But we can be gracious and understand what people mean. When asking a question like which books have you read multiple times, you would expect a lot of answers like "The Bible", it's certainly the book I've read most often, far more than any other book.
Unfortunately there just isn't too much of a reason to re-read books other than absolute classics, for example Shakespeare also falls into the category of "should re-read", or perhaps favorite collections of poems, but again these would typically be classics (modern poetry, like modern literature, tends not to have a broad audience, or even bother with trying to reach a broad audience).
With the rise of alt-texts such as social media, blogs, online information sources - books have definitely taken a beating, as have the institutions that produce books. It only takes 10,000 book sales in one week to make a NYTimes best seller. There are 385,000 Bibles sold each week - and many more given away, 100 million Bibles are printed each year.
I wonder if, in the future, there will be bible-based video games and other entertainment that will take up the time people spend reading the Bible as there have been things like television and video games that have replaced many people reading things like detective stories or adventure/romance stories.
The Bible isn't it.
