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.
