Jesus is God
You take so many things out of context and twist what the Bible says to fit your own beliefs...Jesus was temporarily emptied of his independent use of his divine attributes (Phillipians 2:6-7) because he became flesh...he could still do miracles, he was still God, he just couldn't do divine things without his Father while he was human.
-In John 14:28, Jesus is talking about returning to a greater realm than Earth, he is not saying that the Father is God but he (Jesus) is not. "The comparison is only meaningful if they're already on the same plane and there's some delimitation going on. Jesus is in the limitations of the Incarnation...he's about to return to the Father and to the glory he had with the Father before the world began." (-The Case for Christ, which I would strongly encourage you to read.)
Read John 1:1 and 10:30 and tell me that Jesus is not God.
