(1) “Strengthened with power through His Spirit in the inward man” (ver. 16, R.V.). As wisdom was the burden of the former prayer (ch. i. 17), so strength is the main thought here. The order, too, is significant; wisdom and power, since power without knowledge would be highly dangerous. This strength comes from the Holy Spirit; He is the Agent of God’s enabling grace. And the strength is to extend “into the inward man.” The contrast seems to be between the inward and the outward, as in 2 Cor. iv. 16; Rom. vii. 22. The strength is not of the body, or of the mind, but of the soul. The “inward” is not exactly identical with the “new” man, but emphasises the inner essential life of the spirit as contrasted with the outer life of the body. “The hidden man of the heart.”
(2) “That Christ may dwell in your hearts through faith” (ver. 17, R.V.). This is the outcome of the inward strength of the Spirit, and almost every word needs attention. The indwelling of Christ is virtually identical with that of the Spirit (ch. ii. 22), although of course Christ and the Holy Spirit are never absolutely identified in Holy Scripture (2 Cor. iii. 17, 18). It is only in regard to the practical outcome in the believer’s experience that the indwelling of Christ and the Spirit amount to the same thing. This is to be a permanent indwelling and not a mere passing stay, just as believers together are described as a temple for God’s permanent habitation (ch. ii. 22, Greek). This permanent indwelling of Christ is to be “in your hearts.” Almost every prayer is thus concerned with the “heart,” the centre of the moral being, and the Apostle prays that Christ may make His home therein. This is no mere influence, but a Personal Presence, the Living Christ within, and it is to be “through faith.” It is faith that admits Christ to the heart, allowing Him to enter into every part of the “inward man.” And the same faith that admits Him permits Him to remain, reside, and rule. Faith, in a word, is the total response of the soul to the Lordship of Christ.
(3) “That ye, being rooted and grounded in love” (ver. 17). Here again the original expressions imply permanent results, and the two words “rooted” and “grounded” are beautifully complementary. The one refers to a tree, the other to a house, and the expressions point to those hidden processes of the soul which are the result of Christ’s indwelling and the Holy Spirit’s working. The power of the Spirit and the indwelling of Christ tend to our permanent inward establishment in the element and atmosphere of Christian love. This is one of the seven occasions in this short Epistle where we find the Pauline phrase, “in love,” referring to the sphere and atmosphere of our fellowship with God. The love no doubt means primarily and perhaps almost exclusively God’s love to us, as that in which we are to “live, and move, and have our being.”
(4) “May be strong to apprehend with all the saints what is the breadth and length and height and depth” (ver. 18, R.V.). Here again the emphasis is on strength, and the Apostle prays that we may have full strength to grasp, may be quite able to accomplish this purpose. Spiritual ideas can never be appropriated by intellectual action alone. It is not by brilliant intellect but by spiritual insight that we become “able to comprehend.” Although there is now no specific reference to love, it would seem as though the idea of verse 19 is already in view, and, assuming this to be the case, we have four aspects of the Divine love which we are to be strong to grasp. Its “breadth” means that there is no barrier to it, reminding us of the extent of the Divine counsels; its “length” tells us of the Divine foreknowledge and His thought of us through the ages; its “height” points to our Lord in heaven as the goal for the penitent believer; its “depth” declares the possibility of love descending to the lost abyss of human misery for the purpose of redemption. And the ability to grasp the Divine love in this fourfold way is to be experienced with “all the saints.” It is impossible to accomplish it alone; no spiritual exclusiveness is thinkable in this connection, to say nothing of the lower forms of egotism and selfishness. Twice in this brief writing does the Apostle refer to “all the saints” (ch. vi. 18), thereby reminding us of the place and power of each saint in the spiritual economy of God. One saint will be able to comprehend a little, another saint a little more, and so on, until at length all the saints together are “strong to grasp” the Divine love. The wider our fellowship the fuller and firmer our hold of the love of Christ. This is doubtless why public worship is so strongly emphasised in the New Testament. “Where two or three are gathered together in My Name, there am I.” The experiences of our fellow-worshippers are always intended to be, and usually will be, of help to our own fuller realisation of our Lord and Master. The soul is justified solitarily and alone, but it is sanctified only in the community of believers.
(5) “And to know the love of Christ which passeth knowledge” (ver. 19). If we are correct in interpreting verse 18 of the Divine love, the present verse will be the climax of this part of the prayer, and it has been helpfully suggested that we have here the “fifth dimension” of the love of Christ after the four already mentioned. Not only are they to experience breadth and length and height and depth but also the inwardness; they are to know by personal experience the love of Christ as it can only be known by those who have fellowship with Him. It is a love that surpasses knowledge, just as His power surpasses everything (ch. i. 19). The paradox of knowing that which surpasses knowledge will not be misunderstood from the standpoint of spiritual experience, because it is the difference between apprehending and comprehending. We know, and know deeply, increasingly, blessedly, and yet all the while there are infinite stretches of love beyond our highest experiences.
(6) “That ye may be filled unto all the fulness of God” (ver. 19, R.V.). This is the climax of the prayer and is the culminating purpose of the work of the Spirit and the indwelling of Christ. Strength, indwelling, love, and knowledge are to issue in fulness, and we are to be “filled unto all the fulness of God.” In the former prayer this fulness is associated with Christ and with His body the Church (ch. i. 23), but here it is specifically associated with God and ourselves as believers in Christ. When these two passages are associated with ch. v. 18, which speaks of the fulness of the Spirit, we have the word “fulness” connected with each Person of the Blessed Trinity. What it means for the soul to be filled to overflowing with the presence of God itself is beyond our comprehension; it can only be a matter of personal experience as we seek to fulfil the proper conditions. Such a prayer for the fulness of God is best expressed in Miss Havergal’s words—
“Lord, we ask it, scarcely knowing
What this wondrous gift may be;
But fulfil to overflowing,
Thy great meaning let us see.”
