In Galatians 2:17-21, Paul reminds us that we are justified not by law-keeping, but by faith in Christ, and what this means for our practical, everyday living. If we, like Paul, renounce law-keeping as a means of salvation and trust in Christ alone, then we are dead to the curse and burden of the law, alive to God, and living under the good, wise, and gracious reign of King Jesus, who loves us and gave his life for us. Living out of that identity, Paul has all the motivation in the world to pursue holiness.
