"So you also, when you have done all that is commanded you, say, `We are unworthy servants; we have only done what was our duty.'"

Luke 17:5-10

For the devil may tempt the good, but he cannot find rest in them; for he is shaken violently, and upset, and driven out, now by their prayers, now by their tears of repentance, and now by their almsgiving and similar good works.

- St. Bruno
