No. I always remember that during the Charismatic outpouring they were convinces that the end of the age was upon us. and they were selling "Revelation food" (dehydrated food) in either 3.5, or 7 year portions, depending on you "eschatology" (Pre, Post, or Mid).
if you were a "Pre", or a "Middie" they strongly suggested that EVERYBODY buy the 7 years supply anyway - in case your "Eschatology" was wrong. However they didn't supply an assault rifle, to use against your starving neighbors when they came for your supplies.
As far as I'm concerned, God's arm isn't shortened, and "Preparing" is really nothing more than a "Marketing effort".
