"If God exists outside of time—not in time, but timeless and eternal—what would that mean about God's nature? God would never 'lose' the past or anticipate the future. God would not need to know the future, because to a timeless God, there would be no future. Everything would be ever-present in one timeless moment. But how could a timeless God relate to human beings?"
