Our Lutheran churches teach that those who have fallen after Baptism can receive forgiveness of sins whenever they are converted, and that the church ought to impart absolution to those who return to repentance. Properly speaking, repentance consists of these two parts: one is contrition, that is, terror smiting the conscience with a knowledge of sin, and the other is faith, which is born of the Gospel, or of absolution, believes that sins are forgiven for Christβs sake, comforts the conscience, and delivers it from terror. 6 Then good works, which are the fruits of repentance, are bound to follow.
Repentance, in other words, is not about "paying off" God or making some satisfaction for our sin. Repentance is recognizing the reality of our sin and turning to God in faith for His mercy. God reveals our sin through His Law; He forgives our sin and restores us to the right relationship with Him through His Gospel. While we affirm there is the fruit of repentance, the focus of the Gospel must be clear: our sins are forgiven only because of Christ. Our lives in Christ are lives of repentance, returning again and again to the fount and source of all mercy, our Savior.
Repentance should produce good fruit. These good fruit are what the commandments teach: prayer, thanksgiving, the confession of the Gospel, teaching the Gospel, obeying parents and rulers, and being faithful to one's calling. We should speak the truth. These fruit have God's command and should be produced for the sake of God's glory and command. They have their rewards also.
