"Col 1:16 ........Do you accept that Christ is involved in the creation of everything ?"

Literally, as in hands on, according to the Bible Truth = NO.
The Jesus to be, was the God and Fathers motivation you might say, for him to create all things for this future one, alone and by himself.
In the mind and plans of the God and Father, the Jesus to be was the firstborn of creation, in the mind of God right where all our creations begin.
The Jesus to be, was the beginning of the creation of God, in him Rev 3:14, 13:8 etc.


who is the image of the invisible God, first-born of all creation,
because in him (for this reason, 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 through him, and for him:

Isa 44:24 - Thus saith Yehowah, thy redeemer, and he that formed thee from the womb, I Yehowah that maketh all things; that stretcheth forth the heavens alone; that spreadeth abroad the earth by myself;

Psa 33:6,9 - By the word of Yehowah were the heavens made; and all the host of them by the breath of his mouth.
For He spoke, and it was done; He commanded, and it stood fast.

"through him" context;

Original Word: διά

Phonetic Spelling: (dee-ah')
Definition: through, on account of, because of
Usage: (a) gen: through, throughout, by the instrumentality of, (b) acc: through, on account of, by reason of, for the sake of, because of.-> The future Jesus to be born from Mary = the meaning of -> "because in Him".

The 1st Adam was in God's image, likewise the 2nd Adam.

Now lets not leave out an important part of Col;
1:18 - And he is the head of the body, the church: who is the beginning, the firstborn from the dead; so that in all things he might have the preeminence.

Now we see the God and Fathers plans fulfilled and Jesus Now has literal and physical preeminence, where prior it was a plan to be.
NO literal/physical pre-existing Jesus in anyway shape or form, shows up in these Col verses.

John 17:17 - Sanctify them by Your truth. Your word is truth.
