Apparently you did not read that Jesus could do nothing of himself, except what he saw the Father do.
If the Father did not heal and raise people from the dead and cast out devils, and die on a cross, and be resurrected from the dead, then Jesus, the Son would not either, for as Jesus says, he can do nothing of himself. It is because he is not fully vested as a God. After he was resurrected and given exhaltation, he became equal unto the Father. Until that happened God the Father remained greater than he was, that is per Jesus, not JS.
Jesus was divine by the time he came to earth, but not fully vested. After his earthly experience he was fully God.
I read it---it doesn't say what you say it does. What y9u fail to understand is that Jesus came to show the Father to the world, not Himself. We go through Jesus to God. God is the goal. God is the destination, Jesus is the journey. Jesus was exalted before He became a man, and He remained so. He lived in the presence of God before, during and after.
