That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel: That the Gentiles should be fellow heirs - This is the substance of that mystery which had been hidden from all ages, and which was now made known to the New Testament apostles and prophets, and more particularly to St. Paul.
His promise in Christ - That the promise made to Abraham extended to the Gentiles, the apostle has largely proved in his Epistle to the Romans; and that it was to be fulfilled to them by and through Christ, he proves there also; and particularly in his Epistle to the Galatians, see Galatians 3:14. And that these blessings were to be announced in the preaching of the Gospel, and received on believing it, he every where declares, but more especially in this epistle.
