Not a bad idea of God's.
Also many scriptures about false prophets and the many that would come in His name.
Imagine without the admonition to not add to the Bible, it would be possible for LDS, Jehovah's Witnesses and Islam to be accepted as valid revelations from God.
I notice that all of the hard questions put to the apologists are not answered.
Just refuting of scriptural passages and references that deny the creations of more Abraham based religions.
Ah, but Joe Smith proclaimed himself the prophet of god so he was authorized to add thousands of words to the King James Bible (he called it ‘a more accurate translation’, LOL), a prophecy of his advent in these latter days (more than 800 w0rds added to Genesis 50), and extensive additions to the Book of Revelations. Even poor ol’ pedophile Mohammed didn’t go that far!
"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: 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."
A brief review of some historical facts should clear up this issue. The Bible is a collection of sacred writings that were compiled into book format centuries after the death of the original writers. When the Apostle John wrote these verses, the Bible as we know it today had not been compiled yet. Therefore, his words could not possibly be applied to the entire collection of writings today known as the Bible. John was referring specifically to the Book of Revelation.
Additionally, even though Revelation is traditionally placed last in the Bible, most Biblical scholars do not believe that it was the last book to be written among the compiled records contained in the Bible. If your reasoning is true, then those Books would also have to be removed from the Bible and discarded as false.
Also, please note the very similar wording by Moses found in Deuteronomy 4:2:
"Ye shall not add unto the word which I command you, neither shall ye diminish [ought] from it, that ye may keep the commandments of the LORD your God which I command you."
If your interpretation of the Revelation verses were correct, then they would have to be applied here as well. In which case, the Old Testament after Deuteronomy and the entire New Testament would have to be discarded as false.
Finally, I should say that the words of both Moses and John are true. Man should not take it upon himself to add to or diminish the word of God.
"For the prophecy came not in old time by the will of man: but holy men of God spake [as they were] moved by the Holy Ghost." (2 Peter 1:21)
God has a plan for us and chooses men called Prophets to teach us his plan. Prophets teach the word of God as they are moved by the Holy Ghost. It is the same today as it was 2000 years ago, for God is the same yesterday, and today, and forever. (Hebrews 13:8)
"For he is the same yesterday, today, and forever; and the way is prepared for all men from the foundation of the world, if it so be that they repent and come unto him". 1 Nephi 10:18
