"Many people, when brought to a reconciliation with others, say that they forgive, but they continue to hold malice, continue to suspect the other party, continue to disbelieve the others sincerity. This is sin, for when a reconciliation has been effected and when repentance is claimed, each should forgive and forget, build immediately the fences which have been breached, and restore the former compatibility. "
