The apostle inquires how they could be so foolish as to renounce the Gospel of Christ and turn back to the law, after having heard, received, and suffered so much for the Gospel, Gal 3:1-5. Asserts the doctrine of justification by faith, on the example of Abraham, Gal 3:6-9. Shows that all who are under the law are under the curse, from which Christ alone redeems us; and the promise made to Abraham comes to the Gentiles who believe, Gal 3:10-14. For the covenant is not by the works of the law, but by promise, Gal 3:15-18. The law was given to show the sinfulness of sin, and to act as a schoolmaster till Christ should come, Gal 3:19-25. It is by faith only that any become children of God, Gal 3:26. And under the Gospel, all those distinctions which subsisted under the law are done away; and genuine believers, whether Jews or Gentiles, bond or free, are one in Christ Jesus, and accounted the genuine children of Abraham, Gal 3:27-29.
