Revelation is a vision that John received while imprisoned on the Isle of Patmos by the Roman Emperor Domitian. Chapters 1-3, addresses seven churches in Western Turkey, but could have been written to all the churches, especially those of the latter-days. In symbolic language, it addresses the spiritual state of the members, which offering promised blessings to those who repent. Chapter 12, addresses our pre-mortal existence and the war that began there. This war continues on earth between the wicked, directed by Satan, and the righteous, whose allegiance is to Jesus Christ.
