Such things they did imagine, and were deceived: for their own wickedness hath blinded them.
All Commentaries on Wisdom of Solomon 2:21 Go To Wisdom of Solomon 2
Augustine of Hippo
AD 430
The third way in which sin itself is also the punishment for sin can be seen in the one who says, "I do the evil that I do not want to do." To this third type also belong all those evil actions one does through ignorance, believing them not evil or even good. In fact, blindness of heart, if it were not a sin, would be unjustly reproved, and yet it is reproved justly where it says, "Blind Pharisee!" as well as in a great many other passages of the Word of God. Moreover, if blindness itself were not a punishment for sin, it would not be said, "Their wickedness has blinded them." And if this did not happen by a judgment of God, we would not read, "Their eyes are darkened so they would not see; he weakens their backs forever." Indeed, who would blind his heart by his own choice, when no one would want to be blind in his body?
