Some people object to the idea that God knows all events in advance of their happening. Such a view, some insist, deprives mankind of its essential freedom. Open theists or free-will theists, for example, insist that the future (at least in its specific details) is in some fashion “open.” Even God does not know all that is to come.
God is sovereign in creation, providence, redemption, and judgment. That is a central assertion of Christian belief and especially in Reformed theology. God is King and Lord of all. To put this another way: nothing happens without God’s willing it to happen, willing it to happen before it happens, and willing it to happen in the way that it happens. Put this way, it seems to say something that is expressly Reformed in doctrine. But at its heart, it is saying nothing different from the assertion of the Nicene Creed: “I believe in God, the Father Almighty.” To say that God is sovereign is to express His almightiness in every area.
God is sovereign in creation. “In the beginning, God created the heavens and the earth” (Gen. 1:1). Apart from God, there was nothing. And then there was something: matter, space, time, energy. And these came into being ex nihilo—out of nothing. The will to create was entirely God’s. The execution was entirely His. There was no metaphysical “necessity” to create; it was a free action of God.
God is sovereign in providence. Traditional theism insists that God is omnipotent, omniscient, and omnipresent—all powerful, all knowing, and everywhere present. Each assertion is a variant of divine sovereignty. His power, knowledge, and presence ensure that His goals are met, that His designs are fulfilled, and that His superintendence of all events is (to God, at least) essentially “risk free.”
God’s power is not absolute in the sense that God can do anything (potestas absoluta); rather, God’s power ensures that He can do all that is logically possible for Him to will to do. “He cannot deny himself,” for example (2 Tim. 2:13).
Some people object to the idea that God knows all events in advance of their happening. Such a view, some insist, deprives mankind of its essential freedom. Open theists or free-will theists, for example, insist that the future (at least in its specific details) is in some fashion “open.” Even God does not know all that is to come. He may make predictions like some cosmic poker player, but He cannot know absolutely. This explains, open theists suggest, why God appears to change His mind: God is adjusting His plan based on the new information of unforeseeable events (see Gen. 6:6–7; 1 Sam. 15:11). Reformed theology, on the other hand, insists that no event happens that is a surprise to God. To us it is luck or chance, but to God it is part of His decree. “The lot is cast into the lap, but its every decision is from the Lord” (Prov. 16:33). Language of God changing His mind in Scripture is an accommodation to us and our way of speaking, not a description of a true change in God’s mind.
