The Bible study - The book of Revelation 
The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified [it] by his angel unto his servant John: 2 Who bare record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw. 3 Blessed [is] he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time [is] at hand.  Revelation 1:1-3
