In the middle of Galatians, Paul took a few chapters to discuss the law and its place in a believer’s life, even tracing it back to Abraham, Sarah, and Hagar. Beginning in Chapter 5, however, he is going to demonstrate what a believer’s life, under a new covenant of Grace, should look like in practice. Even more importantly than that, he will command believers to walk in the Spirit—doing so is the only way that they will be able to display the character of Christ.
