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.
