The Bible and Lutherans teach that repentance is an acknowledgment of sin and sincere regret for it. A repentant sinner also trusts that God will forgive sin for Jesus’ sake. Repentance is a condition of the heart without which no one can hope to be saved. Every truly repentant sinner is assured of God’s free and full pardon. Therefore, he or she will seek to forsake a sinful life and to live a holy life for God.
