Apocalyptic Warnings

On Saturday, March 7, David Wilkerson, he of The Cross and The Switchblade fame from the 1960's, sent out a warning to all of the people who were part of his blogosphere contacts. I have copied the first part of his blog below:

AN URGENT MESSAGE
I am compelled by the Holy Spirit to send out an urgent message to all on our mailing list, and to friends and to bishops we have met all over the world.

AN EARTH-SHATTERING CALAMITY IS ABOUT TO HAPPEN. IT IS GOING TO BE SO FRIGHTENING, WE ARE ALL GOING TO TREMBLE - EVEN THE GODLIEST AMONG US.

For ten years I have been warning about a thousand fires coming to New York City. It will engulf the whole megaplex, including areas of New Jersey and Connecticut. Major cities all across America will experience riots and blazing fires—such as we saw in Watts, Los Angeles, years ago.

There will be riots and fires in cities worldwide. There will be looting—including Times Square, New York City. What we are experiencing now is not a recession, not even a depression. We are under God’s wrath. In Psalm 11 it is written,

“If the foundations are destroyed, what can the righteous do?” (v. 3).

God is judging the raging sins of America and the nations. He is destroying the secular foundations.

Wilkerson closes his blog with these words:
Note: I do not know when these things will come to pass, but I know it is not far off. I have unburdened my soul to you. Do with the message as you choose.

Needless to say, this has created quite a firestorm among the religious blogging community. There has been enough controversy that, a week later, on Friday, Mar 13, Gary Wilkerson defended David's choice to share his message of impending doom in this way:
It is the task of a true prophet to warn. We have recently heard such a clear warning of perilous days just ahead of us. The prophet is like a man who comes to warn a shepherd that ravenous wolves are approaching.

How do you react to such things? Do you give the message enough credibility that you would look to leave the Northeast, just in case? Does a message like this from a minister like this have more truth than the messages of impending doom from Nostradamus recounted in the supermarket tabloids? If you are a part of a church, how would you respond if someone asks you, "What do you think about this?"
