In this Sermon, Pastor Sam of Harvest Liberty Lake Church explores the conflict between the apostles Paul and Peter in Galatians 2:11-14. The focus is on the implications of the gospel and the dangers of hypocrisy and the fear of man. The importance of accountability and humility is emphasized, as well as the endless grace of God despite repeated sins. Listeners are encouraged to reflect on their own lives and consider areas where they may need to align their actions with the truth of the gospel.
