I would have to say YES...they do believe this. After all, to say anything less would be to admit that they have wasted their lives affiliated with an organization that is NOT God's chosen channel. It would be to admit that they are not the elite as Rutherford once called them. They are all in...at least publicly.
I think about how difficult it is when one begins to wake up to the reality of this organization. Where once the explanations were clear and accepted as coming from an "elect" source. Now, one reads between the lines. For most, that only happens when you begin to pull away. It is kind of a surreal experience like floating above a forest to see where the smoke that had blinded your campsite originates. When you can see from afar, the topography of the organization is full of valleys and chasms with no paradise in sight.
It is my belief, that for those at the top, they have set up their tent in the middle of the forest. It is THEIR fires that are burning, so much so, that their own vision is obscured by the smoke they have created.
Just a thought,
