The last book of the Bible and of the New Testament is the Book of Revelation. In it, John prophesies to humanity what will happen when Jesus comes back to the earth. Some of the most famous features include the four riders of the apocalypse, the last judgment, the battle between angels and devils, and purgatory. Willy Wiedmann ends his work with the words “He who testifies to these things says: Yes, I am coming soon. Amen. Come, LORD Jesus! The grace of the LORD Jesus Christ be with you all! Amen.” Revelation 22:20-21
