"To summarize quickly, open theism is, at root, a belief about the nature of the future. Open theism is not, as open theists repeatedly point out, a belief about God’s omniscience. Crudely stated, according to open theism God does not know the future because the future does not yet exist. This does not limit God’s omniscience because if the future does not exist then there is nothing for God to know. In short, the future is 'yet to be,' the future is 'open' and unfolding. The openness of the future in open theism is generally rooted in a libertarian account of human free will. Because humans have free will God does not know what exact future will unfold in the face of human choices. Thus, open theism is described as a relational view of God as God is waiting upon and responsive toward the free choices of individuals. God, being infinitely powerful and resourceful, will bring about God’s purposes for the world, but how exactly that future will unfold is to be determined. God is playing, so the metaphor goes, a chess game with humanity. God will win the game, that outcome is 'predetermined,' but the exact course of the game is an unfolding and relational process given the moves humans will make and how God opts to respond as a consequence."
