The Scriptures ascribe no righteousness to Abraham except through faith. The Scriptures speak of Abraham as he stands before God, a man justified by faith. Because of his faith God extends to him the promise: "In thee shall all nations be blessed."
VERSE 9. So then they which be of faith are blessed with faithful Abraham.
The emphasis lies on the words "with faithful Abraham." Paul distinguishes between Abraham and Abraham. There is a working and there is a believing Abraham. With the working Abraham we have nothing to do. Let the Jews glory in the generating Abraham; we glory in the believing Abraham of whom the Scriptures say that he received the blessing of righteousness by faith, not only for himself but for all who believe as he did. The world was promised to Abraham because he believed. The whole world is blessed if it believes as Abraham believed.
The blessing is the promise of the Gospel. That all nations are to be blessed means that all nations are to hear the Gospel. All nations are to be declared righteous before God through faith in Christ Jesus. To bless simply means to spread abroad the knowledge of Christ's salvation. This is the office of the New Testament Church which distributes the promised blessing by preaching the Gospel, by administering the sacraments, by comforting the broken-hearted, in short, by dispensing the benefits of Christ.
The Jews exhibited a working Abraham. The Pope exhibits a working Christ, or an exemplary Christ. The Pope quotes Christ's saying recorded in John 13:15, "I have given you an example, that ye should do as I have done to you." We do not deny that Christians ought to imitate the example of Christ; but mere imitation will not satisfy God. And bear in mind that Paul is not now discussing the example of Christ, but the salvation of Christ. That Abraham submitted to circumcision at the command of God, that he was endowed with excellent virtues, that he obeyed God in all things, was certainly admirable of him. To follow the example of Christ, to love one's neighbor, to do good to them that persecute you, to pray for one's enemies, patiently to bear the ingratitude of those who return evil for good, is certainly praiseworthy. But praiseworthy or not, such virtues do not acquit us before God. It takes more than that to make us righteous before God. We need Christ Himself, not His example, to save us. We need a redeeming, not an exemplary Christ, to save us. Paul is here speaking of the redeeming Christ and the believing Abraham, not of the model Christ or the sweating Abraham.
The believing Abraham is not to lie buried in the grave. He is to be dusted off and brought out before the world. He is to be praised to the sky for his faith. Heaven and earth ought to know about him and about his faith in Christ. The working Abraham ought to look pretty small next to the believing Abraham.
Paul's words contain the implication of contrast. When he quotes Scripture to the effect that all nations that share the faith of faithful Abraham are to be blessed, Paul means to imply the contrast that all nations are accursed without faith in Christ.
VERSE 10. For as many as are of the works of the law are under the curse.
The curse of God is like a flood that swallows everything that is not of faith. To avoid the curse we must hold on to the promise of the blessing in Christ.
The reader is reminded that all this has no bearing upon civil laws, customs, or political matters. Civil laws and ordinances have their place and purpose. Let every government enact the best possible laws. But civil righteousness will never deliver a person from the condemnation of God's Law.
