I had a chance to hear Alan Hirsch and ask him a few questions at a dinner at the NNCC. On the plane ride back (with layovers) I'm reading through his book, The Forgotten Ways. If you blog, I'm sure you have seen a lot of conversation about it. I recommend you pick up a copy of the book, it is a very important voice in the conversation of the Western church.
