For the majority of us, certainly here in the UK, it's not a "Go Bag" that we need but a "Stay Bag". Not a literal bag of course but provisions set aside for an unexpected event. This event is not necessarily a major calamity such as we are currently facing but just a bad winter with snow such that we don't want to go out shopping, unexpected sickness or whatever.
In the US they are called "preppers" and attract scorn and derision but preparing for future events is a very sensible thing to do. I cannot understand so many in my congregation have so little to no provisions set aside. I think they work on the "Jehovah will provide" idea. Well he hasn't and he won't.
