'And had a wall.' Having thus, I say, given us a description of this city in general, he now descends to her strength and frame in particular: her frame and strength, I say, as she is a city compact together: as also of her splendour and beauty.
And observe it, that of all the particulars that you read of, touching the fence, fashion, or frame of this city, and of all her glory, the firs thing that he presenteth to our view is her safety and security; she 'had a wall.' A wall, you know, is for the safety, security, defence, and preservation of a place, city, or town; therefore it is much to the purpose that in the first place after this general description, he should fall upon a discovery of her security and fortification; for what of all this glory and goodness, if there be no way to defend and preserve it in its high and glorious state? If a man had in his possession even mountains of pearl and golden mines, yet if he had not wherewith to secure and preserve them to himself, from those that with all their might endeavour to get them from him, he might not only quickly lose his treasure, and become a beggar, but also through the very fear of losing them, even lose the comfort of them, while yet in his possession. To speak nothing of the angels that fell, and of the glory that they then did lose. I may instance to you the state of Adam in his excellency; Adam, you know, was once so rich and wealthy, that he had the garden of Eden, the paradise of pleasure, yea, and also the whole world to boot, for his inheritance; but mark, in all his glory, he was without a wall; wherefore presently, even at the very first assault of the adversary, he was not only worsted as touching his person and standing, but even stripped of all his treasure, his paradise taken from him, and he in a manner left so poor, that forthwith he was glad of an apron of fig-leaves to cover his nakedness, and to hide his shame form the face of the sun (Gen 3:7). Wherefore, I say, John speaks to the purpose in saying she had a wall; a wall for defence and safety, for security and preservation. Now then she shall lie no longer like blasted bones in an open field or valley; that was her portion in the days of her affliction (Eze 37:1,2).
[The wall of the city.]
'And had a wall.' It is said of old Jerusalem, that she had a wall and a wall, two walls for her defence and safety (Jer 39:4; Jer 52:7); which two, in my judgment, did hold forth these two things. The one, their eternal preservation and security from the wrath of God, through the benefits of Christ; and the other, that special protection and safeguard that the church hath always had from and by the special providence of her God in the midst of her enemies, Wherefore one of these is called by the proper name of salvation, which salvation I take in special to signify our fortification and safety from the wrath of God, and the curse and power of the law and sin (Isa 26:1; Acts 4:12). The other is called, A wall of fire round about her; and alludeth to the vision that the prophet's servant was made to see for his comfort, when he was put in fear, by reason of the great company of the enemies that were bending their force against the life of his master (Eze 2:5; 2 Kings 6:17).
But now in those days, though there were for the defence of the city those two walls, yet they stood a little distance each from other, and had a ditch between them, which was to signify that though then they had the wall of salvation about them, with reference to their eternal state, yet the wall of God's providence and special protection was not yet so nearly joined thereto but that they might, for their foolishness, have that broken down, and they suffered to fall into the ditch that was between them both (Isa 22:10-12). And so he saith by the prophet, 'I will tell you what I will do to my vineyard [that is, to this city for the wickedness thereof], I will take away the hedge thereof, and it shall be eaten up; and break down the wall thereof, and it shall be trodden down' (Isa 5:5-7). Which hedge and wall could not be that of eternal salvation, for that stood sure, though they should be scattered among the nations 'as wheat is sifted in a sieve' (Amos 9:9). It must therefore be the wall of her special preservation in her outward peace and happiness, which wall was often in those days broken down, and they made havoc of, of all that dwelt about them.
But now touching the safety of New Jerusalem, the city of which I here discourse, she is seen in the vision by John to have but one only wall; to signify that at this day the wall of her eternal salvation, and of God's special providence to protect and defend her, in her present visible and gospel glory, shall be so effectually joined together, that now they shall be no more two, that is, at a distance, with a ditch between, but one sound and enclosing wall; to show us that now the state of this Jerusalem, even touching her outward glory, peace, and tranquility, will be so stable, invincible, and lasting, that unless that part of the wall which is eternal salvation, can be broken down, the glory of this city shall never be vailed more. Wherefore the prophet, when he speaks with reference to the happy state and condition of this city, he saith, 'Violence shall no more be heard in thy land, wasting nor destruction within thy borders; but thou shalt call thy walls salvation, and thy gates praise' (Isa 60:18); as he saith also in another place, 'Thine eye shall see Jerusalem a quiet habitation, a tabernacle that shall not be taken down, not one of the stakes thereof shall ever be removed, neither shall any of the cords thereof be broken' (Isa 33:20). The walls are now conjoined, both joined into one; the Father hath delivered up the great red dragon into the hand of Christ, who hath shut him up and sealed him down, even down for a thousand years (Rev 20:1-3). Wherefore from the Lord shall there be 'upon every dwelling-place of Mount Zion, and upon her assemblies a cloud and smoke by day, and the shining of a flaming fire by night; for upon all her glory shall be a defence' (Isa 4:5). And 'in that day shall this song be sung: We have a strong city, salvation will God appoint for walls and bulwarks' (Isa 26:1,2). The same in effect hath our prophet John, saying 'I saw the holy city, the New Jerusalem,' descending out of heaven from God, 'prepared as a bride adorned for her husband. And I heard a great voice out of heaven, saying,—The tabernacle of God is with men, and he will dwell with them:—and God himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying; neither shall there be any more pain; for the former things are passed away' (Rev 21:1-4).
'And had a wall great and high.' These words, great and high, are added for illustration, to set out the matter to the height; and indeed the glory of a wall lieth in this, that it is great and high; the walls of the Canaanites were terrible upon this account, and did even sink the hearts of those that beheld them (Deu 1:28). Wherefore this city shall be most certainly in safety, she hath a wall about her, a great wall: a wall about her, an high wall. It is great for compass, it incloseth every saint; it is great for thickness, it is compacted of all the grace and goodness of God, both spiritual and temporal; and for height, if you count from the utmost side to the utmost, then it is higher than heaven, who can storm it? (Heb 7:26) and for depth, it is lower than hell, who can undermine it? (Job 11:8).
Great mercies, high mercies, great preservation, and a high arm to defend, shall continually at this day encamp this city: God himself will be a continual life-guard to this city; 'I will encamp,' saith he, 'about mine house, because of the army, because of him that passeth by, and because of him that returneth; and no oppressor shall pass through them any more; for now have I seen with mine eyes' (Zech 9:8).
[The gates of the city.]
'And had twelve gates.' Having thus showed us her wall, he now comes to her gates; it had gates, it had twelve gates. By gates in this place we are to understand the way of entrance; gates, you know, are for coming in, and for going out (Jer 17:19,20); and do in this place signify two things. First, An entrance into communion with the God and Saviour of this city. Secondly, Entrance into communion with the inhabitants and privileges of this city; in both which the gates do signify Christ: for as no man can come to the knowledge and enjoyment of the God, and glorious Saviour, but by and through the Lord Christ; so no man can come into true and spiritual communion with these inhabitants, but by him also: 'I am the way,' saith he, 'and the truth, and the life; no man cometh unto the Father but by me': and again, 'I am the door, by me if any man enter in, he shall be saved, and shall go in and out, and find pasture' (John 10:1-9; 14:6).
