It seems that if Jesus and the Father are One, they should know the same things, not two gods having different understanding. (This is an argument that my Muslim friend uses to claim Christians therefore believe in more than one god, and that being part human and part God, Jesus is therefore limited - thus not really God, since God can’t be limited.)
Matthew 24:26
