For more than 100 years the Watchtower played with the date 1914. Some fairy tale interpetation about the lenght of certain pyramid passage way in egypt and a babylonian king regaining his sanity, not to mention a whole lot of sencondary fulfillment and a tremendous amount of gulibility and fugded figures for the ancient history dates of supoosed events.
Basically it is the wild imagination of the writers and leaders of the Watchtower Printing Corporation and it is used to sell more books that proclaim to unlock the mysteries of the Bible and then use them as a sales pitch to get free workers to sell their printed product, a money making enterprise being passed off as religon to avoid taxation and alimony payments to Russel's wife and one time co editor.
Russel took a fancy to being reverved for his role as top CEO of his own company, and begrugingly excepted the title trust apon him by his indoctrinated readers, who following his cues, appointed him to the office of Faithful Servant mention in the parable about such a servant.
This seemed to work out good for the Corporation but latter when its founder died, it caused problems for a book selling lawyer, Rutherford, who managed to seaze power and kick to the curb any not following his lead all opposition was squashed and he then ruled supreme over the Corporation. Later he went on to meet the lord in the air and rule with his noble faithful servant of the lord. Still no proof for this kingdom's existance except some Corporation's claims that it was in operation since 1914.
But thru it all the hope and imaginary kingdom they have built up in the minds of their free labor drones has be able to do absolutely nothing, but strangely thru the power of the treat of disciplinary action the Watchtower Corporation has been able to keep the rank and file working for this imaginary never done anything Kingdom of God, even till they die they hold on to this pipe dream. No one is allowed to think differently as "independent thinking" carries the maximum penalty of disfellowshipping and loosing one's everlasting life for the thought crime of harboring doubt about the Organization's Imaginary Kingdom of God, elders are to keep a close watch over the Corporation's free labor source and swiftly handle any violaters.
The Imaginary Kingdom of God now in official operation since 1914, is really a thought prison to keep the cash flow positive for the the Watchtower Corporation so that they can do buisness with their Mina until the lord's arrival and not bury it in the ground, or aleast get some interest on it.
