What does the law reveal about sin?

As Romans 3:20 states, the purpose of the law is to give knowledge of sin, demonstrating that no one can achieve righteousness through their own efforts. The law acts as a mirror, showing us our sinful nature and inability to fulfill its demands, as highlighted in Galatians 3:24, where it serves as a guardian until Christ came. This understanding strips away any self-righteousness and leads us to the conclusion laid out in Romans 7:24, where Paul expresses the despair of the law and gratitude for Jesus Christ, the only one who can deliver us from sin and death. Therefore, the law ultimately drives us to Christ, revealing our need for His saving grace.
