This has been offered to the reader as if to say that from the very outset, any study of Revelation that is done or offered without the direct application of Jesus' teaching, specifically His sermon on the Mount of Olives, is incomplete at best. The argument that God conclusively broadened His redemptive purpose beginning with the Jewish people then spread to all races, as promised in Matthew 28:19, rings true in Revelation when understood in the context of what Jesus taught. What's more, the development of temple-based worship into a simpler spiritual-based worship as expected in John 4:21-24 is equally difficult to ignore from what appears to have been fulfilled in the prophecy of Revelation as predicted by Jesus in His Mount of Olives sermon.
