What does the Bible say about living under the law?

In Galatians, the Apostle Paul warns against returning to the law after having known Christ. The law cannot save; it leads to bondage, and as believers, our liberty and righteousness come solely through faith in Jesus Christ. Paul emphasizes that our hope should be in Christ, who fulfills the law perfectly on behalf of His people, not in our own ability to keep the law. Once Christ came, the law served its purpose as a tutor that pointed us to Him, and now we live by the Spirit, which teaches us to walk in faith and love rather than by adherence to the law.
