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.
Revelation 21:1-4
"And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away"
