Revelation is the last book of the New Testament. In the English version it is called The Revelation of Saint John the Divine. It is also known as the Apocalypse of John. The Apostle John was supposed to have written it while he was in exile on the island of Patmos. Some scholars think, however, that it may have been written about A.D. 95 by some other man who used John's name. The material in the book comes from Christian, Jewish, and Babylonian sources. But the original text of the book was in Greek.
The first part of the Book of Revelation contains a message to the churches. The second part contains a series of visions of the future. The book was probably intended as encouragement to the persecuted Christians of western Asia Minor. They had refused to worship the emperor and were in great peril. The book was intended to show that Christ and His followers would soon be victorious over their enemies.
