I confess that I sometimes read the end of a book before I read the beginning. Doing so allows me to know which characters live and which characters don't. When I know how it will turn out, I'm able to relax and thoroughly appreciate and enjoy the story and the characters. In  similar way, reading the final book of the Bible, the book of Revelation, can be and encouragement and comfort for the followers of Jesus. Time and again, Christians are called to be overcomers now and will be for all eternity.
