If you move in Christian circles today or have done so in the past ten years, you will be familiar with Rick Warren and his book, The Purpose Driven Life. A copy of that book sits to hand on my bookshelf as I type this. I confess I’ve struggled to read it from cover to cover, but it is there and it a useful introduction to faith, as the Alpha course was in its day. I ran across Warren on Newsweek’s Beast TV today, and in a short interview he has some interesting things to say about social media (he’s kidding about going to hell if you don’t follow him on Twitter … I think), the top two mistakes young people make, and the most countercultural thing you can say today.
