In this passage from Galatians, Paul expands on the idea that grace, not Law, is the foundation and center of the Christian life. He explains that while the Law restrains and exposes sin, it does not and cannot save from sin. The Law points us to our need for grace and a perfectly righteous Savior. Once we have placed our faith in Christ, our greatest responsibility is to abide in and depend upon him to transform our hearts, allowing us to walk in a righteousness that the Law could not give.
