It’s always awkward when a fight breaks out at the church potluck, but what if the two parties are apostles? This is the rumble in the New Testament church. Because Paul is faithful to publicly confront Peter, and Peter is faithful to repent, the gospel continued to thrive. We learn that the gospel—the truth about Jesus’ life, death and resurrection—is not only something to believe, but something to live. It even affects the people we eat with, and even the apostles were not above stumbling.
