Revelation 22:v.10-12
10 And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand.
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.
14 Without (of GOD's Kingdom) are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
