Why is God's law significant for understanding good works?

God's law serves as the foundation for defining what good works are and how they should be practiced. As seen in Romans 3:20, the law reveals sin, thus highlighting our need for grace and the necessity of good works. The commandments were given not just for obedience but to expose our shortcomings, demonstrating our reliance on God's mercy. Therefore, understanding God's law equips believers to pursue lives that align with His will, reflecting genuine faith in action and reliance on divine grace, rather than mere legalism.
