My son was "warned" at his place of employment that the end was nigh. I've lived long enough to see this kind of thing come around and around every few years. In fact, when I was very young, the film "A Thief in the Night" (about the rapture) scared the dickens out of me, so much so that I questioned my salvation and rightness with God for quite a while. As PaulS pointed out, even Jesus taught that he would return in his generation to establish the kingdom of God on earth. So far, he is still a "no show". Personally, I have no need or use for fear-based religion and, perhaps like you, Joseph, I would simply wait for the steam to run out. To me, there is no sense in arguing with those caught up in end-of-the-world scenarios or fear-based faith. Fear is seldom rational.
To me, if/when the end does come, it will be due to our own short-sightedness as human beings or due to the natural course of nature (our sun becoming a red giant). I no longer fear or expect God's intervention.
