Gálatas 3

6 Even as Abraham believed God, and it was accounted to him for righteousness.

7 Know ye therefore, that they who are of faith, the same are the children of Abraham.

8 And the scripture foreseeing that God would justify the heathen through faith, preached before the gospel to Abraham, saying, In thee shall all nations be blessed.

9 So then they who are of faith are blessed with faithful Abraham.
