Paul started several churches in the province of Galatia and then moved on to other regions. Then he learned that some other people had gone to Galatia and were teaching the people that the gospel involved much more than Paul had told them. “Jesus is good,” they apparently said, “but you need to go further. You need to obey the Law that God gave his people. Faith is good, but you need the laws of Moses, too.”
Paul was furious! The people were making false accusations about him, trying to hijack the work he had done, and worst of all, leading the people away from Christ. Paul wrote a letter to explain what the gospel is. It has much to teach us today.
