Repentance is no more a meritorious work than its counterpart, faith. It is an inward response. Genuine repentance pleads with the Lord to forgive and deliver from the burden of sin and the fear of judgment and hell. It is the attitude of the publican who, fearful of even looking toward heaven, smote his breast and cried, “God, be merciful to me, the sinner!” (Luke 18:13). Repentance is not merely behavior reform. But because true repentance involves a change of heart and purpose, it inevitably results in a change of behavior.
