I think it's because books say a lot about those who's libraries they belong in. There have recently been a few videos on You-Tube looking around the studies of some well-known men. I thought I'd post a tour round half my library before these men of God - because mine's a lot smaller! (Half to three quarters of mine is housed in London at Lansdowne Evangelical Free Church). The noise is very poor but I focus on my favourite Holy Spirit books, preserved videos from Stoneleigh Bible Week and my Puritan collections;
Terry and Simon Virgo have been doing some interviews in Terry's study which I have loved. You also get a good glimpse at some of the wonderful books Terry has and reads.
Mark Dever's library is wonderfully massive and reminds me of Stanley Jebb's. I spied Richard Baxter's works which I have.
And again it was wonderful to see around John Macarthur's amazing study (although didn't see enough of it!);
Books are all very well and good - but if they do not serve in increasing a passion for a real encounter with the Presence of God then they are simply tools to increase intellectual snobbery.
