Theism, as a way of conceiving God, has become demonstrably inadequate, and the God of theism not only is dying but is probably not revivable. If the religion of the future depends on keeping alive the definitions of theism, then the human phenomenon that we call religion will have come to an end. If Christianity depends on a theistic definition of God, then we must face the fact that we are watching this noble religious system enter the rigor mortis of its own death throes.
