How does the law relate to sin according to the Bible?

In the biblical context, particularly in Romans, the law serves a critical purpose: it reveals sin and causes awareness of our inability to fulfill the law's demands. Romans 3:20 states that by the law is the knowledge of sin, highlighting that the law, while holy and righteous, can only expose our sinful nature. This function is essential as it drives us to seek salvation through grace alone, as our works cannot justify us. The realization that we are unable to meet the law's standards compels believers to trust in Christ, who fulfills the law on our behalf, resulting in justification and an empowered life through the Spirit.
