This passage deals with Jesus revelation to John. The point of Revelation is the reveal to the church the things which must shortly come to pass. Those things are stewarded by John, the apostle who did hard time on Patmos and is transported through time and space to see things which will come to pass. These are the things we need to know before we go and meet the Lord in the air. Time is short so it is important to behold the Lord Jesus Christ as he reveals himself to John and us in the book of Revelation.
