Revelation 22:11,12 (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.
The Bible Is God’s Word
Because people cannot always be trusted, do not let them tell you that God’s Word is also found outside the Bible, in other books.
