And what does fear bring about?
The fear makes it difficult to enjoy one's life because so many events become tied into the feeling of pending doom all "foretold" in Revelation, Daniel, and Jesus' Olivet discourse (and other places in the Bible). When there is a chip available to put into one's pet in case it gets lost, that becomes the Mark of the Beast which will eventually be required for all people. When dolphins die in large numbers somewhere in the world, that becomes the blasting of one of the trumpets in Revelation. When there is a succession of earthquakes, those are signs of the end-times. When there is some ecumenical movement among various religious leaders, that becomes the first steps toward a super religion which will be headed by Satan's minions. When nations sign various treaties to try to work together, that becomes the one world government over which the anti-Christ will rule and bring his "foretold" doom upon the world.
For some, it becomes difficult to enjoy one's life because any year, month, week, or day the anti-Christ will make his appearance. Some will be raptured away, but some will be "left behind" to endure what they think will be the worst struggle in human history where one wrong move will land one in hell for eternity. The fear is that the individual going through all of this doesn't have what it takes to be raptured away and so must endure something worse than has ever happened in human history.
It's not that I can assure anyone that bad things won't happen because they will. There will continue to be crimes, war, famines, earthquakes, hurricanes, dolphins dying, etc. But maybe if people will come to realize that none of it is tied in any way to the alleged prophecies of the Bible, they will at least be able to put the fear that it is being orchestrated at the divine level out of their minds. They may not feel so helpless, either, at least for the issues which we can control (i.e., war and famines caused by political intrigue, etc.) and people will realize that something can actually be done about those things.
