Zechariah was the Prophet of the returning exiles, and his great work was to hearten them for their difficult task, with their small resources and their many foes, and to insist that the prime condition to success, on the part of that portion of the nation that had returned, was holiness. So his visions, of which there is a whole series, are very largely concerned with the building of the Temple and of the city. In this one, he sees a man with a measuring-rod in his hand coming forth to take the dimensions of the still un-existing city of God. The words that I have read are the centre portion of that vision. You notice that there are three clauses, and that the first in order is the consequence of the other two. 'Jerusalem shall be builded as a city without walls ... for I will be a wall of fire round about her, and the glory in the midst of her.'
And that exuberant promise was spoken about the Jerusalem over which Christ wept when he foresaw its inevitable destruction. When the Romans had cast a torch into the Temple, and the streets of the city were running with blood, what had become of Zechariah's dream of a wall of fire round about her? Then can the divine fire be quenched? Yes. And who quenched it? Not the Romans, but the people that lived within that flaming rampart. The apparent failure of the promise carries the lesson for churches and individuals to-day, that in spite of such glowing predictions, there may again sound the voice that the legend says was heard within the Temple, on the night before Jerusalem fell. 'Let us depart,' and there was a rustling of unseen wings, and on the morrow the legionaries were in the shrine. 'If God spared not the natural branches, take heed lest He also spare not thee.'
Now let us look, in the simplest possible way, at these three clauses, and the promises that are in them; keeping in mind that, like all the divine promises, they are conditional.
The first is this: --
I. 'I will be a wall of fire round about her.'
I need not dwell on the vividness and beauty of that metaphor. These encircling flames will consume all antagonism, and defy all approach. But let me remind you that the conditional promise was intended for Judaea and Jerusalem, and was fulfilled in literal fact. So long as the city obeyed and trusted God it was impregnable, though all the nations stood round about it, like dogs round a sheep. The fulfilment of the promise has passed over, with all the rest that characterised Israel's position, to the Christian Church, and to-day, in the midst of all the agitations of opinion, and all the vauntings of men about an effete Christianity, and dead churches, it is as true as ever it was that the living Church of God is eternal. If it had not been that there was a God as a wall of fire round about the Church, it would have been wiped off the face of the earth long ago. If nothing else had killed it the faults of its members would have done so. The continuance of the Church is a perpetual miracle, when you take into account the weakness, and the errors, and the follies, and the stupidities, and the narrownesses, and the sins, of the people who in any given day represent it. That it should stand at all, and that it should conquer, seems to me to be as plain a demonstration of the present working of God, as is the existence still, as a separate individuality amongst the peoples of the earth, of His ancient people, the Jews. Who was it who said, when somebody asked him for the best proof of the truth of Christianity, 'The Jews'? and so we may say, if you want a demonstration that God is working in the world, 'Look at the continuance of the Christian Church.'
In spite of all the vauntings of people that have already discounted its fall, and are talking as if it needed no more to be reckoned with, that calm confidence is the spirit in which we are to look around and forward. It does not become any Christian ever to have the smallest scintillation of a fear that the ship that bears Jesus Christ can fail to come to land, or can sink in the midst of the waters. There was once a timid would-be helper who put out his hand to hold up the Ark of God. He need not have been afraid. The oxen might stumble, and the cart roll about, but the Ark was safe and stable. A great deal may go, but the wall of fire will be around the Church. In regard to its existence, as in regard to the immortal being of each of its members, the great word remains for ever true: 'Because I live ye shall live also.'
But do not let us forget that this great promise does not belong only to the Church as a whole, but that we have each to bring it down to our own individual lives, and to be quite sure of this, that in spite of all that sense says, in spite of all that quivering hearts and weeping eyes may seem to prove, there is a wall of fire round each of us, if we are keeping near Jesus Christ, through which it is as impossible that any real evil should pass and get at us, as it would be impossible that any living thing should pass through the flaming battlements that the Prophet saw round his ideal city. Only we have to interpret that promise by faith and not by sense, and we have to make it possible that it shall be fulfilled by keeping inside the wall, and trusting to it. As faith dwindles, the fiery wall burns dim, and evil can get across its embers, and can get at us. Keep within the battlements, and they will flame up bright and impassable, with a fire that on the outer side consumes, but to those within is a fire that cherishes and warms.
II. The next point of the promise passes into a more intimate region. It is well to have a defence from that which is without us; but it is more needful to have, if a comparison can be made between the two, a glory 'in the midst' of us.
The one is external defence; the other inward illumination, with all which light symbolises -- knowledge, joy, purity.
There is even more than that meant by this great promise. For notice that emphatic little word the -- the glory, not a glory -- in the midst of her. Now you all know what 'the glory' was. It was that symbolic Light that spoke of the special presence of God, and went with the Children of Israel in their wanderings, and sat between the Cherubim. There was no 'Shechinah,' as it is technically called, in that second Temple. But yet the Prophet says, 'The glory' -- the actual presence of God -- 'shall be in the midst of her,' and the meaning of that great promise is taught us by the very last vision in the New Testament, in which the Seer of the Apocalypse says, 'The glory of the Lord did lighten it' (evidently quoting Zechariah), 'and the Lamb is the light thereof.' So the city is lit as by one central glow of radiance that flashes its beams into every corner, and therefore 'there shall be no night there.'
Now this promise, too, bears on churches and on individuals. On the Church as a whole it bears in this way: the only means by which a Christian community can fulfil its function, and be the light of the world, is by having the presence of God, in no metaphor, the actual presence of the illuminating Spirit in its midst. If it has not that, it may have anything and everything else -- wealth, culture, learning, eloquence, influence in the world -- but all is of no use; it will be darkness. We are light only in proportion as we are 'light in the Lord.' As long as we, as communities, keep our hearts in touch with Him, so long do we shine. Break the contact, and the light fades and flickers out.
The same thing is true, dear brethren, about individuals. For each of us the secret of joy, of purity, of knowledge, is that we be holding close communion with God. If we have Him in the depths of our hearts, then, and only then, shall we be 'light in the Lord.'
And now look at the last point which follows, as I have said, as the result of the other two.
III. 'Jerusalem shall be without walls.'
It is to be like the defenceless villages scattered up and down over Israel. There is no need for bulwarks of stone. The wall of fire is round about. The Prophet has a vision of a great city, of a type unknown in those old times, though familiar to us in our more peaceful days, where there was no hindrance to expansion by encircling ramparts, no crowding together of the people because they needed to hide behind the city walls; and where the growing community could spread out into the outer suburbs, and have fresh air and ample space. That is the vision of the manner of city that Jerusalem was to be. It did not come true, but the ideal was this. It has not yet come true sufficiently in regard to the churches of to-day, but it ought to be the goal to which they are tending. The more a Christian community is independent of external material supports and defences the better.
I am not going to talk about the policy or impolicy of Established Churches, as they are called. But it seems to me that the principle that is enshrined in this vision is their condemnation. Never mind about stone and lime walls, trust in God and you will not need them, and you will be strong and 'established' just in the proportion in which you are cut loose from all dependence upon, and consequent subordination to, the civil power.
But there is another thought that I might suggest, though I do not know that it is directly in the line of the Prophet's vision; and that is -- a Christian Church should neither depend on, nor be cribbed and cramped by, men-made defences of any kind. Luther tells us somewhere, in his parabolic way, of people that wept because there were no visible pillars to hold up the heavens, and were afraid that the sky would fall upon their heads. No, no, there is no fear of that happening, for an unseen hand holds them up. A church that hides behind the fortifications of its grandfathers' erection has no room for expansion; and if it has no room for expansion it will not long continue as large as it is. It must either grow greater, or grow, and deserve to grow, less.
The same thing is true, dear brethren, about ourselves individually. Zechariah's prophecy was never meant to prevent what he himself helped to further, the building of the actual walls of the actual city. And our dependence upon God is not to be so construed as that we are to waive our own common-sense and our own effort. That is not faith; it is fanaticism.
We have to build ourselves round, in this world, with other things than the 'wall of fire,' but in all our building we have to say, 'Except the Lord build the house, they labour in vain that build it. Except the Lord keep the city, the watchers watch in vain.' But yet neither Jerusalem nor the Church, nor the earthly state of that believer who lives most fully the life of faith, exhausts this promise. It waits for the day when the city shall descend, 'like a bride adorned for her husband, having no need of the sun nor of the moon, for the glory ... lightens it.' Having walls, indeed, but for splendour, not for defence; and having gates, which have only one of the functions of a gate -- to stand wide open, to the east and the west, and the north and the south, for the nations to enter in; and never needing to be barred against enemies by day, 'for there shall be no night there.'
