What does the Bible say about the law being a schoolmaster?

The law serves as a schoolmaster in that it exposes sin and illustrates our inability to achieve righteousness through our own efforts. In Galatians 3:24-25, Paul emphasizes that before faith came, we were kept under the law but now that faith has arrived, we are no longer under its authority. This indicates that while the law was essential for illustrating our need for Christ, it was never intended to serve as our means of justification, as no man can be justified by the law before God (Galatians 3:11). The purpose of the law was always temporary, to prepare us for the promise that comes through faith in Jesus Christ.
