Galatians 2:11-14

v11-12: One reason why Christians might "falter in fulfilling their duty to God" is because of a "desire to please people."  Is this something which you are prone to?

v13-14: Peter's reluctance to eat with the Gentiles undermined "both the truth of the gospel and the peace of the church." Peter believed that the death of Christ had destroyed the wall of hostility that divided Jew and Gentile, but his behaviour did not match his belief. This is a reminder to us whose faith is in Jesus that how we live really does matter.
