Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going back to God...
John 13:3
I don't see a reasonable way to interpret the Gospel of John to say that #yeshua is not God and didn't exist before his conception in Mary. Yeshua existed before Creation, created everything, is God, was God, came from God, and returned to God. I get that this is difficult to understand, but insisting that there is no way to reconcile these apparent discrepencies shows an inability (at best) or unwillingness (at worst) to think outside one's own box.
Also notice that this thought is echoed by Paul in Ephesians 4:8-10. I think that's deliberate and dramatically contradicts how many people interpret Paul's words.
