"One thing they specially commend, that the blush of shame in the penitent is a severe punishment, which makes him more cautious for the future, and anticipates divine punishment, by his punishing himself. As if a man was not sufficiently humbled with shame when brought under the cognizance of God at his supreme tribunal. Admirable proficiency—if we cease to sin because we are ashamed to make one man acquainted with it, and blush not at having God as the witness of our evil conscience!"
