Obviously your NOT as smart at you think you are, if you think they are saying the same thing, bugger 2 Thes 2 showing up AGAIN.
And the Word flesh existing became = became onto the scene and dwelt among us = Simples and not the word turning into flesh DRRRRR.
That has already happened, as per the childlike message in Luke's opener.
That is where the word = Eph 3:9
And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things -> (And God said and NOT Jesus said.)
And the word -> here Eph, flesh became = Luke.
But hey, lets us ignore the corrupted capital W's added in the word of truth eh 
The word = the word of God came down from heaven, resulting in the first ever of all kind, Jesus, other than Eph 3:9.
WHY do I say this = BECAUSE the Bible and the Spirit of Truth, says exactly that.
2 Cor 11:3,4 -
But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. (as per Luke)
For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with.
And sure enough, this began with the Mother of Harlots, the CC's somewhere around the 100's, which has led most of the Christians down this corrupted road.
Missing the narrow gate or falling off the narrow road.
Hence Jesus's words running True the form, FEW find it = Truth.
