All the Fabrications that Jrsus is God came from John

And Thomas answered and said unto him [Jesus], My Lord and my God. John 20:28

I and my Father are one. John 10:30

God was manifest in the flesh... 1 Timothy 3:16
I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins. John 8:24

To counter the reluctance to accept the so called now Christianity John become more explicit that Jesus is God deviating from the mild implicit view of the other previous Gospels.
