We, indeed, ascribe both prescience and predestination to God; but we say, that it is absurd to make the latter subordinate to the former (see chap. 22 sec. 1). When we attribute prescience to God, we mean that all things always were, and ever continue, under his eye; that to his knowledge there is no past or future, but all things are present, and indeed so present, that it is not merely the idea of them that is before him (as those objects are which we retain in our memory), but that he truly sees and contemplates them as actually under his immediate inspection. This prescience extends to the whole circuit of the world, and to all creatures. By predestination we mean the eternal decree of God, by which he determined with himself whatever he wished to happen with regard to every man.
