The time of this great enlargement of the church of God was the advent of the Saviour. The Christian church succeeded as heirs of all the promises, benefits, and free grace of the ancient church and people of God;—in fact, became heirs of Abraham;—“And the father of circumcision to them, who are not of the circumcision only, but who walk in the steps of that faith of our father Abraham, which he had being yet uncircumcised. For the promise that he should be the heir of the world was not to Abraham, or to his seed through the law, but through the righteousness of faith.” * * * “Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all, (as it is written, I have made thee the father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not, as though they were.” _Romans_ iv. 11, 12, 16, 17. “Therefore remember, that ye being in times past Gentiles in the flesh, who are called uncircumcision by that which is called the circumcision in the flesh made by hands; “That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenant of promise, having no hope, and without God in the world. “But now in Christ Jesus, ye who sometime were afar off, are made nigh by the blood of Christ; for he is our peace, who hath made both one; and hath broken down the middle wall of partition between us.” _Eph._ ii. 11, 12, 13, 14. “Know ye, therefore, that they which are of faith, the same are children of Abraham. And the scripture foreseeing that God would justify the heathen by faith, preached before the gospel to Abraham, saying, In thee shall all nations be blessed.” _Gal._ iii. 7, 8. And wherefore Peter very properly describes the Gentile church of Christ by similar language applied to the Jews, the chosen people of God to whom the promises of the law were made: “But ye are a chosen generation, a royal priesthood, a holy nation, a peculiar people; that ye should show forth the praises of him who hath called you out of darkness into his marvellous light; which in time past were not a people, but are now a people of God; which had not obtained mercy, but have now obtained mercy.” 1 _Peter_ ii. 9, 10. The theological student will recollect many more very pertinent proofs of the heirship of the Christian church to the chosen people of God. “Think not I am come to destroy the law, or the prophets; I come not to destroy the law, but to fulfil.” _Matt._ v. 17. So far then as the Gentile nations have become Christianized, have become the followers of Christ, so far they have, through faith, become the peculiar people of God, and heirs and children of Abraham; and, as heirs, succeeded to all things resulting from the providence and grace of God to his peculiar people.
