And 1,335 days is just about 3-1/2 years, which is half of seven years, which is another one of those symbolic numbers. I suppose you can take all the numbers literally, but certain numbers in the Bible are used so often, that it would seem that they must have a symbolic, rather than a literal significance.
Apocalyptic literature like Daniel and Revelation is full of symbolic language, and it seems to me that such language is intended to convey a mystical experience of the divine, rather than a literal description of something. To be tied to the so-called "literal" interpretation, often seems to miss the true meaning of what is expressed.
And then comes the question of what exactly are these apocalyptic writings talking about - are they talking about the end of the world, or about some cataclysm more immediate to the times when they were written? The Book of Revelation was written to the churches in seven Greek-Roman cities in Asia Minor that were facing persecution from the Roman Empire. I think Revelation was written primarily to give hope during that persecution, but that it has other layers of meaning that apply to our times, and the times to come.
I've been studying the Book of Revelation lately, and I've found it very interesting. It reads like a fascinating fantasy novel, but a novel that teaches profound lessons about the struggle between good and evil.
But as for numbers being specific and literal, I don't buy it. It's very clear that apocalyptic writings are rich in symbolism - and it's not likely that we'll be able to understand a lot of that symbolism, any more than we can fully understand the symbolism used in poetry and other writing. And I can't buy the contention that the heads and crowns of the beast apply to current political entities. Why should they apply specifically to now, and not to the times in which they were written?
Those who claim to interpret apocalyptic literature "literally," do a whole lot of speculation. Speculation about symbolism is fine - as long as you can admit that you really don't know the answer. I think this kind of writing is meant to challenge our imagination, to make us dream bigger dreams and ask bigger questions.
