But though the destruction of Jerusalem is the primary subject of the prophecy, in its full sweep it takes a far wider range. The Saviour sees before Him with prophetic eye, not only that great event which was to be the end of the world which then was—the close of the dispensation of grace which had lasted two thousand years; but also the end of all things, when the last dispensation of grace—not for Israel alone, but for the whole world—shall have come to a close. Though these two events were to be separated from each other by a long interval of time, yet were they so closely related in their nature and issues that our Lord, having in view the needs of those who were to live in the new dispensation, could not speak of the one without also speaking of the other. What He was then saying was intended for the guidance, not only of the disciples then around Him, and of any other Jews who might from them receive the message, but also for the guidance of the whole Christian Church throughout the world to the end of time,—another marvellous illustration of that sublime consciousness of life and power, infinitely beyond the limits of His mere manhood, which is ever betraying itself throughout this wondrous history. Had He confined Himself to the destruction of Jerusalem, His words would have had no special interest for us, any more, for example, than the burden of Babylon or of Tyre or of Dumah in the Old Testament Scriptures; but when He carries us on to that Last Great Day, of which the day of Jerusalem's destruction (as closing the Old Testament dispensation) was a type, we recognise at once our own personal interest in the prophecy; for we ourselves are individually concerned with that Day—we shall then either be overwhelmed in the ruins of the old, or shall rejoice in the glories of the new; therefore we should feel that this prophecy has an interest for us as personal as it had for those who first heard it on the Mount of Olives.

As might be expected from the nature of its subject, the interpretation of the prophecy in matters of detail is beset with difficulties. The sources of difficulty are sufficiently obvious. One is in the elimination of time. The time of both events is studiously concealed, according to the principle distinctly announced by our Saviour just before His ascension: "It is not for you to know the times or the seasons, which the Father hath put in His own power." There are in each case signs given, by which the approach of the event may be recognised by those who will give heed to them; but anything in the shape of a date is studiously avoided. It is perhaps not too much to say that nine-tenths of the difficulties which have been encountered in the interpretation of this passage have arisen from the unwarrantable attempts to introduce dates into it.

Another difficulty arises from the similarity of the two events referred to, and the consequent applicability of the same language to both of them. This leads to different opinions as to which of the two is referred to in certain places. To show the source of these difficulties is to suggest their solution; for when we consider that one event is the type of the other, that one is as it were the miniature of the other, the same on a much smaller scale, we need not hesitate to apply the same language to both,—it may be literally in the one case and figuratively in the other; or it may be in a subordinate sense in the one case, and in the fullest sense in the other; or it may be in precisely the same sense in both cases. In general, however, it will be observed that the lesser event—the destruction of Jerusalem—stands out in full prominence in the beginning of the prophecy, and the greater event—the Great Day of our Saviour's appearing—in the latter part of it.

Still another source of difficulty is that, while our Saviour's object in giving the prophecy was practical, the object of many who study the prophecy is merely speculative. They come to it to satisfy curiosity, and as a matter of course they are disappointed, for our Lord did not intend when He spoke these words to satisfy so unworthy a desire; and, though His word never returns to Him void, it accomplishes that which He pleases, and nothing else; it prospers in the thing to which He has sent it, but not in the thing to which He has not sent it. He has sent us this, not to satisfy our curiosity, but to influence our conduct; and if we use it not for speculative but for practical purposes—not to find support for any favourite theory, which parcels out the future, giving days and hours, which neither the angels in heaven nor the Son of man Himself could tell (Mark xiii. 32)—but to find food for our souls, then we shall not be troubled with so many difficulties, and we shall certainly not be disappointed.

Before we pass from the difficulties of this prophecy, observe how strong an argument they furnish for its genuineness. Those who deny the divinity of Christ are greatly troubled with this prophecy, so much so that the only way in which they can get rid of its witness to Him is by suggesting that it was really composed after the destruction of Jerusalem, and therefore never spoken by Christ at all. There are difficulties enough of other kinds in the way of such a disposal of the prophecy; but there is one consideration which absolutely forbids it—viz., that any one writing after the event would have avoided all that vagueness of language which gives trouble to expositors. To those who can judge of internal evidence, its obscurity is clear proof that this discourse could not have been produced in the full light of the subsequent history, but must have been what it professes to be, a foreshadowing of coming events.

We may not, with the limits imposed by the plan of these expositions, attempt a detailed explanation of this difficult prophecy, but must content ourselves with giving only a general view. Our Lord first warns His disciples against expecting the crisis too early (vv. 4-14). In this passage He prepares the minds of His disciples for the times of trouble and trial through which they must pass before the coming of "the great and notable day of the Lord" which was at hand: there shall be false Christs and false prophets—there shall be wars and rumours of wars, and shaking of the nations, and famines, and pestilences, and earthquakes in divers places; yet will all these be only "the beginning of sorrows." He also prepares their minds for the gigantic work which must be done by them and by their brother-disciples before that great day: "This gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come." Thus are the disciples taught the very important and thoroughly practical truth, that they must pass through a great trial and do a great work before the Day shall come.

He then gives them a certain sign by which they shall know that the event is imminent, when it does approach. This is not equivalent to fixing a date. He gives them no idea how long the period of trial shall last, no idea how long time they shall have for the great work before them—He simply gives them a sign, by observing which they shall not be taken completely by surprise, but have at least a brief space to make their escape from the condemned city. And so very little time will elapse between the sign and the event to which it points, that He warns them against any delay, and tells them, as soon as it shall appear, to flee at once to the mountains and escape for their lives. It is sufficiently evident, by comparing this passage with the corresponding place in Luke, where our Lord speaks of Jerusalem being compassed with armies, that the "abomination of desolation standing in the holy place" refers to some particular act of sacrilegious impiety committed in the Temple just at the time the Romans were beginning to invest the city. Attempts have been made historically to identify this profanation, but it is doubtful if these have been successful. It is sufficient to know that whether or not the fact has found a place in history, it served its purpose as a sign to the Christians in the city who had treasured up in their hearts their Saviour's warning words.

Having told them what the sign would be, and counselled His disciples to lose no time in making their escape as soon as they should see it, He further warns them, in a few impressive words, of the terrors of those days of tribulation (vv. 19-22), and then concludes this portion of the prophecy by warning them against the supposition—a very natural one in the circumstances—that even then the Son of man should come.

So far we have found the leading ideas to be simple and practical, and all connected with the destruction of Jerusalem. (1) Do not expect that event too early; for you must pass through many trials and do much work before it. (2) As soon as you shall see the sign I give you, expect it immediately, and lose no time in making your escape from the horrors of these awful days. (3) Even then, however, do not expect the personal advent of the Son of man; for though it is a day of judgment, it is only one of those partial judgments which are necessary on the principle that "wheresoever the carcase is, there will the eagles be gathered together." The personal advent of Christ and the day of final judgment are only foreshadowed by, not realised in, the destruction of Jerusalem and the close of the old dispensation.

The three closing verses of this portion of the prophecy refer pre-eminently to the great Day of the coming of the Son of man (vv. 29-31). The word "immediately" has given rise to much difficulty, on account of the hasty conclusion to which some have come that "immediately after the tribulation of those days" must mean immediately after the destruction of Jerusalem; according to which all this must have taken place long ago. It is, indeed, sufficiently obvious that the tribulation of those days began with the destruction, or rather with the besieging, of Jerusalem. But when did it end? As soon as the city was destroyed? Nay. If we wish to get some idea of the duration of those days of tribulation, let us turn to the same place in the same prophecy as given by St. Luke (xxi. 23, 24), where it clearly appears that it embraces the whole period of the Jewish dispersion and of the standing of the Gentile Church. "The tribulation of those days" is going on still, and therefore the events of these verses are still future. We look forward to the Day of the Lord of which that terrible day of judgment, to which their thoughts were first turned, was only a dim foreshadowing—a Day far more august in its nature, far more awful in its accompaniments, far more terrible in its aspect to those who are unprepared for it, yet full of glory and of joy to those who "love His appearing."
