What is the Book of Revelations?
It’s called the Book of Revelation (singular, not plural). It is all just one big revelation, written down by John the Apostle. The first 3 chapters are addressed to each of 7 real churches that existed in the first century, but after that it transitions into what must take place after these things (Rev. 4:1). At that point the language gets pretty surreal, so there are probably as many interpretations as there are Christians. Nevertheless, it is important that we try to understand because it describes a time that eventually leads up to the Final Resurrection.
