“Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken.” (Matt 24:29).

Historicism is the eschatological position that says the thrust of prophecy in the Olivet Discourse and Revelation are fulfilled in the span of the church age. So for example, they would say that the Great Tribulation was not fulfilled in the first century, nor is it to be fulfilled in the future. Instead, it spans the entire church age.
You may by surprised to learn that most Evangelical scholars are not preterists or futurists—they are historicists. But many are a mixture of preterist-historicist. Or, more inconsistently, some are preterist-historicist-futurist.
There are good reasons why historicism is not a valid interpretation. I want to point out one salient reason here. In Matthew’s account of the Olivet discourse in Matthew 24:29 he uses the Greek term έὐθέως, which means “immediately.” The event that follows the “tribulation (i.e. great tribulation) of those days” is the coming of Christ. Matthew says that the coming of Christ will occur immediately after the tribulation of those days. What is the nature of this tribulation? We are told specifically that this tribulation is caused by the abomination of desolation (Cf. Matt. 24:15, 21).
So historicism cannot be correct for two reasons:
i. The tribulation will come about by the abomination of desolation. So this tribulation cannot be described as occurring over the span of the church age. That is, believers are not going through tribulation today because the Roman general Titus destroyed the Jewish temple in A.D. 70.
ii. Since historicism believes that the abomination of desolation in Matthew 24 was fulfilled in A.D. 70 with the destruction of the temple followed by tribulation, έὐθέως (immediately) must refer specifically to that tribulation, since the term has a temporal meaning requiring that the coming of Christ to occur in the first century. In other words, it is nonsense for them to claim as they do that “immediately” will happen thousands of years later after the abomination of desolation. Therefore historicism has a strained interpretation.
Prewrath has the natural reading. We understand that the abomination of desolation for Matthew refers to a futurist event of Antichrist in the temple. That will cause a great tribulation and immediately after those days are cut short the coming of Christ will happen.
