God moves in himself and he finds rest in himself. God is the resolution of God. All permanent being must be incorporated into God, as there is no salvation without him. Still what is so important about us transient beings is we are very vulnerable and need that permanent one. That permanent one has a need to save and to love, to be born through us just as we must be born in him. God and the world fullfil each other, according to Whitehead. I see creation as something bleeding fourth from the sons heart, being born from that Divine love that the Trinity is. all things were made from nothing and this nothing could be nothing but an expression of that which was before creation was since God creates all out of his own self. or we could say that this nothing is like in the Jewish Kabbalah where god Empties himself in order to create. So in the son there is both The Emptiness and fullness of God. therefore I believe it is important to recognize the son's Humanity as something Universal and Cosmic and before this fleshly Humanity.
As I read the other day - God Wills both God and man. It makes sense otherwise why would the Son of God be fully God and fully human? But too many try to make the son of God's Humanity into some kind of minor part of him that he just recently became. This is just one way that humans try to alienate themselves from God. They try to rid Jesus Christ of his Humanity. But that would alienate us from God.
