Paul went from violently persecuting Christians to preaching the very faith he tried to destroy — so how do we know he wasn't just reacting against his past?Paul went from violently persecuting Christians to preaching the very faith he tried to destroy — so how do we know he wasn't just reacting against his past? In this message from Galatians 1:18–24, Dr. John examines Paul's second defense of the true gospel: that what he preached was not his own invention, but the one unified message agreed upon by all the apostles from the very beginning.

No Compromise: The book of Galatians was written because the gospel was under attack — and it still is today. From false teachers in ancient Galatia to the distortions we encounter in our own time, the battle over the heart of the Christian faith has never stopped. Join Dr. John for this four-part series as he works through one of Scripture's most urgent letters, asking what the true gospel is, where it comes from, and why getting it right changes everything.
