But we shall presently endeavor to show that we obtain remission of sin by faith alone (as the minor says,) and not through love. Our opponents have been trifling with these important things. They ask, whether the remission of sin and the infusion of grace are one change, or two. It seems impossible for these idle, ignorant men to treat these things properly; for, to have a real sense of sin and of the wrath of God, is not an unimportant or trifling subject; nor is the consciousness of the remission of sin a feeble consolation. Thus Paul says, 1 Cor. 15:56–57, “The sting of death is sin; and the strength of sin is the law. But thanks be to God who giveth us the victory through our Lord Jesus Christ.” That is, sin alarms the conscience; this is done by the law, which shows us the earnest zeal and wrath of God against sin; but through Christ we conquer.
How is this effected? When we believe—when our hearts are lifted up by the promises of grace through Christ, and rely upon them. Thus we prove, that we obtain remission of sins, by faith in Christ, and not by works; that is, God cannot be reconciled or his wrath appeased by our works, but Christ alone is the Mediator and Conciliator, for his sake alone is the Father merciful to us. (Henkel Translation, p. 171-172).
