What prompted this thread was a JW acquaintance wanting help with a generator transfer switch, which (IMO) is pretty far beyond a basic bug out bag. This gentleman served in the air force before his JW days, so maybe that makes him an exception.
On the whole though, I think it's a far more responsible thing to encourage church members to take care of basic needs themselves (Like Joseph during the 7 years of famine) as opposed to the idea that they don't need to lift a finger because God will take care of them personally. Certainly God could do that if he chose to, but no human can know that before the fact and it's irresponsible to tell people otherwise,
