Then notice that there is also here another condition for this deep and blessed knowledge laid down in these words, 'That ye may be able to comprehend with all saints.' That is to say, our knowledge of the love of Jesus Christ depends largely on our sanctity. If we are pure we shall know. If we were wholly devoted to Him we should wholly know His love to us, and in the measure in which we are pure and holy we shall know it. This heart of ours is like a reflecting telescope, the least breath upon the mirror of which will cause all the starry sublimities that it should shadow forth to fade and become dim. The slightest moisture in the atmosphere, though it be quite imperceptible where we stand, will be dense enough to shut out the fair, shining, snowy summits that girdle the horizon and to leave nothing visible but the lowliness and commonplaceness of the prosaic plain.
If you want to know the love of Christ, first of all, that love must purify your souls. But then you must keep your souls pure, assured of this, that only the single eye is full of light, and that they who are not 'saints' grope in the dark even at midday, and whilst drenched by the sunshine of His love, are unconscious of it altogether. And so we get that miserable and mysterious tragedy of men and women walking through life, as many of you are doing, in the very blaze and focus of Christ's love, and never beholding it nor knowing anything about it.
Observe again the beginning of this path of knowledge, which we have thus traced. There must be, says my text, an indwelling Christ, and so an experience, deep and stable, of His love, and then we shall know the love which we thus experience. But how comes that indwelling? That is the question for us. The knowledge of His love is blessedness, is peace, is love, is everything; as we shall see in considering the last stage of this prayer. That knowledge arises from our fellowship with and our possession of the love of God, which is in Jesus Christ. How does that fellowship with, and possession of the love of God in Jesus Christ, come? That is the all-important question. What is the beginning of everything? 'That Christ may dwell in your hearts by faith.' There is the gate through which you and I may come, and by which we must come if we are to come at all into the possession and perception of Christ's great love. Here is the path of knowledge. First of all, there must be the simple historical knowledge of the facts of Christ's life and death for us, with the Scripture teaching of their meaning and power. And then we must turn these truths from mere notions into life. It is not enough to know the love that God has to us, in that lower sense of the word 'knowledge.' Many of you know that, who never got any blessing out of it all your days, and never will, unless you change. Besides the 'knowing' there must be the 'believing' of the love. You must translate the notion into a living fact in your experience. You must pass from the simple work of understanding the Gospel to the higher act of faith. You must not be contented with knowing, you must trust. And if you have done that all the rest will follow, and the little, narrow, low doorway of humble self-distrusting faith, through which a man creeps on his knees, leaving outside all his sin and his burden, opens out into the temple palace—the large place in which Christ's love is imparted to the soul.
Brethren, this doctrine of my text ought to be for every one of us a joy and a gospel. There is no royal road into the sweetness and the depth of Christ's love, for the wise or the prudent. The understanding is no more the organ for apprehending the love of Christ than the ear is the organ for perceiving light, or the heart the organ for learning mathematics. Blessed be God! the highest gifts are not bestowed upon the clever people, on the men of genius and the gifted ones, the cultivated and the refined, but they are open for all men; and when we say that love is the parent of knowledge, and that the condition of knowing the depths of Christ's heart is simple love which is the child of faith, we are only saying in other words what the Master embodied in His thanksgiving prayer, 'I thank Thee, Father! Lord of heaven and earth, because Thou hast hid these things from the wise and prudent, and hast revealed them unto babes.'
And that is so, not because Christianity, being a foolish system, can only address itself to fools; not because Christianity, contradicting wisdom, cannot expect to be received by the wise and the cultured, but because a man's brains have as little to do with his trustful acceptance of the Gospel of Jesus Christ as a man's eyes have to do with his capacity of hearing a voice. Therefore, seeing that the wise and prudent, and the cultured, and the clever, and the men of genius are always the minority of the race, let us vulgar folk that are neither wise, nor clever, nor cultured, nor geniuses, be thankful that all that has nothing to do with our power of knowing and possessing the best wisdom and the highest treasures, but that upon this path the wayfaring man though a fool shall not err, and all narrow foreheads and limited understandings, and poor, simple uneducated people as well as philosophers and geniuses have to learn love by their hearts and not by their heads, and by a sense of need and a humble trust and a daily experience have to appropriate and suck out the blessing that lies in the love of Jesus Christ. Blessed be His name! The end of all aristocracies of culture and superciliousness of intellect lies in that great truth that we possess the deepest knowledge and highest wisdom when we love and by our love.
II. Now a word in the next place as to the other thought here, that not even the loving heart can know the love of Christ.
'It passeth knowledge,' says my text. Now I do not suppose that the paradox here of knowing the love of Christ which 'passeth knowledge' is to be explained by taking 'know' and 'knowledge' in the two different senses which I have already referred to, so as that we may experience, and know by conscious experience, that love which the mere understanding is incapable of grasping. That of course is an explanation which might be defended, but I take it that it is much truer to the Apostle's meaning to suppose that he uses the words 'know' and 'knowledge' both times in the same sense. And so we get familiar thoughts which I touch upon very briefly.
Our knowledge of Christ's love, though real, is incomplete, and must always be so. You and I believe, I hope, that Christ's love is not a man's love, or at least that it is more than a man's love. We believe that it is the flowing out to us of the love of God, that all the fulness of the divine heart pours itself through that narrow channel of the human nature of our Lord, and therefore that the flow is endless and the Fountain infinite.
I suppose I do not need to show you that it is possible for people to have, and that in fact we do possess a real, a valid, a reliable knowledge of that which is infinite; although we possess, as a matter of course, no adequate and complete knowledge of it. But I only remind you that we have before us in Christ's love something which, though the understanding is not by itself able to grasp it, yet the understanding led by the heart can lay hold of, and can find in it infinite treasures. We can lay our poor hands on His love as a child might lay its tiny palm upon the base of some great cliff, and hold that love in a real grasp of a real knowledge and certitude, but we cannot put our hands round it and feel that we comprehend as well as apprehend. Let us be thankful that we cannot.
His love can only become to us a subject of knowledge as it reveals itself in its manifestations. Yet after even these manifestations it remains unuttered and unutterable even by the Cross and grave, even by the glory and the throne. 'It is as high as heaven; what canst thou do? deeper than hell; what canst thou know? The measure thereof is longer than the earth, and broader than the sea.'
