I can only guess your thoughts. Takes me back to late seventies madness in the Worldwide Church of God when I was but a mere lass. More recently the Y2K crapola.
The sky is always falling. Gee, did anyone ever think to pray when times get tough, as opposed to storing giant amounts of food and water and scaring kids to death?
We're doomed. Doomed I tell you. We're all going to die! (eventually)
I can see the wisdom in storing food. But I see more wisdom in trusting God.
