41. For Christ to dwell in the heart is simply for the heart to know him; in other words, to understand who he is and what we are to expect from him—that he is our Saviour, through whom we may call God our Father and may receive the Spirit who imparts courage to brave all trials. It is thus that Christ dwells with us, in our hearts. Only so can he be embraced; for he is not an inanimate thing, but the living God. How does man lay hold of the Saviour in the heart? Not by embracing him intellectually. It is accomplished only by living faith. Christ will not permit himself to be received by works, nor to be apprehended with mental vision; he will consent only to be embraced by the heart. If your faith be true and on a firm foundation, you have and feel Christ in your heart and are aware of all he thinks and does in heaven and on earth—how he rules through his Word and his Spirit, and the attitude of those who have Christ and those who have him not.
42. Paul desires Christ to be efficacious in the hearts of his followers unto the full realization of the promises of the Word—liberation from sin and death, and assurance of grace and eternal life. It is impossible for the heart having such experience to be other than firm and courageous to oppose the terrors of the devil and the world. But the heart which has not yet arrived at this point is here advised what course to take, namely, to pray God for such faith and strength, and to avail himself of the prayers of others to the same end. So much in regard to faith; now follows the mention of love.
"That ye, being rooted and grounded in love."
LOVE, THE EXPRESSION OF FAITH.
43. This is an unusual way of speaking. Is it not in faith that we are to be rooted, engrafted and grounded? Why, then, does Paul here substitute "love?" I reply: Faith, it is true, is the essential thing, but love shows whether or no faith is real and the heart confident and courageous in God. Where one has an unquestioning confidence that God is his Father, necessarily, be his faith never so weak, that faith must find expression in word and deed. He will serve his neighbor in teaching and in extending to him a helping hand. This is what Paul calls being rooted and grounded in love—having the conscious experience of possessing true faith. Love is the test that determines the reality of faith. Peter says (2 Pet 1, 10), "Give the more diligence to make your calling and election sure." That is, proceed to good works that others may see and you experience that you have true faith. Until you do, you will always be uncertain, vacillating, superficial in heart, not rooted and grounded. So by these two clauses Paul teaches, first, that we should have in our hearts genuine faith toward God; and second, that faith should find expression in loving service to one's neighbor.
"May be strong to apprehend with all the saints what is the breadth and length and height and depth."
TRUE CHRISTIANS FIND CHRIST EVERYWHERE.
44. These words represent another feature of the apostle's desire for his Christians to be established and comforted in God through faith, and rooted and grounded in love toward their neighbors. "When you are thus strengthened," he would say, "and are perseveringly pressing forward, you will be able to grasp with all saints the four parts, to increase therein and to appreciate them more and more." Faith alone effects this apprehension. Love is not the moving force here, but it contributes by making faith manifest.
45. Some teachers would make these words reflect and measure the holy cross. But Paul does not say a word about the cross. He simply says, in effect: "That you may apprehend all things; may see the length and breadth, the height and depth, of Christ's kingdom." This condition obtains when my heart has reached the point where Christ cannot make the spiritual life too long or too wide for me to follow, nor high enough or deep enough to cause my fall from him or his Word; the point where I may be satisfied that wherever I go he is, and that he rules in all places, however long or broad, deep or high, the situation from either a temporal or eternal point of view. No matter how long or wide I measure, I find him everywhere. David says (Ps 139, 7-8): "Whither shall I go from thy Spirit? or whither shall I flee from thy presence? If I ascend up into heaven, thou art there: if I make my bed in Sheol, behold, thou art there." Christ rules eternally. His length and breadth, his depth and height, are unlimited. If I descend into hell, my heart and my faith tell me he is there.
46. The sum of the matter is this: Depressed or exalted, circumscribed in whatsoever way, dragged hither or thither, I still find Christ. For he holds in his hands everything in heaven or on earth, and all are subject to him—angels, the devil, the world, sin, death and hell. Therefore, so long as he dwells in my heart, I have courage, wherever I go, I cannot be lost. I dwell where Christ my Lord dwells. This, however, is a situation impossible to reason. Should reason ascend a yard above the earth or descend a yard below, or be deprived of the tangible things of the present, it would have to despair. We Christians are, through Christ, better fortified. We are assured that he dwells everywhere, be it in honor or dishonor, hunger, sorrow, illness, imprisonment, death or life, blessing or affliction. It is Paul's desire for the Ephesians that God give them grace and strength to have such heart-apprehension of his kingdom. He concludes the details of his prayer in these words:
