OMG.....The scary thing about your post is:<quoted text>
Let me ease your worry brother....
The end of the world will not come until the 7 years of tribulation occurs during which the Anti-Christ will reign. The start of that reign will come after the rapture.
So - you don't have to worry about the end of the world until millions just one day disappear - born again followers risen up to meet Christ as he comes back to Earth to claim His Kingdom.
Here's a thought - if you are a professing Christian, but not following His teachings and haven't accepted Christ as your Savior, and you know about the rapture, and are still on earth after it occurs - then you will know that you have 7 years before the World Ends as we know it. And you know that the only way to survive and go to heaven is to accept Him then and now.
Yet - those left behind, and the Anti Christ will make being a Christian extremely difficult, extremely dangerous.
But even then - the World will not truly end - it will be made whole and God's Kingdom will reign for a thousand years.
For once I actually agree with something you posted, probably the first and the last time....LOL
