My question is about Deuteronomy 4:2, and the command not to add to or subtract from the Word of God. How do we know that this doesn’t apply to the books after Deuteronomy? Is there anything in the book of Deuteronomy or the previous books to support this?
Deut. 4:2 contains instruction from Moses on what he was about to tell them. Same with Deut. 12:32, where Moses repeated it. But Prov. 30:6, Galatians 3:15, and Rev. 22:18-19 say essentially the same thing about other parts of the Bible. And Proverbs 30:5 says that every word of God is flawless and we should not add to any of it. It looks pretty clear that we’re to accept His word just as it is.
