Gal 3:7 Know ye therefore that they which are of faith, the same are the children of Abraham.
Gal 3:8 And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.
Gal 3:9 So then they which be of faith are blessed with faithful Abraham.

Gal 3:11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
Gal 3:12 And the law is not of faith: but, The man that doeth them shall live in them.
Gal 3:13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:
Gal 3:14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
