<p>22:18 <em>I testify to every man that hears the words of the prophecy of this book, that if anyone shall add to them, God shall add to him the plagues which are written in this book</em>- The reference is not to the whole Bible, it is specifically to the words of the prophecy of the Apocalypse. The only other time the Greek text talks about 'adding things' is in Acts 15:28 where we read of the tendency to add things to salvation by faith alone. I have suggested that the language of the New Jerusalem and the open temple is all to be understood in the first century context in which it was given. For the admission of non-Jews to a largely Jewish Christian community was a live issue. The picture presented here is of an eternal salvation where literal Jerusalem and its temple are surpassed by the reality of the Kingdom, and the 12 tribes of Israel are no longer to be understood literally. So I suggest with that background, the idea here is that the great salvation just presented is available to all, freely. And anyone who adds conditions to that shall be excluded from it; and likewise any who detract from the vision by not believing it. For the fearful and unbelieving are listed in Revelation alongside the whores and sorcerers who shall remain outside the new Jerusalem.</p><p>Yet the plagues written in the book have specific reference to latter judgments upon the Jews and upon the supporters of the beast in the earth / land promised to Abraham during the three and a half year final tribulation. Islam adds to the prophecies through claiming that the Koran and Hadith were given after the time of Revelation; and first century Judaism added to God's book by elevating their laws and traditions to effectively the same status as the words of God un the Bible.</p>
