Augustine of Hippo

By predestination God indeed foreknew that which he himself was going to do. Thus it was said, "He has made that which shall be." Furthermore, [God] can foreknow even those things that he himself does not do, such as whatever sins there may be. There are certain things that are sins and at the same time punishment for sins, so that it is written, "God delivered them up to a reprobate mind, to do those things which are not fitting." This is not the sin of God, however, but the judgment of God.
