Galatians 3:6-10

Even as Abraham believed God, and it was reckoned unto him for righteousness. Know therefore that they that are of faith, the same are sons of Abraham. And the scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand unto Abraham, saying, In thee shall all the nations be blessed. 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.
