Is what Revelation does not say as important as what it does say?
Yes, realizing what the Book of Revelation does not say is just as important as seeing what it does say. Many people assume it says things it does not, so careful attention to both its explicit statements and its silence is essential.
Les teaches that this is a point he has made over the years: it is just as important to realize what the Book of Revelation does not say as it is to see what it does say. He notes that a lot of people think Revelation says something, when it actually does not. This caution comes as he is winding up his study of Revelation, returning to the last chapter.
