Apocalypse can generically refer to any prediction or prophecy about the future destruction of the world, that is, the end times. In a general sense, an apocalypse can refer to any prophecy or revelation.
The Bible doesn’t, however, use the word Apocalypse. But you can read about it in parts of Daniel and Revelation, such as:
“The first angel sounded his trumpet, and there came hail and fire mixed with blood, and it was hurled down on the earth. A third of the earth was burned up, a third of the trees were burned up, and all the green grass was burned up” (Revelation 8:7, NIV).
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 1,000-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
