To whom God would make known,.... The spring and cause of the manifestation of the Gospel to the saints, and chosen of God, is not their works, for God does not call them with an holy calling according to them, but according to his own grace; nor any preparations and dispositions in them before such manifestation, towards the Gospel and the truths of it, for there are none such naturally in men, but all the reverse; nor a foresight of their better improvement of it, when made known, for this is not the method of divine grace, witness the instances of Sodom and Gomorrha, Tyre and Sidon; nor any holiness in them, or because they were sanctified, for they became so by the power of divine grace, through the Gospel revelation; but it is the pure sovereign good will and pleasure of God; see Eph 1:9; as appears from what they were before the Gospel came unto them, what is made known to them in it and by it; and from this, that they and not others, equally as deserving, are favoured with it:what [is] the riches of the glory of this mystery among the Gentiles.
The apostle, besides calling the Gospel a "mystery", as before, ascribes "glory" to it; it is a glorious mystery, there is a glory in all the mysteries of it; it is a glorious Gospel, as it is often called, in its author, subject, matter, use, and efficacy: and also "riches" of glory, or glorious riches; containing rich truths, an immense treasure of them, comparable to gold, silver, and precious stones; rich blessings of justification, pardon, reconciliation, adoption, and eternal life; and rich promises, relating both to this life, and that which is to come; all which were opened and made known, not to the Jews only, but "among the Gentiles" also; who before were aliens, enemies, exceeding wicked, poor, blind, and miserable, but now, through the Gospel, were become rich and glorious, wise, knowing, and happy:which is Christ in you, the hope of glory; this is to be connected with all that goes before: Christ is the riches of the Gospel; the riches of the divine perfections, which the Gospel more clearly displays than the works of creation or providence, are all in Christ, the fulness of them dwells in him; and this is the grace the Gospel reveals, that he, who was rich with all these, became poor to make us rich; the rich promises of the Gospel were all made to Christ, and are all yea and "Amen" in him; the rich blessings of it are all in his hands, righteousness, peace, and pardon, the riches both of grace and glory; the rich treasures of its divine truths are hid in him; and he is the substance of everyone of them: Christ is also the glory of the Gospel, inasmuch as he is the author, preacher, and subject of it; it is full of the glory of his person, both as the only begotten of the Father, and as the only Mediator between God and man; it is the glass through which this is seen: moreover, the glory of God in him is expressed hereby; the glory of his wisdom and power, of his truth and faithfulness, of his justice and holiness, of his love, grace, and mercy, and every other perfection, is eminently held forth in the Gospel; as this is great in the salvation and redemption of his people by Christ, which the Gospel brings the good news of; add to this, that that glory which the saints shall have with Christ, and will lie in the enjoyment of him to all eternity, is brought to light in the Gospel: Christ is also the mystery of the Gospel; he is one of the persons in the mystery of the Trinity; the mystery of his divine sonship, of his divine person, being God and yet man, man and yet God, and both in one person, and of his incarnation and redemption, makes a considerable part of the Gospel: and Christ, who is the sum and substance of it, is "in" his people; not only as the omnipresent God, as the author of the light of nature, as the Creator of all things, in whom all live, move, and have their beings, but in a way of special grace; and the phrase is expressive of a revelation of him in them, of their possession of him, of his inhabitation in them by his Spirit and grace, particularly by faith, and of their communion with him, in consequence of their union to him; and being so, he is the ground and foundation of their hopes of glory.
