Why is the law called a schoolmaster?

The law is referred to as a schoolmaster in Galatians 3:24, indicating its role as a guardian or tutor leading God's people to Christ. Just as a schoolmaster oversees a child's education and behavior, the law instructs us in God's holiness and reveals our moral failures. It serves to protect us from the dangers of false belief and idolatry, urging us to seek refuge in Jesus. The law thus has a preparatory role, enabling us to understand our need for redemption and guiding us to the grace found in Christ, who is the ultimate fulfillment of the law.
