What does the Bible teach about the role of the law in salvation?

The law serves several purposes, chiefly to highlight human sinfulness and our inability to achieve righteousness through our own efforts. Galatians 2:16 states, 'Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ.' This reveals that the law's role is not to save, but to demonstrate our need for a Savior. Furthermore, as stated in Galatians 3:23-24, it acts as a tutor to bring us to Christ, pointing us to the grace of God which is revealed in the gospel. Thus, the law highlights sin and drives us to the righteousness found in faith in Christ alone.
