Dave Wilkerson has had a vision of New York City burning. He is advising the stockpiling of food and water. In general, I find most modern-day "prophets" unreliable. I used to watch Hal Lindsey's TV show, until I started totaling up his predictions and realizing how many hadn't come true. I also like Perry Stone, and think he can speak the truth more often than not. Even so, he has a tendency to go towards the deep end of "connecting the dots".
David Reagan is one end-times ministry leader I like. He doesn't make predictions or set dates. He just preaches God's word. However, on Lamb and Lion Ministry's blog, he is supporting Wilkerson a second time. Since I believe that David Reagan is a Spirit-filled man, I took a second look at Wilkerson's message and some of his others.
I'm not sure about his message. I do know it's easy to test: it will either happen in the next couple of years, or it won't. I do think his suggestions are wise: storing up supplies are essential, just given this economy. Any significant jolt could disrupt our current "just in time" supply chain (like the Atlanta-area gas shortages).
Fortunately, I'm not headed anywhere near the Megalopolis until next year at the earliest, so I don't have to put this theory to the test.
