Repentance is truly feeling sorry for the sin in your past, and having the goal to never do it again. It is making a decision to turn away from evil and to serve God. Repentance is one of the things needed to receive the forgiveness of sins. (Mark 2:17; Luke 15:10; Luke 24:46-47; Acts 3:19; Romans 2:4; 2 Corinthians 7:10; 2 Peter 3:9; Ephesians 4:22-24; Revelation 3:19.)
