Pardon and forgiveness of sins is obtained by genuine repentance, confessing and forsaking of sins. We are justified by faith in the Lord Jesus Christ (Romans 5:1). John the Baptist preached repentance, Jesus proclaimed it, and the Apostles emphasized it to both Jews and Gentiles (Acts 2:38; 11:18, 17:30).
The word “repentance” comes from several Greek words which mean: change of views and purpose, change of heart, change of mind, change of life, to transform, etc.
Jesus said, ”…except ye repent, ye shall all likewise perish” (Luke 13:3).
Luke 24:47 says, “And that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem.”
