“We have elsewhere observed, that forgiveness of sins never can be obtained without repentance, because none but the afflicted, and those wounded by a consciousness of sins, can sincerely implore the mercy of God; but we, at the same time, added, that repentance cannot be the cause of the forgiveness of sins: and we also did away with that torment of souls—the dogma that it must be performed as due. Our doctrine was, that the soul looked not to its own compunction or its own tears, but fixed both eyes on the mercy of God alone. Only we observed, that those who labour and are heavy laden are called by Christ, seeing he was sent ‘to preach good tidings to the meek;’ ‘to bind up the broken-hearted; to proclaim liberty to the captives, and the opening of the prison to them that are bound;’ ‘to comfort all that mourn.’ (Mt. 11:28; Is. 59:1; Luke 4:18) Hence the Pharisees were excluded, because, full of their own righteousness, they acknowledged not their own poverty; and despisers, because, regardless of the divine anger, they sought no remedy for their wickedness. Such persons neither labour nor are heavy laden, are not broken-hearted, bound, nor in prison. But there is a great difference between teaching that forgiveness of sins is merited by a full and complete contrition (which the sinner never can give), and instructing him to hunger and thirst after the mercy of God, that recognizing his wretchedness, his turmoil, weariness, and captivity, you may show him where he should seek refreshment, rest, and liberty; in fine, teach him in his humility to give glory to God.”
