How do we know that God's mercy is extended to sinners?

The assurance of God's mercy towards sinners is firmly rooted in the biblical tradition, as evidenced by the narrative of David's sin and subsequent restoration. When Nathan confronted David, it was a profound act of mercy that led David to recognize his sin. His heartfelt confession, 'I have sinned against the Lord,' was met with God's promise of forgiveness, demonstrating that God is both just and merciful. The doctrine of God's grace posits that no sin is too great to be forgiven when one genuinely repents. David became a living testimony of how God extends mercy, not only to him but to all who earnestly seek His grace. The continuity of this message throughout scripture reaffirms that God actively desires to restore sinners to fellowship with Him.
