If God did not arrange [the world] this way, then there must be an independent factor in the universe. And if there is such, one consequence and perhaps two follow. First, the doctrine of creation must be abandoned. A creation ex nihilo would be completely in God's control. Independent forces cannot be created forces, and created forces cannot be independent. Then, second, if the universe is not God's creation, his knowledge of it--past and future--cannot depend on what he intends to do, but on his observation of how it works. In such a case, how could we be sure that God's observations are accurate? How could we be sure that these independent forces will not later show an unsuspected twist that will falsify God's predictions? And, finally, on this view God's knowledge would be empirical, rather than an integral part of his essence, and thus he would be a dependent knower. These objections are insurmountable. We can consistently believe in creation, omnipotence, omniscience, and the divine decree. But we cannot retain sanity and combine any one of these with free will.
