So the law is holy, and the commandment is holy and righteous and good. Did that which is good, then, bring death to me? By no means! It was sin, producing death in me through what is good, in order that sin might be shown to be sin, and through the commandment might become sinful beyond measure.-Romans 7:12,13
Why have we thought it worth while to mention this? For this reason, because, as the law is not an evil when it increases the lust of those who sin, so neither is death a good thing when it increases the glory of those who suffer it, since either the former is abandoned wickedly, and makes transgressors, or the latter is embraced for the truth’s sake, and makes martyrs. And thus the law is indeed good, because it is prohibition of sin, and death is evil because it is the wages of sin; but as wicked men make an evil use not only of evil, but also of good things, so the righteous make a good use not only of good, but also of evil things. Whence it comes to pass that the wicked make an ill use of the law, though the law is good; and that the good die well, though death is an evil.
-Augustine, City of God xiii.5
