Hi joshua,
Well, I'm not sure that God means to infer that it would actually 'roll' up. It's a simile and the use of simile is to take something that is explainable that people are fairly familiar with to explain something that is not explainable that people are not particularly familiar with. There aren't a lot of things on this earth that would have been understood by people that just appear and disappear. A scroll would be something that I think people of that day would have understood as being laid out so that you can read all the text, but then, it is quickly rolled up and everything contained in the scroll has now disappeared to the eye.
However, the point is merely that the universe, it seems according to the Scriptures, is going to disappear about as fast as it came to appear. But I'm fine with however, the reality of the event actually comes to pass.
God bless you,
In Christ, ted
