The prophecies in the book of Revelation have been an ongoing thing since God the Father gave them to Jesus who gave them to the angel who gave them to John, who said that these are things "which must shortly come to pass" (Revelation 1:1).

The book of Revelation is a combination history and prophetic trip from the time Jesus ascended to Heaven until our time. There are only a few more events left to happen. We are in the very end of the end times.
