Prodigals, Deacon's and Facebook

Tim Keller's new book called the Prodigal God is listed on Amazon for pre-order. Out in October. Found this post on what it means to be a 'Deacon' which was insightful. Also, listened to an interesting sermon about Facebook, Teens and New Technology which is called Push-Back Part 5 and I think it would be good for anybody trying to understand all this stuff in a biblical context.
