What does the Bible say about the relationship between faith and repentance?

The relationship between faith and repentance is vital to the Christian faith. Acts 20:21 speaks of testifying both to Jews and Greeks of repentance toward God and faith in our Lord Jesus Christ, showing that both are essential components of salvation. Repentance is the recognition of our sinful state and turning away from sin, while faith is the trust we place in Christ for salvation. They occur simultaneously as part of the transformation brought about by the Holy Spirit, and neither can exist without the other in the life of a believer, as they are both gifts from God.
