Heavenly Geometry
Ephesians 3:18
May be able to comprehend with all saints what is the breadth, and length, and depth, and height;


This Divine mensuration is an art of the most desirable kind, as appears from its being the object of most earnest apostolic prayers.

I. Like a wise and enlightened teacher, Paul desires for the saints that they should receive THAT PREVIOUS EDUCATION WHICH IS NECESSARY BEFORE THEY WILL BE ABLE TO ENTER UPON SUCH A SCIENCE AS THE MEASUREMENT OF CHRIST'S LOVE. When lads go to school they are not at first put to study algebra, nor are they sent out to make a trigonometrical survey of a county. The schoolmaster knows that they must have a rudimentary knowledge of arithmetic, or else to teach them algebra would be waste of time, and that they must have some acquaintance with common geometry, or it would be absurd to instruct them in surveying. He therefore begins with the elementary information, and when they have learned simpler matters they are ready for the more difficult studies. They climb the steps of the door of science, and then they are introduced to her temple. The Apostle Paul does not propose that the new convert should at once be able to measure the breadth and length and depth and height of the love of Christ; he knows that this is not within the range of his infant mind; for the newborn spirit has a time of growth to go through before it can enter into the deep things of God. If you will kindly refer to the text you will see what this previous education is which the apostle desired for the saints. It is very fully described in three parts.

1. He desired that their spiritual faculties might be strengthened, for he prays that they might be "strengthened with might by the Spirit in the inner man." The schoolmaster knows that the boy's mind must be strengthened, that his understanding must be exercised, his discernment must be developed, and his memory must be rendered capacious before he may enter upon superior studies; and the apostle knows that our spiritual faculties must undergo the same kind of development; that our faith, for instance, must be unwavering, that our love must become fervent, that our hope must be bright, that our joy must be increased, and then, but not till then, we shall be able to comprehend the length and breadth of love Divine. We are to be strengthened in the inner man by the Spirit of God; and who can strengthen as He strengthens?

2. He desired that the object of study may be evermore before them: "that Christ may dwell," etc. A good tutor not only wishes his scholar may have a disciplined mind able to grapple with the subject, but he endeavours to keep the subject always before him; for in order to attain to any proficiency in a science the mind must be abstracted from all other thoughts, and continually exercised with the chosen theme. You will never find a man preeminent in astronomy unless astronomy has become the lord of mind, and holds a sway over his mind even in his dreams. The anatomist must be bound to nerves, and bones, and blood vessels, as the galley slave is bound to the oar, or he will never master his subject, The botanist must be enamoured of every flower, and wedded to every plant, or the fields will utterly bake him. "Through desire a man, having separated himself, seeketh and intermeddleth with all wisdom." Solomon knew what he wrote when he said, "Separated himself," for without separation or abstraction there can be no progress. Now, the apostle desires that we who are believers, our faculties being strengthened, may have the person of Jesus constantly before us to inflame our love, and so increase our knowledge. See how near he would have Jesus to be! "That Christ may dwell in your hearts by faith." You cannot get a subject closer to you than to have it on the inner side of the eyes; that is to say, in the heart itself. The astronomer cannot always see the stars because they are far away, and outside of him; but our star shines in the heaven of our hearts evermore. The botanist must find his flowers in their seasons, but our plant of renown blooms in our souls all the year round. We carry the instruments of our saintly art, and the object of our devout contemplation within ourselves. As a scholar carries in his pocket a small edition of his favourite classic, so do we carry Christ in our hearts; what if I say we bear about with us a heart edition of the Liber Crucis, the Book of the Cross. If we knew more fully by experience the meaning of "Christ in you the hope of glory," our heaven-taught affections, which are the best part of our inner man, might be continually exercised upon the person, the work, and the love of our dear Redeemer.

3. The apostle prays further that they may have practical exercise in the art of holy love; "that ye being rooted and grounded in love." Every experienced tutor knows that it is greatly helpful to the student to exercise him in his chosen pursuit upon some lower and inferior branch of it, so as to lead him gradually to the higher points of it. If, for instance, he means him to understand the surveying of estates, he bids him measure a field containing an acre or two. If he means him to map out a country, he sets him first to make a plan of a neighbouring field or a farm. The apostle acts upon the same method. "That ye, being rooted and grounded in love, may be able to comprehend the breadth and length of the love of Christ." Having the love of Jesus in you, possessed with love to Christ, you will be practised in the exercise of love, and so will understand the love which filled the Saviour. You will learn to do business upon the greater waters of the Redeemer's infinite love to His people, as you sail upon the stream of your love to Him. Two expressions are used: — "rooted," like a living tree which lays hold upon the soil, twists itself round the rocks, and cannot be upturned — "grounded," like a building which has been settled, as a whole, and will never show any cracks or flaws in the future through failures in the foundation. The apostle wishes us to be rooted and grounded in love, a vital union being established between our souls and Jesus, so that we love Him because He first loved us; and also a fiducial union, or a union of trust, by which we rest upon Jesus as the stones of a wall are settled upon the foundation.

II. We now come to consider more closely the SCIENCE OF HEAVENLY MENSURATION ITSELF. According to the text, we have a solid body to deal with, for we are to measure its breadth and length, and depth, and height. This cubical measurement — for it lieth foursquare, like the new Jerusalem — proves the reality of the body to be measured. Alas, to a great many religious people the love of Jesus is not a solid substantial thing at all — it is a beautiful fiction, a sentimental belief, a formal theory; but to Paul it was a real, substantial, measurable fact. No one knows the love of Christ at all if he does not know it to be real, and no one has felt it in his soul at all unless it becomes so real as to constrain him and move him into actual activity. The apostle desires that when the love of Christ becomes to us a solid reality we may have close communion with it. You may measure the breadth and length of a thing at a great distance, but you cannot very well measure its depth without drawing near to it. What a holy familiarity with Jesus do the words imply when we come to measurements of all kinds! What condescension is this which allows the sacred heart to be fathomed like a sea, and to be measured as a field! Shall the infinite thus bow itself to man? Shall man refuse to commune with such condescending love? Let me come to the very words of our text, and point out to you their order.

1. The first object of the Christian's knowledge should be the breadth of the Saviour's love. I know a certain school of Christians who have need to study this point, for they have a very narrow idea of the Lord's loving kindness. They conceive of Divine love as a very narrow stream, they have never seen it to be a mighty, flowing, abounding, and rejoicing river, such as it really is. The love of Jesus Christ does not surround our favoured island alone, but, like the ocean, it washes every shore. The love of Jesus Christ has been extended to kings upon their thrones, but with equal and more frequent bounty to the slaves in their dungeons.

2. The next object of study is the length of Christ's love. "I have loved thee with an everlasting love." Coeval then with Deity itself is the love of Deity towards its chosen ones. God did love us in His Son long before the world began. If an angel were to start from today with the design of finding out when God's love began he would doubtless fly on till he lingered at the Cross. "Here," he would say, "here is the fountain, here is the source of it all." But he would be reminded that "God so loved the world that He gave His only begotten Son." Then there was a love before the giving of His Son. He would fly onward till he paused at Isaiah's day and heard of God's love in the prophecy that the Son of man should bear the iniquity of His people. He would say, "Surely it begins here!" But saints would remind him of yet older words of comfort, and he would fly on till he stopped outside of the garden of Eden and heard the Lord say, "The Seed of the woman shall bruise the serpent's head." "Surely," saith he, "it began here." But, divinely instructed, he would go back yet further, even to the eternal councils where first of all salvation was planned and contrived in the cabinets of wisdom before the world was. He would have to go back, back, back, till creation had vanished, till there remained not a shred of existence except the absolute self-existent Deity, and then in the Eternal Mind he would see thoughts of love toward a people to be formed for himself. This knowledge of the length of love does not always come to Christians early in their history. This love is not only without beginning, but it is without pause. There is never a moment when Jesus ceases to love His people. The love of Jesus knows nothing of suspended animation. There are some rivers in Australia which lose themselves, and for miles along their bed you find nothing but dry stones at certain seasons of the year. It is never so with the love of Christ: it is tong, and without a break from beginning to end; it is a chain without a single broken or feeble link.

3. The depth of the love of Jesus! Consider it as stooping to look upon such an insignificant creature as man! View the depth of that love in receiving such sinful creatures into His embrace! O sinner! you cannot have gone too deep for Christ's love to reach you. O backslider! you cannot have sinned too foully for forgiveness.

4. Think next of the height of the Master's love. You see it is put last, as the highest point of learning, There are some who have advanced as far as to understand somewhat of the depths, who do not know the full dignity and glory of an heir of heaven, and have felt but little of the power of His ascension. Why, the love of Jesus, even in this present life, is a height unspeakable, for has it not lifted us up to become sons of God? Yet, brethren, the height of this love will be best seen in a future state. You shall be borne up to dwell with Christ in the clouds when the world is in a blaze, and when the judgment is passed you shall be carried by angels' wings up to the seventh heaven where God dwelleth. Oh the breadth, the length, the depth, the height! To sum up what we have said in four words. For breadth the love of Jesus is immensity, for length it is eternity, for depth it is immeasurability, and for height it is infinity.

(C. H. Spurgeon.)
