Quite the contravening question to contemplate for any self avowed devoted JWS, which no doubt takes some uncomfortable thinking to consider.
Yes back in 1919 the then president of the JWS J. Rutherford proclaimed that the organization (IBSA, JWS) had been selectively chosen by Jesus for their unique preaching and evangelical work.
There had already been a proclamation by the past leader of the (WTS) IBSA C. Russell that he was the faithful slave doing the lords work, will and purpose, but his professing doctrines were also false bible interpretations based upon the theology of Pyramidology.
Might it be that these men made these proclamations out of the intent of self validating themselves and the literature that they had published and were trying to proliferate ?
Making these kind of claims was easy since there was no higher governing body to evaluate these men's endeavors from a theological standing, The American government had opened the door for any individual's self expression of a religious nature. So anyone in that country could build up their own religoius following unimpeded, even more so if that religion was Christian based.
So the real critical question remains how or why would Jesus pick these men when their doctrines were so obviously false and probably devised more so from a commercialization agenda ?
I personally contemplated that question myself before leaving the JWS entirely.
