"God became man" in Christian religion, but not in the Word of God.

1 Timothy 6:16 says about God that he "alone is immortal and who lives in unapproachable light, whom no one has seen or can see."

If Jesus had been God, no one would have seen him and he would never have died.

The Gospel of God teaches that God sent his Son to the world, not that "God became man" which he never did.
