In this section of Paul's letter, he gives a stern warning against defecting from the one true Gospel. He declares that Christ has graciously given Himself for our sins and delivered all professing Christians from this present evil age; and any works of the Law are unnecessary for salvation. False teachings that had risen in the Galatian churches compromised this core truth then, and even continue today as enemies of God's Church continue to question the divine origin of the Christian message, causing doubts and confusion among some believers. In chapter 2, Paul goes to Jerusalem with Barnabas and Titus to visit Church leaders who, in spite of some opposition in their midst, approved of Paul's message and his mission to the Gentiles.
