How does the law point us to Christ?

In Romans 3:20, we learn that 'by the law is the knowledge of sin'. The law serves as a guide that highlights human inadequacy in achieving righteousness through our own efforts. It reveals God’s holy standard, and in doing so, it leads us to recognize our desperate need for a Savior. As indicated in Galatians 3:24, the law functions as a schoolmaster that brings us to Christ for justification by faith. Without the law, we would not understand the depth of our sin or the significance of Christ’s sacrifice. This makes the law an essential precursor to the acceptance of the gospel, as it sets the stage for the grace offered through Jesus.
