Hi sir82,
It seems to me that the light is fading for the jws.
The changes they made re blood doctrine, generation etc are so nonsensical now that even the most knowledgable jws aren't sure what the teachings are. The generation doctrine was set in stone up to 1995, for example - those who could remember 1914 would still be alive when the new system came. Now the teaching is completely ambiguous, with no definite time period when these things may come to pass.
I imagine that any further changes they are forced to make as time runs out on their predictions will be similarly meaningless.
