I have been a JW my whole life and I have never been able to get a clear answer on this question.
Jw's do not believe that Jehovah will intervene if someone is sick, dying or stopping a car crash. They feel that Jehovah is letting "this world" play out before he solves all of these problems. For example, if Brother Faithful has cancer he is not to pray for Jehovah to heal him. Rather, Brother Faithful is to pray for strength to endure his challenge. Seems rather convenient right? Of course he's going to have to endure no matter what until the cancer kills him.
However, on the other hand you have brothers giving experiences at conventions, Kingdom Hall, Assemblies and Year Books about needing X amount of money to continue pioneering and Jehovah gave them exactly the amount they needed by a random donation. How Jehovah must have provided exactly what they needed!
Brother Faithful wants a new chair for his bible study room but can't afford one since he is pioneering. On his drive home from service he sees a great chair that someone is throwing out. How Jehovah must have provided that chair for him!
You guys get the point. So which is it? Jehovah won't provide for someone dying of a sickness or stop a car crash yet he will give Brother Pioneer $20 to make his bills or give him the new chair he didn't really need for his office?
I have yet to get a straight answer on this question. Does anyone have any insight?
