On the role of the "Logos/prototokos" in the originating of the creation.

 John Ch.1:3NIV"Through(dia) him all things were made; without him nothing was made that has been made."

Colossians Ch.1:15,16KJV"Who is the image of the invisible God, the firstborn of every creature: 16For by (en)him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by(dia) him, and for him: "

 Proverbs Ch.8:22NAB"The LORD begot me, the first-born of his ways, the forerunner of his prodigies of long ago;"

Proverbs Ch.8:30NAB"Then was I beside him as his craftsman, and I was his delight day by day, Playing before him all the while,"

The Holy scriptures NEVER use prepositions like "en" and  "dia" in connection with JEHOVAH'S Role in the originating of the creation. Instead we read statements like this . 

Acts Ch.4:24NIV"When they heard this, they raised their voices together in prayer to God. “Sovereign Lord,” they said, “you made the heavens and the earth and the sea, and everything in them."

Genesis Ch.14:19NIV"and he blessed Abram, saying, “Blessed be Abram by God Most High, Creator of heaven and earth."

Revelation Ch.10:6NIV"And he swore by him who lives for ever and ever, who created the heavens and all that is in them, the earth and all that is in it, and the sea and all that is in it, and said, “There will be no more delay!"

Revelation Ch.4:11NIV"Thou art worthy, O LORD, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created."

Note nary an "en" or a "dia" in sight,note also that it is ONLY of the God and Father of Jesus the Lord JEHOVAH are such statements EVER Made. That is because the prepositions "en" and " dia" indicate instrumentality or an intermediary role. Thus the one referred to by these prepositions would not be the source of the authority or resources that made the creation possible but merely the instrument of this source.

E.g Matthew Ch.7:13NIV"“Enter through(dia) the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through(dia) it."

it is not the gate that is doing the entering it is instrument by which the entering is accomplished.

Hebrews Ch.1:1NIV"In the past God spoke to our ancestors through(en) the prophets at many times and in various ways, "

Thus it was JEHOVAH who was revealing his will but the prophets were his instruments.

Likewise at John Ch.1:3 and colossians 1:16 it is the God and Father of the Logos/Prototokos who is accomplishing the originating of his creation. His Logos/prototokos is his instrument.
