But even the failure of their own light does not work repentance: they gnawed their tongues from their pain. Here is remorse and suffering. They are “unto themselves” (as the Book of Wisdom describes the Egyptians) “more grievous than the darkness” (Wis. 17:21); but there is no softening or humbling of themselves, no turning to God. They still love what God hates, and hate what He loves, for they blasphemed God, &c., and repented not of their works. Such is the wretched state of the world-power in the day when retributive evil overtakes it — darkness, pain, and inability to repent. Is it not a picture of the ultimate state of all sin? It is not a vast world-power alone which exhibits pain and confusion like this. It is to be seen over and over again in men and nations. The power of evil comes home and robs men of their accustomed guides. They are brought into darkness and trouble; the throne where the master-power of worldliness sat is cast down; the evil passion which was the unifying power of their life is deprived of the field of its power; then follows exasperation, anger at defeat, readiness to accuse others, but no blame of self, no repentance.
