And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. For these be the days of vengeance, that all things which are written may be fulfilled. But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people. And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
Luke 21:20-23
The argument of “all things which are written” stems verse 22 in this passage, that the Great Tribulation, the Days of Vengeance, would be in fulfillment of all that has been written. The conjecture is that the context “all things that are written” pertains to all of scriptural prophecy ever, and not simply to “all things that are written” pertaining to the particular destruction. This argument is simply defeated by the Olivet Discourse.
In Matthew 24, Jesus describes the destruction of Jerusalem, the Great Tribulation, which was worse than any other trial both before or since. In verse 29, He then describes what will “next but after” that time happen.
Since the “next but after” is after the Days of Vengeance described above, and the events described after are written about in scripture, the “All things that are written” can obviously not pertain to those things which are “next but after”. Hence, “all things that are written”, as the logic of the sentence indicates, simply applies to all the things written about the days of vengeance pertaining to the destruction of Jerusalem. There simply is no need to extend the “all” in this passage to mean anything else, and to do so would clearly be contradictory of the rest of Scripture. Doing so is merely a furturist’s attempt to force all of prophetic history into a yet to be disclosed time frame, and has no hermenutical worth.
