Of course, there is nothing inherently wrong with any of that. Christians are right - man does need God. Without God, man is lost; and God-less man has made an awfully terrible mess of the world.
At the same time, Christians rarely consider the possibility that God needs man just as much as man needs God. That without man, God might be a bit lost. That without man, God may not be motivated to do more than point at the external world and say, "You see? You see? You see?"
Without God, man is impoverished - but doesn't the same hold true in reverse? That without man, God is impoverished, too?
Man needs God. That is beyond argument.
Yet, God also needs man.
This immediately raises some crucial questions:
Why does God need man?
What does God need man to Be?
How can man meet or fulfill God's need?
Need here does not mean duty or obligation. At the core of this mutual, divine-human need is the freely offered supply of something in order to bring forth the manifestation of a desired state.
This something to be supplied is creativity.
Above all else, God needs man to be creative.
God is the Creator and He needs co-creators.
When Christians expand their standard formula of man's need of God by adding the simple equation of God's need of man, the divine-human revelation will begin to unfold and the creative transfiguration of the cosmos will begin.
