When one reflects back to how the JWS religion evolved from C T Russell's literature reading club to today's JWS who are highly controlled and oppressed, its an interesting study of human sociological behavior.
Once its accepted that the organizational leaders took on the overall role playing as been chosen by god through his holy spirit, specific doctrines were created which further defined the JWS faith to a greater detail extent.
Eventually the JWS took on an internal moniker as being " The Truth "
The usage of " Are they in the Truth ? " could be heard quite often by practicing JWS.
In reality though those specific doctrines were weakly devised with little Scripture support, but nevertheless they created an overall accepting delusion that keeps the religion held together.
