If there is something like a nuclear, biological or chemical attack in one area then survivors are to head to nearest safe area. Or any other situation where you have to leave your area. The congregations in surrounding areas will be asked to house displaced JWs.
It will be a voluntary thing but those who say no I can’t have anyone in my home will stand out compared to those who volunteer to have people sleeping on the floor.
The point is everyone should help each other related in the faith. And when there is a disaster that displaces lots of people there needs to be good organisation.
GB update number 3 showed some areas affected by draught and other area’s flooding. Humans are ruining the earth and there will be more of this going forward. Disaster relief committees need to be well organised to help in the best ways.
Also the way the West is pushing Russia and China and the banking system near to collapse, there is more of a need to have go bags and a bug out plan than ever before.
Brics currency could replace the dollar and when currencies collapse there could be chaos. I think you are much better off being part of a well organised community than being a lone wolf.
