Narkissos:
As to the text under discussion, and especially the time connection of the Jerusalem "great tribulation" and the "sign of the Son of Man," it is noteworthy that the typically Markan eutheƓs ("immediately") occurs in the extant text of Matthew (24:29), not in Mark!
While many debate over what "immediately" means to try to adjust their own understanding, the chronologist doesn't have to. That's because the "great tribulation" here was the Holocaust. The Holocaust ends in 1945 but the Jews are not restored to their new homeland until 1947, the official end of the "appointed times of the nations." What happens "immediately" after this is the spiritual darkness of the Watchtower Society. This is the time when the "ten virgins" (also representing the anointed ones of the WTS) nod and their lamps begin to dim. That means they would not know completely the details of the secretive second coming of the messiah.
Even so, others would begin to see the "sign of the son of man." A representation of the sign of the son of man, which is a sleeping black child seen in the clouds next to a bird-like figure, a dove or more likely an eagle is represented in the "Revelation" book which was published in 1988. But the actual second coming does not occur until 45 years after 1947 in 1992. Therefore, that "sign" likely began rather "immediately" after the end of that great tribulation as well. Exactly when? I'm not sure. But likely around the time of the birth of the second coming messiah. That is, the person who would become a witness, live the life of the prodigal son and upon returning at the last minute become the messiah ahead of his faithful older brothers (i.e. the older faithful anointed ones in the WTS).
So it happened just as the Bible says. After the Holocaust the sign began to appear. The messiah would be tested for 40 years before being redesignated as the messiah, arriving for that purpose at the beginning of the 70th week which is 1989-1996. In that case the sign may have begun to appear as early as mid-1949, less than two years after November 30, 1947.
The sign appears to the holy ones who are watching the life of the messiah. The prodigal son messiah is thus spoken of as a CORPSE: "Where the corpse is, so the eagles will be gathered." The prodigal son messiah is not aware that he is the messiah until he actually becomes the messiah, but the "eagles" that expect him are aware of him and follow and intervene in his life as necessary.
There's no need to twist the scriptures when you have both truth and reality.
