It is not uncommon for theists to project their fears onto their own eschatological dogma or, in other words, to allow their emotions to interpret their end-of-the-world doctrine as having a fulfillment that must be imminent.
Many Christians have felt as you do. But it is important that we do not let our emotions or personal feelings regarding world events to shape doctrine and its interpretation. Because many have not be so cautious, thousands even millions of Christians have made unnecessary and radical changes to their lives believing that the world’s end was near. Most fell prey to charismatic leaders that promised more than they could deliver, left family, job, homes, and even self in order to be prepared for a soon-to-occur Armageddon that never materialized. Many of these put their faith in dates such as 1874, 1914, 1945, 1975, 1977, only to be discouraged when the dates came and went. It is vital that we not do such things anymore.
One of the problems is that many Fundamentalist Christians view the Bible book of Revelation as some sort of fortune-telling book, believing that its imagery and symbolism are coded prophecy of soon-to-occur events, like it were some sort of crystal ball. It isn’t. Revelation is a book in the style of an ancient genre wherein an oppressed people used symbols to encourage one another to endure until justice won out on their behalf. It wasn’t written to actually foretell in detail what the future would be like.
However, the end will come in someone’s lifetime. Perhaps it could be ours, but then again it may not. We should be prepared either way, for our own life can end at any moment and our judgment will not wait for an apocalyptic disaster to strike the earth.
