It becomes a bit ironic when you think about entire the core foundation of the JWS religion is based upon false prophecy and apostasy according to scripture.
How and why did these self described chosen anointed ones (men) do that ?
Maybe they weren't the chosen anointed ones after all but spirit directed men by Satan the great liar and deceiver, who instigated these men away from true righteousness toward Jehovah ???
They placed the power, vindication and glory of god upon themselves for themselves.
