Ambrose of Milan

Sin abounded by the Law because by the Law is the knowledge of sin, and thus it began to be injurious to me to know that which through infirmity I could not avoid; it is good to foreknow in order to avoid, but if I cannot avoid, to have known was injurious. Thus the effect of the Law was changed to me into its opposite, yet by the very increase of sin it became useful to me, because I was humbled. Wherefore David also said, It is good for me that I have been humbled.
