “Geoscientists today doubt that the primitive atmosphere had the highly reducing composition Miller used.”4 

Atmosphere of the Early Earth 

There are good reasons to understand why the Earth’s early atmosphere did not contain high concentrations of methane, ammonia, or other reducing gases. Earth’s early atmosphere is thought to have been produced by outgassing from volcanoes, and the composition of those volcanic gases is related to the chemical properties of the Earth’s inner mantle and core. Geochemical studies have found that the chemical properties of the Earth’s interior would have been very similar in the past as they are today.5 But today, volcanic gases do not contain methane or ammonia, and are not generally reducing. Instead, an atmosphere dominated by carbon dioxide is preferred, but this poses a problem for prebiotic synthesis experiments, as prominent origin of life theorist David Deamer observed: “Carbon dioxide does not support the rich array of synthetic pathways leading to possible monomers, so the question arose again: what was the primary source of organic carbon compounds?”6


Another problem with Miller-Urey type prebiotic synthesis experiments is that when amino acids are synthesized from energy-rich gases, a racemic mixture of amino acids is created with 50 percent L-amino acids and 50 percent D-amino acids, sometimes called left-handed and right-handed. Proteins molecules created in living systems must have 100 percent L-amino acids. If there are any D-amino acids in the chain, it would prevent the chain of amino acids from folding up into the proper three-dimensional protein structures associated with this amino acid string, preventing it from performing its function. 

More Problems with Miller-Urey 

There are many additional problems with Miller-Urey-type research that seeks to identify plausible chemical pathways for the synthesis of proteins, DNA, and RNA molecules — the molecules of life. So drastic is the evidence against prebiotic synthesis of life’s building blocks that in 1990, the Space Studies Board of the National Research Council recommended a “reexamination of biological monomer synthesis under primitive Earthlike environments, as revealed in current models of the early Earth.”7 Because of these difficulties, many leading theorists have abandoned the Miller-Urey experiment and the “primordial soup” model it is claimed to support. In 2010, University College London biochemist Nick Lane stated the primordial soup theory “doesn’t hold water” and is “past its expiration date.”8 Instead, he proposes that life arose in undersea hydrothermal vents where water circulates through hot volcanic rock at the bottom of the ocean. But both the hydrothermal vent and primordial soup hypotheses face another major problem.

Matthew ch.5 KJV

Matthew5KJV:"And seeing the multitudes, he went up into a mountain: and when he was set, his disciples came unto him:


2 And he opened his mouth, and taught them, saying,


3 Blessed are the poor in spirit: for theirs is the kingdom of heaven.


4 Blessed are they that mourn: for they shall be comforted.


5 Blessed are the meek: for they shall inherit the earth.


6 Blessed are they which do hunger and thirst after righteousness: for they shall be filled.


7 Blessed are the merciful: for they shall obtain mercy.


8 Blessed are the pure in heart: for they shall see God.


9 Blessed are the peacemakers: for they shall be called the children of God.


10 Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven.


11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.


12 Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.


13 Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.


14 Ye are the light of the world. A city that is set on an hill cannot be hid.


15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.


16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.


17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.


18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.


19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.


20 For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.


21 Ye have heard that it was said of them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:


22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee;


24 Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.


25 Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison.


26 Verily I say unto thee, Thou shalt by no means come out thence, till thou hast paid the uttermost farthing.


27 Ye have heard that it was said by them of old time, Thou shalt not commit adultery:


28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.


29 And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.


30 And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.


31 It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement:


32 But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.


33 Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths:


34 But I say unto you, Swear not at all; neither by heaven; for it is God's throne:


35 Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King.


36 Neither shalt thou swear by thy head, because thou canst not make one hair white or black.


37 But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.


38 Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth:


39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.


40 And if any man will sue thee at the law, and take away thy coat, let him have thy cloak also.


41 And whosoever shall compel thee to go a mile, go with him twain.


42 Give to him that asketh thee, and from him that would borrow of thee turn not thou away.


43 Ye have heard that it hath been said, Thou shalt love thy But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;


45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust


46 For if ye love them which love you, what reward have ye? do not even the publicans the sam


47 And if ye salute your brethren only, what do ye more than others? do not even the publicans s


48 Be ye therefore perfect, even as your Father which is in heaven is perfect.
