I will advise you to quote God's word, word for word. Let it be known that you are writing pieces in your short story that are from Revelation.

Deuteronomy 12:32
What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it.

Revelation 22:18
For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:

So there shall be a penality if you do change/add/take away from His word.
