When you hear the words “The end is near!” what comes to mind? Do you think of a wild-eyed preacher thundering from the pulpit and gesturing dramatically, Bible in hand? Or do you picture a bearded old man standing on a street corner, wearing a long robe tied at the waist with a rope, holding a sign bearing a doomsday message? Imagining such scenes may make some people feel concerned, while others may feel skeptical or even amused.
