The book of Revelation has always fascinated Christians. Its cryptic messages and vague warnings have had people debating over its meaning since it was first written. That has not changed in the modern era. Blogs, books and truly uncountable sermons have been written on the topic. No one, however, has yet managed to put a hard and fast date on the end of the world. The signs may give hints when it is coming, but the Bible itself says that no one will really know the end is nigh until everything comes crashing down.
