529. It is very similar in the case of those who are by the Lord's doing in a state of good. If these by an act of the will and the intellect, that is, deliberately and of set purpose, refrain from one evil as being a sin, they refrain from all evils; and the more so, if they refrain from several evils. For as soon as anyone deliberately and of set purpose refrains from any evil as being a sin, he is kept by the Lord in the intention of refraining from the others. If therefore he does evil through ignorance or some overwhelming bodily desire, this is still not imputed to him, because he had not intended or set his mind on it. A person can achieve this intention, if once or twice a year he examines himself, and repents of the evil he finds in himself. This is not the case if he never examines himself. These facts make it plain who it is that does not have sin imputed to him and who it is that does.
