May be made strong to comprehend with all the saints. The subject to be comprehended is not only beyond man's natural capacity, but beyond the ordinary force of his spiritual capacity. The tiring to be grasped needs a special strength of heart and soul; the heart needs to be enlarged, the mental "hands of the arms" need to be made strong (Genesis 49:24).
But the attainment is not impossible—it is the experience of "all the saints;" all God's children are enabled to grasp something of this. What is the breadth, and length, and depth, and height. No genitive being given, it has been a difficult point to settle to what these dimensions must be held to be applicable.
Some think that the love of Christ in the following clause must be meant; but surely when that is made the subject of a separate part of the prayer, and is not in the genitive but the objective case, governed by a verb of its own, this explanation is not to be enter-rained.
Others, with more reason, think that the idea of a temple was in the mind of the writer, as it certainly was in Ephesians 2:21, Ephesians 2:22, and that it is the dimensions of the temple he had here in his eye, the prayer being that the Ephesians might comprehend the vastness and glory of that spiritual temple which is constituted by all believers, and in which God dwells by the Spirit.
Even this, however, would not divest the construction of abruptness, and it would fit in but poorly with the context, in which the tenor o f the apostle's prayer is that a profusion of Divine blessing might be enjoyed by the Ephesians.
If a genitive must be supplied, may we not conceive the apostle to have had in his view the entire provision God has made in Christ for the good of his people, so that the dimensions would be those of the gospel storehouse, the vast reservoir out of which the Church is filled?
"Breadth" might denote the manifoldness of that provision; "length," its eternal duration; its "depth" might be represented by the profundity of Christ's humiliation; and its "height" by the loftiness of the condition to which his people are to be raised.
To comprehend this, to understand its existence and its richness, is to get our faith enlarged, our expectations expanded; it is through this comprehension that "all the saints" have got their wants supplied, and their souls filled as with marrow and fatness.
