What is the purpose of repentance?

Repentance for salvation is a change of mind from unbelief to belief in Jesus (Acts 19:4; John 3:16-17; Ephesians 2:8-9). After salvation, repentance becomes about maturing in the faith through an exchange of sinful mindsets and behaviors for righteous mindsets and behaviors (Romans 6:2, 12, 18). For the believer, repentance from sins doesn’t make us more forgiven by God, but it does help us to express more fully our new identity in Christ.
