The very last book in the Bible, being the twenty-seventh in the New Testament, and the sixty-sixth in the Bible as a whole, is The Revelation. It was written by the apostle John, towards the end of his life in approximately 95 AD. John had been exiled to the island of Patmos by the Roman authorities, probably for spreading the Christian prophecies, which was an offence at the time.
Whilst he was banished on Patmos, John received from God a series of visions which revealed to him the future that is to come. John's visions show Jesus Christ as the divine shepherd of the Church, the righteous judge of mankind and the victorious king who will reign from His eternal kingdom on Earth.
"And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them. And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever."
Brimstone, or "burn stone," is an alternative name for sulphur
