You cannot properly understand End of the Age prophecy unless you properly understand the Book of Daniel. The Book of Revelation tightly ties into the Book of Daniel, and Jesus validated the entire Book of Daniel in Matthew 24:15 The main difference between the Book of Daniel and the Book of Revelation is that the Apostle John more fully develops the themes of Daniel, i.e., the risen, glorified, resurrected and triumphant Jesus.

Rev 12:1-11 presents a picture of war even in Heaven itself, comparable with Daniel 12:1-4.

You cannot understand the events of this current age unless you thoroughly comprehend this battle in the heavenlies
