Paul's letter to the Galatians is one of the most important books in the Bible. At stake is the very definition of the gospel itself. What is the gospel? What does it mean to be a Christian? Do you need to believe in all that supernatural and doctrinal stuff? Or is it enough to simply follow the ethical teachings of Jesus? Throughout the letter, Paul answers these, and many more, questions. In these first 5 verses, he lays out the two main themes that will dominate the rest of the letter. And if we hear what he's saying here, we can lay hold of the explosive power of the gospel for ourselves.
