The Relationship between Forgiveness and Repentance

Authentic forgiveness is a mutual recognition that repentance is genuine and reconciliation has been achieved. Without repentance, authentic forgiveness offered by the victim cannot be consummated because the victim can only extend a forgiving heart, which indeed demonstrates a love of one’s neighbor and enemy.
 
Jesus’s cry from the cross, “Father, forgive them, for they do not know what they are doing” (Luke 23:34), has often been misinterpreted to mean that he requires no repentance from sinners. But Jesus’s words echo the Old Testament practice of sacrifice for unintentional sin (see Num 15:27–31). His words confirm that his death is a once-and-for-all sacrifice to offer divine forgiveness for those people who act wrongly in ignorance. Nevertheless, this wrongful act in ignorance does not mean that there is no requirement of repentance.
 
In Acts 3:13–19, Peter stresses that people who deny God in ignorance also need to repent. To those who denied, rejected, or even killed Jesus, Peter said, “Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord” (Acts 3:19). Luke describes how Jesus, after his resurrection, reminded the disciples that everything written about him in Israel’s Scriptures must be fulfilled (Luke 24:44–46) and then authorized them to go to all nations to preach “repentance for the forgiveness of sins” (Luke 24:47). In obedience to this commission, Peter, filled with the Holy Spirit, preached powerfully about the gospel of repentance for the forgiveness of sins: “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins” (Acts 2:38). Repentance is essential for God’s forgiveness of sin and for salvation.
 
Repentance is indeed a necessary response to divine forgiveness and the salvation offered by Jesus. This is crucial because when disciples are called to follow Jesus to embody forgiveness, they will consider how repentance is associated with forgiveness in Jesus’s eyes. Many people tend to trivialize victimization by ignoring the claims of victims if they interpret what Jesus does for us as “cheap grace”—to use Bonhoeffer’s term. Cheap grace must be rejected because the forgiveness offered by Jesus was very costly—indeed, it cost Jesus his life. And Jesus takes very seriously the offenses that human beings commit against God and against one another, and he requires that sinners repent.
