How does God's grace operate through the law?

Romans 5:20 notes that the law was introduced to make offenses increase, demonstrating humanity's sinfulness and the necessity for grace. The law acts as a mirror, revealing our shortcomings and the inevitable judgment that results from our transgressions. However, this exposure to sin is not without purpose; it underscores our desperate need for a Savior. Through the fulfillment of the law by Christ, we are offered grace and justification. Rather than condemning us, the law leads us to recognize the exceeding greatness of God's grace as we see the great gap between our sin and the righteousness found in Christ. Consequently, grace reigns where the law had initially pronounced condemnation, revealing the redemptive plan woven through Scripture.
