(18) The eyes of your understanding.--The true reading is of your heart, for which the words "of your understanding" have been substituted, so as to yield a simpler and easier expression. The heart is similarly spoken of in relation to spiritual perception in Romans 1:21; 1Corinthians 2:9; 1Corinthians 4:5; it signifies the inner man in his entirety; and the phrase here used seems to convey the all-important truth, that for the knowledge of God all the faculties of understanding, conscience, and affection must be called into energy by the gift of the light of God.

That ye may know.--The knowledge which St. Paul here desires for the Ephesians, in accordance with the whole tone of this Epistle, is a knowledge of heavenly things, only experienced in part upon earth--with an experience, however, sufficient to be an earnest of the hereafter. The succession of ideas follows the order of conversion--first, "calling;" then acceptance to "inheritance;" lastly, "inward working of divine power" in the accepted. To each the conception of looking onward is attached; to the "calling" "hope," to the "inheritance" "glory," to the "power" the exaltation of Christ (and of us with Him; see Ephesians 2:6) to the right hand of God.

The hope of his calling.--(See Ephesians 4:4.) That is, probably, "the thing hoped for," because promised, at our calling (as in Galatians 5:5; Colossians 1:5; Titus 2:3; Hebrews 6:18; and perhaps 1Timothy 1:1), for the other objects of knowledge with which it is here joined are certainly objective or external to ourselves. This hope is of the perfection of all, which we are called to enjoy really, but imperfectly, here.

The riches of the glory of his inheritance in the saints.--Comp. Colossians 1:27, "the riches of the glory of this mystery . . . which is Christ in you, the hope of glory." The inheritance of God is the unity with Christ, in which lies the earnest and hope of glory. "Among the saints" is best connected with the word "inheritance," showing that our personal inheritance of Christ gives us a place in the kingdom of heaven here and hereafter.

Verse 18. - That having the eyes of your heart enlightened. "The eyes of your heart" is an unusual expression, but it denotes that to see things clearly there is needed, not merely lumen siccum, but lumen madidum (to borrow terms of Lord Bacon), not merely intellectual clearness, but moral susceptibility and warmth - a movement of the heart as well as the head (compare the opposite state, "blindness of the heart," Ephesians 4:18). Ye may know what is the hope of his calling; the hope which he calls you to cherish. The glory which he invites you to look forward to, when Christ shall come again, how sure it is and how excellent! How infinitely it surpasses all earthly glory! How it at once ravishes and satisfies the heart! And what the riches of the glory of his inheritance in the saints. If the saints form God's heritage (see ver. 11), it may be asked Where are the riches of God's glory in them? But it is not necessary to take the ἐν τοῖς ἁγίοις so literally. It may be rendered, "in reference to the saints." The riches of the glory of his inheritance in reference to the saints is the riches of the glory of their privileges as the Lord's heritage, or people; that is, their privileges are glorious. But this glory is not limp, limited - it is wonderfully rich, full, abundant. God gives liberally - gives as a King, gives glory to all Christ's people. "When Christ, who is our life, shall appear, then shall ye also appear with him in glory" (Colossians 3:4); "The glory which thou gavest me I have given them." The difference between this glory and ether glory is, human glory is often unjustly accorded, it passes away with wonderful quickness; but this glory is real and everlasting. "When the chief Shepherd shall appear, ye shall receive a crown of glory that fadeth not away."

1:15-23 God has laid up spiritual blessings for us in his Son the Lord Jesus; but requires us to draw them out and fetch them in by prayer. Even the best Christians need to be prayed for: and while we hear of the welfare of Christian friends, we should pray for them. Even true believers greatly want heavenly wisdom. Are not the best of us unwilling to come under God's yoke, though there is no other way to find rest for the soul? Do we not for a little pleasure often part with our peace? And if we dispute less, and prayed more with and for each other, we should daily see more and more what is the hope of our calling, and the riches of the Divine glory in this inheritance. It is desirable to feel the mighty power of Divine grace, beginning and carrying on the work of faith in our souls. But it is difficult to bring a soul to believe fully in Christ, and to venture its all, and the hope of eternal life, upon his righteousness. Nothing less than Almighty power will work this in us. Here is signified that it is Christ the Saviour, who supplies all the necessities of those who trust in him, and gives them all blessings in the richest abundance. And by being partakers of Christ himself, we come to be filled with the fulness of grace and glory in him. How then do those forget themselves who seek for righteousness out of him! This teaches us to come to Christ. And did we know what we are called to, and what we might find in him, surely we should come and be suitors to him. When feeling our weakness and the power of our enemies, we most perceive the greatness of that mighty power which effects the conversion of the believer, and is engaged to perfect his salvation. Surely this will constrain us by love to live to our Redeemer's glory.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, , , "the eye of the understanding", is Rabbinical, and often to be met with in Jewish writings (f); 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, , "the eyes of the hearts, or minds", is a phrase used by the Jewish writers (g):

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.
