Why is repentance necessary in the Christian faith?

Repentance is a foundational doctrine within the Christian faith; it serves as a necessary response to the gospel. Jesus and His forerunner, John the Baptist, emphasized repentance as the initial step towards entering the Kingdom of God. The act of repentance involves recognizing our sinful state, feeling genuine sorrow for our offenses against God, and turning away from our previous ways to embrace faith in Jesus Christ. It is vital because it indicates a heart transformation that aligns with the grace God provides in Christ, through which we find forgiveness and restoration. In essence, repentance acknowledges our need for His mercy and grace, enabling us to partake in the fullness of salvation.
