Why is understanding true repentance important for Christians?

True repentance, as outlined in Acts 17:30, requires a turning away from one's former beliefs and notions about salvation, which may rely on personal efforts or religious traditions. Christians are called to recognize false strongholds in their lives—concepts that place confidence in anything apart from Christ’s atoning work. Repentance is not merely an acknowledgment of sin but a radical transformation that occurs through the Holy Spirit’s work in the heart, enabling one to see the complete sufficiency of Jesus' sacrifice. This understanding helps prevent believers from relying on their efforts and instead leads them to trust wholly in the grace of God for salvation.
