Ever keep in exercise the principle of mercy, and be ready to forgive our brother on the first intimations of repentance, and asking forgiveness; and should we even forgive our brother, or even our enemy, before he repent or ask forgiveness, our heavenly Father would be equally as merciful unto us.
History of the Church, 3:383.
One of the most pleasing scenes that can occur on earth, when a sin has been committed by one person against another, is, to forgive that sin; and then according to the sublime and perfect pattern of the Savior, pray to our Father in heaven to forgive him also.
History of the Church, 6:245.
To the iniquitous show yourselves merciful. . . . Beware, be still, be prudent, repent, reform, but do it in a way not to destroy all around you. I do not want to cloak iniquity—all things contrary to the will of God, should be cast from us, but don't do more hurt than good, with your tongues—be pure in heart. Jesus designs to save the people out of their sins. . . . I want the innocent to go free—rather spare ten iniquitous among you, than condemn one innocent one. "Fret not thyself because of evil doers." God will see to it.
History of the Church, 5:20–21.
