Sorry, I should have added this to my earlier post.
The pastor who is advising people have a month's worth of food and essentials on hand is David Wilkerson. HERE is the link to his general blog (it's short enough that I can type it in for the link). Just scroll down a bit for the post about stocking up called something like An Urgent Warning.
I've received Wilkerson's snail mail newsletters for over twenty years now. Some my age may remember the movie about his early ministry in New York called The Cross and the Switchblade (starring Pat Boone). He is the senior pastor at Times Square Church.
I'll let you use your own discernment regarding what he has written. I know it may not be in agreement with some people's theology but I do know a lot of people who respect him.
I've been watching Glen Beck who is now on Fox News when I get a chance (he now comes on at a time I am often busy). It's amazing to me how many people he has interviewed who are recommending storing food, starting a garden, etc.
I remember one episode when he was still on CNN, it was the first time I'd ever heard of an economist recommending investing in "canned goods". Hmmmm...
Beck has also talked about the possibility of riots in the cities.
