At the end of this letter, the apostle Paul reminds the Galatians once again the reason he wrote in the first place: "Don't forget the gospel!" In other words, there is only one gospel, not many. It's common to hear people today say, "What really matters is not what you believe, but how you live." In this passage, Paul both deconstructs that mistake and also shows us how the gospel gives us the answer to our souls deepest (and most vulnerable) questions about worth, value, and significance.
