Galatians 2: 11-21 - The biggest problem we have is doing God's work in our own strength not in God's strength. Ray Ortlund reminds us that Christians today have all the advantages the early church had and that God put the book of Galatians in the New Testament to help them then, and us now, to embrace the magnitude of Christian faithfullness and calls us to examine our own faithfullness to Christ by examining the Paul's rebuke of Peter.
