Who wrote the Book of Revelation?

John the disciple of Jesus wrote the book of Revelation. Interestingly though Revelation was written before the gospel of St.John and the epistles of 1,2,3 John, even though it's the last book of the Bible. All were written on the Isle of Patmos where John was exiled for standing up for God. Imagine his persecutors thought to rid the world of his influence by banishing him to that remote island but God worked it out because he was no longer persecuted and was therefore able to reach so much more people through his writings than he probably would have reached had he not been exiled. As Romans 8:31 says "If God be for us, Who can be against us?"
