Paul was desperate for his new brothers and sisters in Christ who were being persuaded to move away from Christ for their further salvation. Paul took to helping them see that his apostleship was not of a human origin (Gal. 1:1), nor his gospel (Gal. 1:11-17). He received both in one life-changing event, as he journeyed to Damascus to drag any errant Jews who had turned to the false Messiah Jesus back to Jerusalem to be imprisoned (Acts 9:1-6). In the heat and passion of that determined journey, Paul was visited and commissioned by the resurrected Christ! This is when the gospel was revealed to him. It was that divinely originated gospel that Paul fought to defend for the sake of the Galatian believers.
