There is a difference between the leadership of the Borg (GB 2.5, is that what they're on now?) and the Sheeples, that for a variety of reasons, stick with this nonsense.
Not every JW publisher believes this stuff. The GB knows this. But if you play the game right, you can be called "weak" and be able to hang out with family and friends, with minimal fuss.
The motives of the Sheeples class is not what this is about. Simply put, it's about the leadership. I learned this the hard way in 2005, when I studied the bible in depth, and the whole point of it was to "build my faith up" that the bible, and most/all of the major characters in it (Noah, Abraham, Isaac, Jacob, Ishmael, Judah, Joseph, Elijah, Elisha, David, Solomon, someone stop me here...) all "prophetically" pointed to the existence of Russell and the JW's in the 20th and 21st centuries.
So, why do you think there is so much "change" in doctrine? About things like the "generation?" Why do you think there is a lack of acknowledgement about 1914 and the generation that saw it? Why do you think they talk so little about 1914 these days? (Big hint, it is 2018...)
The leadership is all about one thing, keeping power, and keeping their fruity little cult going. The scriptures, as I sadly learned at Gilead, are never about the Sheeples. Amazingly, throughout the history of JW's from Russell on down, the ruling class has used the bible to support their leadership, and because of that, you should follow them. THEY are the chosen channel, not you. THEY have a special relationship with (YHWH/GOD/CHRIST/THE LAMB). Not you.THEY get to partake of the emblems, not you. THEY are anointed by holy spirit, not you. When a prophetic doctrine has to be changed because it simply never came true and never had a chance, THEY get to claim that god's spirit is with them, and YOU were wrong to believe it, and remember, change with us because the holy spirit is with us.
Motives matter. This cult isn't about improving your relationship with god. It's another sad exercise and peek into the human experience, that shows frankly that most people do not have, or do not want to, think critically or think for themselves. In farming off that responsibility, and not questioning reality or what you hold dear, delusion sets in, and you get groups like the Sheeples that live their life, unaware that it has never been lived.
That is why I say, think for yourself, live a life you have dreamed and imagined, and go for it. Choose happiness in life, and don't spend too much time chasing this fruity little cult around. They are truly the wizard behind the curtain, and never mattered at all.
