Wayne Jackson has an interesting biblical analysis of the JW position on Armadeddon at Christian Courier.

A sample:

In Matthew 24:5ff, Christ set forth a number of “signs” that would herald the impending destruction of Jerusalem. He plainly declared: “this generation shall not pass away, till all these things be accomplished” (v. 34). Of special interest are the expressions “this generation,” and “all.”

The word “generation” (genea) refers to “the sum total of those born at the same time, expanded to include all those living at a given time and freq[uently] defined in terms of specific characteristics, generation, contemporaries” (F.W. Danker, et al., Greek-English Lexicon of the New Testament and Other Early Christian Literature, Chicago: University of Chicago, 2000, p. 191).

The expression “this generation” (he-genea-aute) is found five times in Matthew’s Gospel record, and never is it employed in any sense other than that of the “generation” contemporary with Jesus Christ (cf. 11:16; 12:41-42; 23:36).

The “Witnesses,” however, assign a most strange interpretation to the phrase. They contend: “It is the generation of people who saw the catastrophic events that broke forth in connection with World War I from 1914 onward” (Watchtower, op. cit., p. 31).

The fact of the matter is, however, the “Watchtower” folks concede that Christ’s application was to the destruction of Jerusalem by the Romans in A.D. 70. “[Christ] outlined things that would befall the Jewish nation during the execution of Jehovah’s judgment upon Jerusalem at the hands of the Roman general Titus (Dan. 9:26)” (Aid to Bible Understanding, Brooklyn, NY: Watchtower Society, 1971, p. 642).

Incredibly, however, they manipulate the expression “this generation” across more than 2,000 years of history to embrace the modern era. Further, they totally ignore the Lord’s declaration that “all” the signs of Matthew 24:5-33 were to be fulfilled in the A.D. 70 event. The common-sense rules of responsible exegesis are thrust aside with reckless abandon.

I have one quibble with the piece. Anyone who refers to the JWs as a “non-prophet” enterprise is correct only in the literal sense. Lack of prophetic vision, yes.

But it’s no fun without the pun, and JWs are not non-profit – far from it.

Note for researchers – “Watchtower” is written as a single word in the name of the sect’s New York corporation, but as two words in the name of the Pennsylvania parent corporation.
