The Apocalypse -- the end of Humanity or of Life As We Know It -- will be at our own hands. Time and time again, false prophets have predicted the End Times, and each time they are wrong. We had one high-profile scam artist predicting the end of the world twice this year alone! Harold Camping, who is now 0-3, seems to have vanished from public life, taking all the money donated by believers with him. There is no way of knowing what will end us -- nuclear weapons, asteroids, swine flu -- but it will not, in my lifetime, be at the behest of any spiritual or supernatural means.
(I reserve the right to be wrong about this, but since the world will be ending, no one will really care. :D )
I do believe in the Bible and in the apocalypse, but I don't believe the words of the Bible can be taken literally. One day, there will be an apocalypse in one way or another. Some believe this will happen exactly as it is outlined in the Bible. Others believe it will happen but the Bible is just a metaphor. Science can prove that eventually our planet will end. At some very distance point in the future, the sun will become a red giant and it will grow large enough to engulf our planet. Eventually, it will go nova and that could be the end of our entire solar system. Of course, many believe we will be living on another planet by then. Others think we will have died out because of nuclear winter or other cataclysmic events. Personally, I think the world as we know it will end one day, but I don't buy into the doomsday predictions. Besides, the Bible says that no one knows the day or hour. If you believe that, then you have to believe that anyone predicting the end of the world is wrong.
Personally, I don't believe in it. The world has always been terrible and in fact has been much worse at times in the past than it is now. I believe that the apocalyptic books of the Bible are not meant as literal predictions of what is going to happen.
I think people have always made predictions about the apololypse, and will continue to do so until the end of time (no pun intended). People are enthralled by end-of-days predictions; depending on what the predictions are and who is making them, people tend to get drawn in. What we fail to realize many times is that different individuals and groups have made so many predictions in the past and have been, obviously, wrong. It is easy to say that our world is headed for destruction because of war, famine, natural disasters, etc. However, if you look back in history, our world has been in turmoil for billions of years; it just seems worse when we are the ones living it.
So, while I do enjoy reading about theories, and especially reading fictional literature that depicts post-apololyptic worlds, I don't much buy into the hype. I think we should continue to be good people, not because we anticipate judgement day, but because that is the right thing to do.
