The paragraphs on "this generation" include the following:
17. What is the meaning of the expressions “generation” and “all these things”?
17 “Will by no means pass away until all these things happen.” How will those words prove true? To answer that, we need to know two things: the meaning both of “generation” and of “all these things.” The term “generation” often refers to people of varying ages whose lives overlap during a particular period of time. A generation is not overly long, and it comes to an end. (Ex. 1:6) The expression “all these things” includes all the foretold events during Jesus’ presence, from its beginning in 1914 until its culmination at the “great tribulation.”—Matt. 24:21.
18, 19. How may we understand Jesus’ words about “this generation,” and what may we conclude?
18 How, then, may we understand Jesus’ words about “this generation”? The generation consists of two overlapping groups of anointed ones—the first is made up of anointed ones who saw the beginning of the fulfillment of the sign in 1914 and the second, anointed ones who for a time were contemporaries of the first group. At least some of those in the second group will live to see the beginning of the coming tribulation. The two groups form one generation because their lives as anointed Christians overlapped for a time. *
19 What may we conclude? Well, we know that the sign of Jesus’ presence in Kingdom power is clearly evident around the globe. We also see that the anointed ones who are still alive and part of “this generation” are getting on in years; yet, they will not all die off before the great tribulation begins. Therefore, we can conclude that very soon indeed God’s Kingdom will come and exercise its rule over the earth! How thrilling it will be to witness the fulfillment of the prayer that Jesus taught us: “Let your Kingdom come”!
Interesting to note that there is NO EXPLANATION of how they have arrived at this conclusion, NO REASONING and NO SCRIPTURES used to support the overlapping theory.
The scripture in Exodus simply refers to Joseph, his brothers and his contemporaries:
6 Joseph eventually died, and also all his brothers and all that generation.
How anyone can claim this is a scriptural teaching is beyond me.
The next chapter is a complete revisionist history of what CTR was teaching pre 1914.
10. How did the Watch Tower point to 1914 as a marked year?
10 As its full title suggested, the journal Zion’s Watch Tower and Herald of Christ’s Presence was deeply concerned with prophecies pertaining to Christ’s presence. The faithful anointed writers who contributed to that journal saw that Daniel’s prophecy regarding the “seven times” had a bearing on the timing of the fulfillment of God’s purposes regarding the Messianic Kingdom. As early as the 1870’s, they pointed to 1914 as the year when those seven times would end. (Dan. 4:25; Luke 21:24) Although our brothers of that era did not yet grasp the full significance of that marked year, they proclaimed what they knew far and wide, with long-lasting effects.
Of course nothing is said about the fact they were preaching that JC's presence was rocking on right then from 1874/75. They sure as hell were sure about what they thought they knew back then. No ambiguity.
Just like then, so to GB claim all sorts of special knowledge yet are repeatedly exposed as charlatans unable to get one single thing right. If WW1 had happened a couple of years later then I am sure the whole thing would have collapsed years ago.
