“‘If he trespass against you seven times in a day, and seven times in a day turn again to you, saying, I repent; you shall forgive him’ (Lk. 17:4).
As the Searcher of hearts, the Lord knows that men are liable to very frequent trespass, and that, having fallen, they often rise up again; therefore He has given us the commandment to frequently forgive trespasses, and He Himself is the first to fulfill His holy word. As soon as you say from your whole heart, ‘I repent,’ you will be immediately forgiven.”
