Why is the law considered our schoolmaster?

In Galatians 3:24, the Apostle Paul refers to the law as a schoolmaster, implying that its purpose is to instruct and guide us to Christ. It exposes our sinfulness and drives us to recognize our helplessness, enabling us to appreciate the grace offered through faith in Christ. Rather than providing salvation, the law helps us to understand the weight of our sin and the beauty of Christ's redemptive work. Once we place our faith in Christ, we are no longer under the law as our tutor, but we inherit the promises of God through faith.
