How do we know that God's mercy is greater than our sin?

The gospel powerfully illustrates that where sin abounds, grace abounds even more (Romans 5:20). The outcome of the law—our realization of sin—does not end with condemnation but leads to the revelation of God’s mercy through Jesus Christ, who bore the penalty for our transgressions. It is emphasized that believers are no longer under the law's condemnation but are justified by faith in Christ's atoning sacrifice. In essence, the broken law reveals our sin, but the gospel reveals our Savior, who fulfilled the law and offers us grace beyond measure. Therefore, through faith in Christ, the repentant sinner is assured of full forgiveness and reconciliation with God, showcasing the vastness of God’s mercy.
