Well, yes. Revelation is merely a dressed up version of Mat. 24 mentioned in the gospels, but not John’s. The returning would be witnessed by that generation. Revelation says the ones who pierced Christ on the cross would see it.
Back when I was much younger and had more time, I would neglect reading the New Testament, for the Old, because the writers were always mentioning that they were living in the end times, and that the return of Christ was near. In fact, the belief was so prevalent that Paul had to write a letter explaining to the Church that the second coming had not taken place, yet. Therefore, that we were supposed to be living in the end times always uncomfortably puzzled me. I did not know there was a school of thought that taught differently than the way I was taught.
