Our Lives Must Agree with the Gospel

We come on the scene here in Galatians 2 and stumble on the scene of the Apostle Paul confronting the Apostle Peter over the way he acted.
From our introductory study in Acts we must recognize that at no time did Peter disagree with the Gospel Paul proclaimed. Then the issue was a matter of practice in the life, and not a disagreement over the Gospel Paul and Peter preached.
I. Confrontation (v. 11-14)
II. Rationale (v. 15-21)
