What are your top 5 books?
Just to start the discussion I think the top book should be the Bible. Preferably a version with no study notes and not additional comments so that you can just sit and read it. This way you can meditate on the text and the text alone. If you have been around me long you have heard me say that the trouble with study bibles is that most people read them from the bottom up to the top, rather than read them from the top to the bottom. In other words, too many times we read the notes without fully reading and meditating on the text.
I have nothing against study bibles and I have several. I recommend first, The ESV Study Bible, The MacArthur ESV Study Bible, and The New Open Study Bible. I do believe you shall at least one good study bible - just make sure you have a bible with no notes or comments in order to truly meditate.
Having said that, then, and realizing that is going to be every one's number one choice, what are your top 5 books in addition to your favorite study bible? Why are they your top five books?
