How do we know the concept of repentance is true?

The concept of repentance is deeply rooted in Scripture, as illustrated by Peter's confession in Luke 5:8. When confronted with the holiness of Christ, Peter acknowledged his sinful nature, a key aspect of true repentance. Romans 2:4 states that it is the goodness of God that leads us to repentance, highlighting that an understanding of God’s grace often follows our recognition of our sins. This theme of repentance resonates throughout Scripture, indicating that acknowledging our unworthiness is essential in our relationship with God, as it opens the door to receiving His mercy and forgiveness.
