How do we know forgiveness is possible through Christ?

Forgiveness through Christ is a foundational tenet of faith in sovereign grace theology. In 2 Samuel 12:13, we see that God, through Nathan the prophet, declares that David's sin is put away, illustrating the powerful ability of God to forgive. This forgiveness is made possible through the atonement of Jesus Christ, whose blood serves as the ultimate sacrifice for our sins. The doctrine of imputation teaches that our sins are credited to Christ, and in exchange, His righteousness is granted to us. This means that God can justly forgive us while remaining true to His nature, demonstrating both justice and mercy.
