When Paul and Barnabas were sent out on their first missionary journey, they learned a hard truth: the good news isn't always good news to the people who hear it. In fact, these 2 leaders in the early church found out the whenever they shared the goods news, they ticked somebody off! What they learned at the end of the journey helped them deal with that tension. It's the same thing we need to help us deal with the "no win" situations the gospel can place us in.
