 Second, the antitheist may argue, the free will defense violates divine omniscience. For if I possess libertarian freedom, then whether I decide to go to the concert tonight is neither under God’s direct control nor controlled by natural causes. And if that is the case then God has no way of knowing what I will decide. Like anyone, he can make a lucky guess: he may believe devoutly that I will decide to attend the concert, and that may turn out to be correct. But lucky guesses do not count as knowledge. Knowledge requires reasons, and God can have no satisfactory reason for his belief, if by “satisfactory” we understand what the infallible omniscience usually attributed to him would require — namely, a reason that guarantees correctness. Rather, like any observer, God must wait to learn what my decision will be in order to be sure of it. But then throughout the time prior to my act, God is not omniscient. There is a truth about the future that he does not know. Thus, the antitheist may conclude, the free will defense is in fact a failure. It exonerates God from direct responsibility for sin, but it does so only by surrendering part of God’s sovereignty, and by making him fail, as creator, to be omniscient.
