Very observant observador,
I am regularly frustrated at the WTS's failing to account for failed prophesies, expectations or "light".
There are many more things they have claimed that have not come to pass than is currently published on the internet or elsewhere.
When I was a witness we used to look for the latest WT comment on a subject or scripture to have the current belief.
Yet often their last comment was obviously wrong and they have never corrected it.
The more you look the more you find. Often these false beliefs were the basis for a current belief. So if the basis was false is the current belief still valid?
I belief the WTS can no longer provide a consistent harmonious explanation of their doctrine without creating serious questions and exposing doctrine destroying flaws.
That I believe is why they no loger try.
