that if you don't know with certainty you cannot jump into the nature of who Jesus is with absolute certainty

That I'm well aware of, but at the same time, correct advise.
That is part of the reason, that I'm relooking at this area.
Aim, to prove beyond doubt, who the Theos is.
Something for you to consider and you 'may' have a plausible answer for it?
If you say Jesus is the Word and he is covered a lot in the first 13 verses (?), the likes of - he came to his own and his own received him not = There, he would be flesh and then SUDDENLY, there is about face, he has now effectively gone back into the womb and become flesh at 1:14.
That to me makes zero sense whatsoever and grossly mess's with the flow.
1:14 imo, would be in place of 1:3 and the current 1:3 would be 1:4 and so on.
