What should the Christian life look like? What vision does Scripture cast for living as a follower of Christ? The New Testament scholar Jarvis Williams considers how Paul's letter to the Galatians can inform our understanding of the Christian life here and now as well as into eternity. What emerges from this careful study is a multifaceted vision of God's saving action in Jesus Christ for both Jew and Gentile, in both the vertical relationship between God and humanity as well as the horizontal relationships among people--with cosmic ramifications. Through Paul's instructions and Williams's interpretation, Christians can learn the importance of walking by the Spirit.
