I don’t know as I don’t consider myself an expert biblical commentator. That is why I asked the question as this site does have some folks that really KNOW the bible.
It implies a book that is easy to accept as “sweet” but not so easy to digest, nor is the message really simple good news as is first assumed. It could be argued, I suppose, that that “little book” is the New Testament” of the bible.
Not saying I believe that, but when it comes to the book of Revelation, there is a LOT of symbolism and even experts can strongly disagree on the meaning of verses.
