The Promise and the Law

The Apostle Paul just showed these confused Galatians precisely why they should not have listened to the Jewish false teachers. (1) The truth was obvious in their experience. They received the Spirit of God by faith when they believed. (2) The truth was obvious in the Scriptures because Abraham believed God and He counted it for righteousness. (3) The truth was obvious because someone had to take away the curse of the Law. Now, Paul tackles the difference between the covenant and the Law.
I. Covenants cannot change (v. 15-18)
II. Two Questions and a conclusion (v. 19-29)
