The Book of Revelations

1. The Revelation of John, a servant of God, which was given unto him of Jesus Christ, to show unto his servants things which must shortly come to pass, that he sent and signified by his angel unto his servant John,
2. Who bore record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw.
3. Blessed are they who read, and they who hear and understand the words of this prophecy, and keep those things which are written therein, for the time of the coming of the Lord draweth nigh.

— JST, Revelation 1:1–3

The Book of Revelation is the final book in the New Testament, and Christian Bible. As the only apocalyptic book in the New Testament, the Book of Revelation occupies a central place in Christian theology. With the eruption of the Yellowstone mega-volcano and the destruction of Sol's pre-eminent role in human society, many Christians wondered if the end of days had finally arrived. This belief was eventually abandoned, as several important prophecies in Revelations had not happened.
In particular:

• No asteroid crashed into Earth's oceans and turned them into blood or bloodlike liquid.
• No asteroid had ravaged another third of Earth's water supply, a reference the prophesied star (commonly considered an asteroid) named Wormwood.
• The Earth was not consumed in fire, instead becoming covered in ash that triggered a global ice age.

Although popular Christian belief has disregarded the Yellowstone eruption as the fulfillment of Revelations, it begs a question.  If that was not the apolalypse, how much worse would the real one be?

“I make this broad declaration, that whenever God gives a vision of an image, or beast, or figure of any kind, He always holds Himself responsible to give a revelation or interpretation of the meaning thereof, otherwise we are not responsible or accountable for our belief in it. Don’t be afraid of being damned for not knowing the meaning of a vision or figure, if God has not given a revelation or interpretation of the subject.”
