Book of Revelation
The Book of the Revelation of John is the last book in the Bible. It was written by John of Patmos, traditionally thought to be John the Evangelist in exile on the island of Patmos, Greece. It describes the apocalypse.
Revelation is famous for being full of symbolism, most of which is incredibly vague. The European Union, for example, could legitimately be described as a sign of the end times, as could FIFA, global warming or literally any election.
