The eyes of your understanding being enlightened
By the Spirit of God already, to see the exceeding sinfulness of sin; the insufficiency of their own righteousness; the beauty, glory, fulness, and suitableness of Christ, as a Saviour; the excellency, truth, and usefulness of the doctrines of the Gospel; in which their understandings were before dark, but now had light into them: wherefore these words are not to be considered as part of the apostle's petitions, but rather as what was taken for granted by him; and are to be put into a parenthesis, and the following words to be joined in connection with the preceding verse; unless it should be thought, that the apostle prays for greater illuminations, and for more spiritual light, and that the eyes of their understandings might be more and more enlightened; the phrase, (lkvh Nye) , (omma thv dianoiav) , "the eye of the understanding", is Rabbinical, and often to be met with in Jewish writings F6; the Alexandrian copy, and several others, the Complutensian edition, the Vulgate Latin, and all the Oriental versions, read, "the eyes of your heart"; and to, (twbblh ynye) , "the eyes of the hearts, or minds", is a phrase used by the Jewish writers F7:
that ye may know what is the hope of his calling;
by which is meant, the effectual calling of the saints; which is not a call to an office, or a call merely by the external ministry of the word; but which is internal, special, powerful, high, and heavenly: and this is the calling of God, of which he is the author; who calls with an holy calling, unto eternal glory by Christ Jesus; and which is without repentance: and the hope of this calling, is either eternal happiness, which is the thing hoped for; or Christ, who is the ground and foundation of it; or the grace of hope, which is exercised on both; or all three: for hope of eternal glory, as it is founded on Christ, may be said to be the hope of the calling of God, because it is wrought in the soul at the time of the effectual calling, and what saints are then called to the exercise of; and calling grace, is an encouragement to hope for eternal life; since whom God calls, he justifies and glorifies: and now the apostle prays, that these saints who were called by the grace of God, might know more of Christ, the foundation of their hope; and what that is they are hoping for, and more and more what it is to hope for the same, upon the view of Christ's person, blood, and righteousness:
and what the riches of the glory of his inheritance in the saints;
the saints themselves are the Lord's portion, and the lot of his inheritance, in whom he is, and will be abundantly glorified; but here it rather seems to design the heavenly inheritance before spoken of, of which the Spirit is the earnest; and this is the Lord's, it is of his preparing, and it is his gift, and a very rich and glorious inheritance it is: hence it is not only signified by mansions, and everlasting habitations, by an house, and by a city, but by a kingdom; the riches of grace are preparatory to it, and the riches of glory are comprised in it; and this is in, or among the saints, who only have a right unto it, and a meetness for it; and what this inheritance is, with the riches and glory of it, will not be fully known in this life; and indeed but little of it is known; so that such a petition as this is always proper and pertinent.
