You don't need to BE God the Father to have foreknowledge or to perform miracles. To call Jesus God is to commit the original sin. That is to call him intrinsically better than you, or to call yourself intrinsically of less value or less worthy than your neighbor. Its through sin with words and deeds we defile ourselves. Yes Christ is our example, our lord & our guide, but he is also our brother through baptism of Holy Spirit. Only through Christ may we come to the Father with righteousness and as sons of God. There is no proof that Jesus is God, but there is much proof to the contrary, one being he said the Father is his God, another being that he was killed, another that he called himself the son of man. Foreknowledge is available to us all, and this is proof of God himself because it is one of many gifts of the Spirit.
