Colossians 1:26

[Even] the mystery which hath been hid from ages and generations,.... This is said, as explanative of the word of God; signifying that he did not mean the Scriptures in general, which are the word of God, and every part of them; some part of which is historical, another prophetical, another practical, and another doctrinal; nor the law, which also is the word of God, but the Gospel, called "the mystery", as it often is; because it contains things, which, though revealed, are mysteries to a natural man; and even to enlightened persons, who have the clearest view of them, the "modus" of them is not to be accounted for; such as the doctrines of the Trinity, of the union of the two natures in Christ, the incarnation of the Son of God, the union and communion of the church with Christ, the resurrection of the dead, c. And though perhaps great and special regard may be here had to the calling of the Gentiles, which, though revealed in the prophecies of the Old Testament, was in a great measure hid in them, and not so clearly known in ages and generations past as now, yet the whole may be applied to the Gospel mystery in general which was first hid in the heart of God, in his thoughts and purposes, in his counsel and covenant, and in his Son, in whom are hid all the treasures of wisdom and knowledge; and then in the ceremonies and shadows of the law, which but few had any insight into, and discerning of; and, during that dispensation, was wholly hid from the Gentiles; and but in part known by the Jews, and but by a few, and comparatively by them very darkly; and not so clearly by the angels themselves, who pry into these mysteries, and now, under the Gospel dispensation, learn from the church the manifold wisdom of God; and indeed it was hidden from all men, Jews and Gentiles, in a state of nature, and even from the wise and prudent of this world:

but now is made manifest to his saints; now under the Gospel dispensation, since the coming of Christ; there is an external revelation of the Gospel by him, more clearly, by whom grace and truth came, called the revelation of Christ; and an internal revelation of it by his Spirit, who is the spirit of wisdom and revelation, in the knowledge of him; which is made to saints, the holy apostles and prophets, who are the saints to whom this faith, and the mystery of it, were first delivered with so much power and evidence; and to all the elect of God, whom he has separated for himself in eternal election; whom Christ has sanctified by his blood, and to whom he is made sanctification; and who are called with an holy calling, have principles of grace and holiness wrought in them by the Spirit of God, and therefore called "his" saints; these have only a spiritual discerning of the Gospel, for the natural man neither knows nor receives it.
