Revelation 22:11-14 (KJV)
11 He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
12 And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.
13 I am Alpha and Omega, the beginning and the end, the first and the last.
14 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.
