The main idea:
Galatians defends the Gospel against every attempt to add human works to Christ, teaching that sinners are justified by faith alone through Christ’s finished work on the cross, and that this grace frees believers from legalism and licentiousness alike, empowering them by the Spirit to live in holy, unified love and to stand firm in that freedom.
