The Jasper Wall
Revelation 21:18
And the building of the wall of it was of jasper: and the city was pure gold, like to clear glass.


The picture of the measurement of the city has a colour and tone of triumph in it. Heaven rejoices in its divinely perfect proportions. Goal marks with the exactness of love the holy city that mirrors heaven's own beauty, and would proclaim its lineaments and proportions of glory to all the world. There are some things that are not worth measuring. Heaven will take no copy of some lives, that they may die the sooner. The measurement also symbolises heaven's inexorable demand for ideal perfection in human life. In the city of God there must be no defect or redundancy. The vessels of God's glory must be without flaw and without alloy. No column in His temple shall be broken or deficient. God will not stop half-way, or be content with rough approximations to His ideal. Hence it is that the best human structures must fail and be condemned. This measuring is, therefore, further, a symbol of eternal preservation. To "measure off" implies a selection for some purpose or other, and here it is clearly for the purpose of honour and preservation. In the first verse of the eleventh chapter we find "the temple of God and the altar, and them that worship therein," measured in the same way, while "the court without the temple" is left unmeasured. In that passage the symbol is explained by the assertion that the" outer court" is so far left unprotected that it has been given unto the nations for forty and two months.

I. The first question that presses for an answer in any attempt to interpret this symbol is, What relation does the jasper wall hold to the general structure and constitution of that city?

1. In the first place, the "jasper wall" gives unity to the varied expanse of the city. In the ancient conception, a city without a surrounding wall scarcely found a place in the mind at all, except as a picture of desolation and ruin. The myriad-sided life of the city and State can never be gathered into perfect harmony except within the wall of jasper, except by being pervaded by the Divine life in its profoundest manifestation of love. Men will of a certainty remain scattered, in spite of all human devices, until they are united by that transcendent love which comes through faith in Jesus Christ. Through this, and through this alone, are those strong conflicting interests overcome that separate men from one another.

2. Further, this wall of jasper marks the extent of the city. With the encompassing wall the city ends. The description which John gives, therefore, represents the ideal city as being of vast and magnificent extent. It is bounded by the "jasper wall" — that is, by nothing of narrower dimensions than the vast thought, purpose, and power of redeeming love. At this point John adds symbol to symbol, in order that there may be no mistake as to his meaning, and that the meaning may be emphasised in the strongest way. The length and breadth and height of the city are given in symbolic numbers. The three are equal, and their measurement is twelve thousand furlongs. That is, we are informed by a new symbol that this city is as vast as the energies of the Divine kingdom of redeeming love. Of course, it is now clear that the length and the breadth and the height of it cannot be other than equal. In every direction of its life it must reach the full measurement of redeeming power. As far as the love of Calvary can transform the lives of men, as far as it can lift the thoughts and purposes and attainments of men towards the lofty heavens, so great is the length, the breadth, and the height of the holy city.

3. It is instructive to note, further, that the wall of a city was its great watch-tower. Upon its summit the watchman stood to take observation of the country around, to warn the city of danger, and to instruct it concerning the outer world. The walls of the ideal city are not only ramparts, but also watch-towers, the place of furthest vision. The blind children of this world make the mistake of supposing that the city of redemption is a narrow enclosure, which hides from us the wide and varied prospect which they imagine lies before themselves. They pity us, and invite us to leave the narrowness of the Cross, and the fetters of redeeming love, that our vision may become as free as theirs. It is they that are enclosed around, and cannot see afar off. The Cross is the true watch-tower of the mind, as well as of the spirit. It is not only the centre of power, but also of wisdom and knowledge. It is the light of God in which "we also shall see light." In proportion as we rise to the knowledge of the revelation of God in Christ, all the vast realm of thought will appear in its true character and proportions before us; for the God-man is, in every sense, the light of the world.

4. The jasper wall is, further, representative of the defence of the city. The need of defence against attack was probably the earliest reason for the construction of the ancient city walls, the other ideas of which we have spoken having afterwards grown upon this underlying one. So the ideal city is safe for ever, guarded by this wall of jasper, which is great and high. No battering ram can beat down these walls, for they are constructed out of the mightiest forces of omnipotence, the forces of eternal grace and infinite love.

II. A few words will suffice to show the relation of the jasper wall to the foundations of the city. The first thing that strikes us as impressively suggestive is the fact that the deepest base of the city and its towering walls are composed of the same material. When we begin to search for the strength of the twelve foundations, John meets us with the assertion: "The foundation is jasper." When we raise our eyes to behold its lofty ramparts, and would fain know what its topmost glory is that mingles with the skies, John again says: "The building of the wall thereof was jasper." It is the symbolic representation of the utterance of the Divine Saviour, who says: "I am the Alpha and the Omega, the first and the last, the beginning and the end." In Christ, the effulgence of the Father's glory, the first foundations are laid of the city of a glorified human life, and in Him its final splendour will be realised. The name of Jesus is the all-potent source of new life for the fallen sons of earth, and it shall be the eternal boast and wonder of the glorified. As is the lowest foundation of the holy city, so shall be its supremest splendour. The Cross can never be superseded. The wall of jasper is a living growth out of the foundations of precious stones. This living relation in the growth of the ideal city is determined by eternal and inexorable law. The city's jasper wall cannot be built unless the foundations are set in precious stones, and the deepest of these is jasper. Passing from symbolic language to plainer speech, the quality of a city's life cannot rise higher than its deepest foundations. The nature of the principles and ideals upon which men proceed will determine the value and permanence of such a social life as they are likely to create. Upon foundations of iron and brass nothing better than iron and brass can ever be built. If our ideals fall short of the divinest that are possible to men, if our deepest principles fall short of the glory of the eternal skies, then the building of the ideal city becomes for ever impossible for us. On the other hand, the foundations of precious stones cannot fail to issue in the wall of jasper. "When Divine forces form the base, the city is certain to rise in the likeness of God. Out of the love of the Cross a kingdom of love shall of necessity grow. All ye that desire to build the jasper wall, remember that it cannot be built except on the jasper foundation.

III. There are one or two points remaining in the characterisation of the jasper wall which must receive brief notice. One consists in the measurement of the thickness of the wall, which is declared to be a hundred and forty and four cubits — that is, twelve cubits by twelve. This is clearly, once more, the number that symbolises redemption, and so brings the thickness of the city-wall into line with the twelve thousand furlongs that measure the length and breadth and height of it. In the last place, it is instructive to note that the city when measured proves to be an exact cube. "The length and the breadth and the height thereof are equal." The cube has from ancient times been regarded as a symbol of ideal perfection. Here human life is at last full and complete, having found the complete cycle of its power. Probably, however, John's picture is more immediately connected with the form of the "holy of holies" in the tabernacle, which was also a perfect cube, no doubt based upon the ancient idea of that form as being specially perfect and sacred.
