What does the Bible say about God's law and commandments?

God's law serves multiple purposes, primarily to reveal sin and set the standard for righteousness. In Psalm 119, the psalmist calls on God to teach His statutes and commandments, which highlights an important distinction: to keep the law means desiring and cherishing it in our hearts, rather than just obeying it mechanically. The law points us to Christ, who is the ultimate law keeper and our substitute. He fulfilled the law on our behalf, demonstrating both God's justice and mercy, enabling us to walk in the path of His commandments with delight.
