Galatians Chapter 3 Verse 8-14 [8] The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, "In you all the nations will be blessed." [9] So then, those who are of faith are blessed with the faithful Abraham. [10] For as many as are of the works of the law are under a curse. For it is written, "Cursed is everyone who doesn't continue in all things that are written in the book of the law, to do them." [11] Now that no man is justified by the law before God is evident, for, "The righteous will live by faith." [12] The law is not of faith, but, "The man who does them will live by them." [13] Christ redeemed us from the curse of the law, having become a curse for us. For it is written, "Cursed is everyone who hangs on a tree," [14] that the blessing of Abraham might come on the Gentiles through Christ Jesus; that we might receive the promise of the Spirit through faith.
