(35) Heaven and earth.--The tone is that of One who speaks with supreme authority, foreseeing, on the one hand, death and seeming failure, but on the other, the ultimate victory, not of truth only in the abstract, but of His own word as the truth. The parallelism of the words with those of Psalm 102:26, Isaiah 40:8, gives them their full significance. The Son of Man claims for His own words the eternity which belongs to the words of Jehovah. (Comp. 1Peter 1:24-25.) The whole history of Christendom witnesses to the fulfilment of the prophetic claim. Amid all its changes and confusions, its errors and its sins, the words of Christ have not passed away, but retain their pre-eminence as the last and fullest revelation of the Father.

Verse 35. - Christ adds a solemn assurance that his words have in them a vitality and endurance which the mightiest works of nature do not possess. The facts and truths embodied in his words are sure and steadfast, and what he has promised or predicted shall inevitably be fulfilled. This verse is omitted by א but it is most probably genuine, as it undoubtedly has its place in the other two synoptists (comp. 1 Peter 1:24, 25).

24:29-41 Christ foretells his second coming. It is usual for prophets to speak of things as near and just at hand, to express the greatness and certainty of them. Concerning Christ's second coming, it is foretold that there shall be a great change, in order to the making all things new. Then they shall see the Son of man coming in the clouds. At his first coming, he was set for a sign that should be spoken against, but at his second coming, a sign that should be admired. Sooner or later, all sinners will be mourners; but repenting sinners look to Christ, and mourn after a godly sort; and those who sow in those tears shall shortly reap in joy. Impenitent sinners shall see Him whom they have pierced, and, though they laugh now, shall mourn and weep in endless horror and despair. The elect of God are scattered abroad; there are some in all places, and all nations; but when that great gathering day comes, there shall not one of them be missing. Distance of place shall keep none out of heaven. Our Lord declares that the Jews should never cease to be a distinct people, until all things he had been predicting were fulfilled. His prophecy reaches to the day of final judgment; therefore he here, ver. 34, foretells that Judah shall never cease to exist as a distinct people, so long as this world shall endure. Men of the world scheme and plan for generation upon generation here, but they plan not with reference to the overwhelming, approaching, and most certain event of Christ's second coming, which shall do away every human scheme, and set aside for ever all that God forbids. That will be as surprising a day, as the deluge to the old world. Apply this, first, to temporal judgments, particularly that which was then hastening upon the nation and people of the Jews. Secondly, to the eternal judgment. Christ here shows the state of the old world when the deluge came. They were secure and careless; they knew not, until the flood came; and they believed not. Did we know aright that all earthly things must shortly pass away, we should not set our eyes and hearts so much upon them as we do. The evil day is not the further off for men's putting it far from them. What words can more strongly describe the suddenness of our Saviour's coming! Men will be at their respective businesses, and suddenly the Lord of glory will appear. Women will be in their house employments, but in that moment every other work will be laid aside, and every heart will turn inward and say, It is the Lord! Am I prepared to meet him? Can I stand before him? And what, in fact, is the day of judgment to the whole world, but the day of death to every one?Heaven and earth shall pass away,.... This is either an assertion, which will be true at the end of time; not as to the substance of the heavens and earth, which will always remain, but as to the qualities of them, which will be altered: they will be renewed and refined, but not destroyed; the bad qualities, or evil circumstances, which attend them through the sin of man, will be removed and pass away, but they themselves will continue in being: or is a comparative expression, and the sense is, that the heavens and the earth, and the ordinances thereof, than which nothing can be more firm and strong, being fixed and supported by God himself, shall sooner pass away, than anything asserted and predicted by Christ shall:

but my words shall not pass away; be vain and empty, and unaccomplished; which is true of anything, and everything spoken by Christ; and especially here regards all that he had said concerning the calamities that should befall the Jews, before, at, or upon the destruction of their nation, city, and temple; and the design of the expression, is to show the certainty, unalterableness, and sure accomplishment of these things; see Jeremiah 31:36.
