Flipper - when the question is asked as to whether one is comfortable about not knowing the future after leaving the JW's religion, the presupposition is that the JW religion did know the future, or at least the members believed in such.
The reality is the JW's do not, nor have ever known the future. It is a belief system of the future, handed down by Bethel that all members become impregnanted with, that they come to accept.
When the belief system is proven faulty, so then is the said future that was falsely prophecied.
All JW's and all ex JW's do not know the future. The difference is the former are led to believe they know, but in reality they do not; the latter understand they don't and won't let others tell them they don't.
It's a matter of perspective, but both parties don't know anything.
I'm happy knowing my future in general. The details of my future are not important and I'm okay with that.
Peace
Maksym
