For the preaching of repentance, or the call of the Gospel†: to reform repent,—when it truly penetrates into the heart, strikes the conscience with alarm, and is not a jest, but great terror, in which the soul feels its wretchedness and sins, and the wrath of God. While in this terror, the heart should again seek consolation, which takes place when we believe in the promise of Christ, that, through him, we receive remission of sin. The faith, which, in such fear and terror, cheers the heart and consoles it, receives and experiences remission of sin, justifies us and brings life; for this strong consolation is a new birth and a new life. This is simple and clear language; the pious know it to be true; we have examples in the church, showing that this applies to all the saints from the beginning, as in the conversion of Paul and Augustine.
(Henkel Translation, p. 168-169, † Here the word Gospel—like the first four books of the New Testament—includes both doctrines of Law-repentance and Gospel-remission of sin).
