Book Three, Chapter 14
Of Considering the Secret Judgments of God, That We be Not Puffed up With our Own Good Works

I stand astonished, and consider that the heavens are not pure in Your sight.  If in the angels You found depravity, and have not spared them, what will become of me?  Stars have fallen from heaven; and I, dust as I am, how can I presume?  They whose works seemed praiseworthy have fallen to the very lowest; and those that ate the bread of angels I have seen delighted with the husks of swine.  There is no sanctity, if You, O Lord, withdraw Your hand....Oh, how humbly and lowly ought I to think of myself; of how little worth, whatever good I may seem to have!
