what is Apocalypse?

The word “apocalypse” comes from the Greek word apocalupsis which means “revealing, disclosure, to take off the cover.” The book of Revelation is sometimes referred to as the “Apocalypse of John” because it is God’s revealing of the end times to the apostle John. Further, the Greek word for “apocalypse” is the very first word in the Greek text of the book of Revelation. The phrase “apocalyptic literature” is used to describe the use of symbols, images, and numbers to depict future events. Outside of Revelation, examples of apocalyptic literature in the Bible are Daniel chapters 7–12, Isaiah chapters 24–27, Ezekiel chapters 37–41, and Zechariah chapters 9–12.
