Revelation is the understanding of things which GOD gave to Jesus, after He was crucified and resurrected to heaven as a spirit being, and because the believers were in agony by the Romans, and things of the wrath would start to happen real soon (35 A. D.), GOD sent an angel with a letter to give John, so he could know why things are, and how they got that way, and HE wanted those who read, or heard this prophecy, and take time to obey the words to know they are blessed, because they would know what to do, and that the time to do those things was near.
