christians often discuss topics from the book of revelation, including the millennium, a 1000-year period when christ will rule the earth. revelation also describes a final war between good and evil known as the battle of armageddon, though the word "armageddon" is also sometimes used to describe any large war that ends the world. both of these events are thought to be literal by some and figurative by others. while virtually all christians agree that there will be a second coming of christ, it is the subject of conflicting accounts in revelation and therefore much disagreement about its details.
