Galatians 2 concludes with a story about Paul confronting Peter in his hypocrisy followed by a dense explanation of a core tenet of Paul’s theology: justification by faith. Galatians 2 and Romans 3 are the clearest and most compact explanations of justification by faith in all of Scripture. We will spend at least two weeks on this because it is such an important doctrine, not only for understanding Paul but for understanding the death and resurrection of Jesus, its implications, and what that means for us today.
