Revelation 22:18-19 I testify to everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues which are written in this book; and if anyone takes away from the words of the book of this prophecy, God will take away his part from the tree of life and from the holy city, which are written in this book. Deuteronomy 4:2 You shall not add to the word which I am commanding you, nor take away from it, that you may keep the commandments of the Lord your God which I command you. Proverbs 30:6 Do not add to His words Or He will reprove you, and you will be proved a liar. It’s rather clear that the Book of Mormon is an abomination.
