Revelation 22:12-17 KJV
And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.  I am Alpha and Omega, the beginning and the end, the first and the last.  Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.  I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.
