In the Bible it says, “And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.” Revelation 22:19 My question is, what exactly constitutes adding to the Bible? Is it permissible for me to mark important passages or write my own notes beside a verse or story I find particularly confusing?
Rev.22:18-19 says,
I warn everyone who hears the words of the prophecy of this book: If anyone adds anything to them, God will add to him the plagues described in this book. And if anyone takes words away from this book of prophecy, God will take away from him his share in the tree of life and in the holy city, which are described in this book.
This is a warning that applies only to the Book of Revelation. It prohibits changing the text of the book by either adding to or taking away anything John has written. Underlining, highlighting, or making marginal notes in your Bible won’t change the text and therefore these actions are not included in the warning.
