Def: Open Theism

From Reclaiming the Mind:

Open Theism, also referred to as “free will theism” and “openness theology,” is the belief that God does not exercise meticulous control of the universe but leaves it “open” for humans to make significant free will choices that impact their relationships with God and others. A corollary of this is that God has not predetermined the future. Open Theists further believe that this would imply that God does not know the future exhaustively.

Among proponents of this view are Gregory Boyd, John Sanders, and Clark Pinnock.
