FootnoteThe book of Revelation was written by the apostle John, the same one who wrote the gospel of John and the three epistles or letters of John. It was addressed to a group of seven churches in Asia Minor (now modern Turkey). The first three chapters deal with admonitions from Jesus to those churches, and then, from chapter 4, where John is caught up into heaven, and onwards to the end of the book, the apostle is shown events yet future.
