First off, let me say I respect David Wilkerson as a true minister of the Gospel. He is the Pastor and Founder of the great Times Square Church in New York City. He is the renowned author of the Cross and the Switchblade. He is a great Preacher! He recently released at statement about an impending catastrophe that will hit the Greater New York City area and subsequently affect the world!

Now let’s look at the prophecy! I think we, as mature believers in Christ, are given some answers in the bible as to how we should respond.
In I Thessalonians 5:20-21 it says
.. do not treat prophecies with contempt. Test everything. Hold on to the good. (NIV)
And my personal favorite, Acts 17:11
Now the Bereans were of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true. (NIV).
We have the God’s Word, and instructions from the apostle Paul as to how to handle prophecies and the words we hear from preachers. We are to test them to see if they line up with the written Word, which God has provided to us through the bible. 2 Timothy 2;15 says “Do your best to present yourself to God as one approved, a workman who does not need to be ashamed and who correctly handles the word of truth.”
Now we do know that God’s wrath is revealed against all unrighteousness and against those who hate God in word and deed. So we want to look at the scriptures Pastor Wilkerson has given us and make sure how they are used is in the right context. (Psalms 11, Jeremiah 18). Then we want to look at the other things he said and determine if they correctly flow from his use of the verses (i.e. buying 30 days worth of groceries, etc). I will look into the scripture myself so if anyone is interested in my findings please email me and I will share them with you.
Psalms 11
This Psalms is a song of trust in the Lord. It is describing David’s trust in the Lord despite the flexing on the enemies muscle. Psalms 11:3 When the foundations are being destroyed, what can the righteous do?” where “foundations” mean the established law and order in a civil sense. Verses 4-7 are David’s response to the option to flee presented to him in verses 1-3. He is saying he trusts in the Lord, the God of heaven, to justly deal with his enemies, who because of their deeds are enemies of God as well.
Jeremiah 18
This chapter is a prophecy from the Lord to Jeremiah concerning His people Israel. The first few verses pertain to God as the potter, with the ability to mold and make as he pleases. Verse 7 and 8 say “ If at any time I announce that a nation or kingdom is to be uprooted, torn down and destroyed, and if that nation I warned repents of its evil, then I will relent and not inflict on it the disaster I had planned.” This, once again is in regards to the Jews, who were still under the law and the Old Testament. It is God explaining His mercy to His people if they turn and repent. Verse 11 is God proclaiming His right to execute judgment on His people if they do not turn. So in my opinion, this is God speaking to His people, not a reference to heathen countries (the United States? New York?)
With Pastor Wilkerson’s prophecy, and preceding statements, I very much wish that the message of the Gospel was there so as to give people a message of hope within the midst of the disaster.
In the aftermath of 9/11, Katrina and other disasters, I think it is always prudent for us, as the people of God, to have a watchful eye, be prayerful and be prepared to the best of our ability. I think it is a good idea for all of us to have extra food, some extra resources at our immediate disposal so as to not only help ourselves, but to help a neighbor or friend.
My only other concern was with the last statement, and I will quote it here “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.” Perhaps I am taking wrong but it almost sounds like he is saying “I did my job and told you, now you do whatever you want with the info” What I would hope that might happen, is that he meet with some other respected Christian leaders and pray with them about it. We know that Proverbs says that “In a multitude of counselors there is safety” (Proverbs 11:14 and 15:22). At the very least, a call to believers to watch and pray and to be encouraged in the Lord because He loves His people. I am concerned that people will do things out of fear, without thinking and praying.
So concluding I just want to say that it could be true so let us not despise his words but let us also, as believers “test all things” and pray that God would lead us in whatever way He sees fit.
