What George Carlin says about the Government, can also be applied to JW's. The JW organization offers the feeling...the illusion of security and JW's have become neurotic about perfection and so obsessed with security that they are willing to trade away their freedom and often their family members in exchange for the illusion of security.
What we are going through now is a world wide disaster of sorts and all that JW's have to offer is information that they've cut and pasted from government guidelines and empty soothing words but noting in terms of tangible help. Why is this disaster any different than any other disaster she is expecting to face? If they don't have anything to offer now, what will they have to offer If there are worse disasters in store for us?
The JW's that are currently out of work or in trouble financially, physically or mentally because of the pandemic have turned to the worlds governments to get any kind of real time help, just like everyone else has. If your family was in trouble, her JW friends might offer her encouragement over the phone for a few days but they'd have nothing to offer in the way of real help...not for very long anyway.
My wife's Uncle is a long time Elder and his wife has regular Pioneered for decades. (wonderful people with 5 kids) At the time he was a substitute C.O and was also in charge of the finances at the assemblies etc. There was a lot of "tribulation talk" going on back around 9/11when my kids were small. In terms of the "great tribulation" we were all thinking when the towers came down, "this could be it". I was telling him that I was worried about how I was going to feed and protect them during the Tribulation if I were to loose my job. I asked him what he'd do if his business went under because the economy crashes during the tribulation. He said he'd move to where he could find work. I asked him about leaving the all Brothers and Sisters in his congregation behind who need direction and he said "Jehovah doesn't expect me to let my kids starve...I'm not in charge of other people's lives".
This was a real eye opener for me. Up to that point, I had naively believed that the we as JW's would band together during the tribulation and the Elders would be guiding us through whatever happened. Apparently he had a much different idea about it.
If my wife told me that she was going to dump me the minute anything went seriously wrong in the world, instead of rally around me, I'd have to seriously re-evaluate the future of our relationship.
Ask your wife if she were to suddenly to become a lone divorcee right now, how many of her JW friends would include her in social gatherings or put up with her need for emotional support on a long term basis? Ask her what the plan is when the things she has in her "to go" bag have all been used up and there's nothing left in anyone else's to go bags either, who will she turn to if you're not there?
JW's tend to live in a fantasy world when it come to "the tribulation" they don't think of it with any detail. Ask her for specific names of who she will turn to, what they will have to offer her and for how long. Ask her to paint a detailed picture for you and describe where she is, who she's with and where you and your boys are when she's using her "to go bag".
