The Apostle Paul's earliest surviving letter, Galatians gives its readers an insight into Paul's life as a Pharisee and persecutor, and the change brought about through his amazing conversion. Paul Barnett's enlightening commentary shows readers the apostle Paul's defense of the truth he now held to at any cost, and his heartfelt desire to protect the Galatian church from false teachers who sought to impose the old law-driven perspective on new Christians, both Jew and Gentile.
