. . . The law of contradiction cannot be sinful. Quite the contrary, it is our violations of the law of contradiction that are sinful. Yet the strictures which some devotional writers place on “merely human logic” are amazing. Can such pious stupidity really mean that a syllogism which is valid for us is invalid for God? If two plus two is four in our arithmetic, does God have a different arithmetic in which two and two make three, or perhaps five?
The fact that the Son of God is God’s reason, for Christ is the wisdom of God as well as the power of God, plus the fact that the image in man is the so-called “human reason,” suffices to show that this so-called “human reason” is not so much human as divine.
Of course, the Scripture says that God’s thoughts are not our thoughts and his ways not our ways. But is it good exegesis to say that this means his logic, his arithmetic, his truth are not ours? If this were so, what would the consequences be? It would mean not only that our additions and subtractions are all wrong, but also that all our thoughts, in history as well as in arithmetic, are all wrong. If, for example, we think that David was King of Israel, and God’s thoughts are not ours, then it follows that God does not think David was King of Israel. David in God’s mind was perchance Prime Minister of Babylon.
To avoid this irrationalism, which of course is a denial of the divine image, we must insist that truth is the same for God and man. Naturally, we may not know the truth about some matters. But if we know anything at all, what we must know must be identical with what God knows. God knows all truth, and unless we know something God knows, our ideas are untrue. It is absolutely essential, therefore, to insist that there is an area of coincidence between God’s mind and our mind. One example, as good as any, is the one already used, viz., David was King of Israel.
