Does God know the future? Or is the future unknowable to even God? Open theists believe the search for biblical answers will spark a new Revolution. Are they right? Arguing that God interacts with his creatures spontaneously, the controversial new movement known as "open theism" has called classic church theology up for reexamination. Confronting this view, classic theists maintain that God has complete foreknowledge and that open-theist arguments are unorthodox. Each view has implications for our vision of the future and of God's dealings with humanity.
