How does JEHOVAH separate sinner from Sinner.

 1John ch.5:16,17NLT"If you see a fellow believerd sinning in a way that does not lead to death, you should pray, and God will give that person life. But there is a sin that leads to death, and I am not saying you should pray for those who commit it. 17All wicked actions are sin, but not every sin leads to death."

The danger with the so called minor sins is that they are corrosive to the kind of character sincere Christians are attempting to cultivate,so the question is not whether this or that particular thought or act is disqualifying or not but whether this or that pattern of thinking and conduct causes me to more closely resemble my Savior and his God JEHOVAH or not. Every time we surrender to the flesh we become slightly weaker and every time we accept JEHOVAH'S Help and prevail over the flesh we become stronger and closer to our heavenly Father the Lord JEHOVAH, 

But there is a class of sin that can't be tolerated by JEHOVAH or his true church, John says don't pray for those sinning in this way,

John ch.5:16"...But there is a sin that leads to death, and I am not saying you should pray for those who commit it." 

Before there can be forgiveness there must come repentance and genuine repentance is not something that even JEHOVAH can impose on a sinner,

 1Samuel Ch.16:1NLT"Now the LORD said to Samuel, “You have mourned long enough for Saul. I have rejected him as king of Israel, so fill your flask with olive oil and go to Bethlehem. Find a man named Jesse who lives there, for I have selected one of his sons to be my king.”"

It is always a cause for sadness when one who made a fine start turns away from his vow and starts living in obstinate and open defiance of JEHOVAH'S Law but JEHOVAH is telling us that barring some evidence of genuine repentance the time will come when we Must harden our hearts, JEHOVAH'S Cause will not suffer regardless of how many choose to abandon it,they will be replaced by determined loyalists who will bring glory to JEHOVAH

JEHOVAH'S true church is identified by a determination keep itself free of community guilt by not tolerating gross sin in its ranks and definitely not among its teachers. 

1corinthians ch.5:12,13NIV"What business is it of mine to judge those outside the church? Are you not to judge those inside? 13God will judge those outside. “Expel the wicked person from among you.” d"

We are not sacralist who feel we have some mission to save the nation from itself through the installing of a Christian prince to impose God's law on the people.

We are the diplomatic mission of JEHOVAH'S Kingdom ,and we are eager to represent our sovereign in a worthy way,so we continually seek his unfailing help in remaining Holy individually and collectively
