God had promised to adopt the children of Israel again, He must adopt the Gentiles also. Otherwise this resolution would rest upon mere caprice, which cannot be thought of in God” (Hengstenberg). Moreover, although membership in the nation of the Old Testament covenant rested primarily upon lineal descent, it was by no means exclusively confined to this; but, from the very first, Gentiles also were received into the citizenship of Israel and the congregation of Jehovah through the rite of circumcision, and could even participate in the covenant mercies, namely, in the passover as a covenant meal (Exo 12:14). There was in this an indirect practical prophecy of the eventual reception of the whole of the Gentile world into the kingdom of God, when it should attain through Christ to faith in the living God. Even through their adoption into the congregation of Jehovah by means of circumcision, believing Gentiles were exalted into children of Abraham, and received a share in the promises made to the fathers. And accordingly the innumerable multiplication of the children of Israel, predicted in Rom 9:10, is not to be restricted to the actual multiplication of the descendants of the Israelites now banished into exile; but the fulfilment of the promise must also include the incorporation of believing Gentiles into the congregation of the Lord (Isa 44:5). This incorporation commenced with the preaching of the gospel among the Gentiles by the apostles; it has continued through all the centuries in which the church has been spreading in the world; and it will receive its final accomplishment when the fulness of the Gentiles shall enter into the kingdom of God. And as the number of the children of Israel is thus continually increased, this multiplication will be complete when the descendants of the children of Israel, who are still hardened in their hearts, shall turn to Jesus Christ as their Messiah and Redeemer (Rom 11:25-26).
