What is the role of God's law in salvation?

The law's primary role is to expose sin, as stated in Romans 3:20: 'By the deeds of the law, there shall no flesh be justified in His sight.' It reveals our total inability to meet God's perfect standard and highlights our desperate need for a Savior. The law serves as a mirror reflecting our sinful state, demonstrating that we cannot earn justification through our actions. Instead, it drives us to rely on God's grace manifested in Christ, who fulfilled the law on our behalf and provides the only true basis for justification.
