What does the Bible teach about the law and its purpose?

Galatians 3:24 explains that the law was our schoolmaster to bring us to Christ, highlighting its role in exposing sin. The law is holy and good (Romans 7:12) but powerless to save because of the weakness of the flesh (Romans 8:3). Through the law, we see our transgressions and recognize our need for a Savior. The purpose of the law is not to provide salvation but to direct us to Christ, who fulfills the law and offers grace to those who cannot achieve righteousness on their own, as seen in both Old and New Testament teachings.
