Charles Spurgeon Commentary Galatians 3:9-10

"So then they that are of faith are blessed with the faithful Abraham. For as many as are of the works of the law are under a curse: for it is written, Cursed is every one who continueth not in all things that are written in the book of the law, to do them." — Galatians 3:9-10 (ASV)

So then those who are of faith are blessed with faithful Abraham. For as many as are of the works of the law are under the curse:

All the people in the world who think themselves good, all the mere moralists, all those who, however amiable they may be, however excellent and religious they may be, are trusting to be saved by good works, are all under the curse, as surely as the drunkard, or the liar, or the swearer, is under the curse.
