Come, Lord Jesus The last book of the New Testament and the Bible is the book of Revelation. Revelations was written by the apostle John towards the end of his life. At the time of his writing this book, John was exiled on the island of Patmos because of his faith. John wrote this book around 95 A.D. The book of Revelation is about a vision John had while he was exiled on Patmos. He wrote to the seven churches in Asia as well as all of the followers of Jesus Christ. The main theme of Revelation is that knowing what is to come should give us peace about our present, no matter how troubling it may seem. John saw terrible visions of the future. These visions included plagues, natural disasters, wars, and an evil ruler. Although
