How do we know grace abounds over sin?

Romans 5:20 notes, 'Moreover the law entered, that the offense might abound. But where sin abounded, grace did much more abound.' This assertion underscores the sovereign grace of God, which overcomes all sin. The law exposed humanity's sinfulness, but God's grace is shown to be greater. Theologians argue that no matter how deep the depravity, God's grace is deeper still, effectively providing forgiveness and salvation to all who believe. This assurance comforts believers, for it emphasizes that grace is not only a remedy but a reign in the lives of those saved, enabling them to lead righteous lives free from sin's tyranny.
