Have you ever invested time and energy into something, only to have someone else come along and derail all you've worked for? That's the situation the Apostle Paul faced with the churches in Galatia. He brought the message of Jesus Christ—the gospel—to them. But false teachers slipped into these churches, claiming that the gospel Paul preached wasn't enough. They told the Galatians faith in Christ alone could not secure their salvation and sanctification. But Paul corrects this false teaching, reminding us that we are free in Christ and that a "Jesus plus" gospel is no gospel at all.
