What is the role of God's law in teaching believers?

God's law plays a vital role in teaching His people by convicting them of sin and directing them toward righteousness. In Romans 3:20, it states that 'by the law is the knowledge of sin.' The law serves to expose our shortcomings and our need for a Savior. Furthermore, through God's law, believers learn to appreciate grace more fully as they recognize their inability to satisfy God’s righteous requirements on their own. God's law, therefore, is both a tool for conviction and a pathway to understanding the gospel, which fulfills the righteousness of the law in believers' lives through Christ.
