Being a Christian means first, believing the gospel, and second, letting your belief in the gospel take such a deep root that everything in your life is then shaped by the gospel. Paul here confronts Peter, because Peter was not walking "in step with the truth of the gospel," and invites us to a life of consistency in which everything in our lives flows from and is shaped by the gospel.
Application Questions:
1. Why does Paul confront Peter? How does Peter undermine the gospel with his actions?
2. What does it mean to walk "in step with the truth of the gospel"? How does this relate to gospel-consistency and hypocrisy?
3. How can the power of the gospel confront fear and idolatry in your life?
