Andrea and I recently finished reading a very interesting book called "Jim and Casper go to church."  The book recounts the travels and experiences Jim Henderson (a regular Christian) and Matt Casper (a regular atheist) had as they visited 12 churches around the USA and entered into a discussion on what they found.   

There is tons of great stuff in this book (it's well worth the read), but the thing that I appreciated the most was the honest and perceptive feedback that Matt Casper had about Christians, and particularly about churches.  Here's a little section that I really enjoyed.  Jim writes:

"Casper had a number of questions for me before, during, and after each church we visited.  But the one question that was far and away the most difficult for me to hear was this one:  'Jim is this what Jesus told you guys to do?'   Casper saw and experienced - over and over and over again - what Christians do when they do church.  He saw it done with big budgets and no budgets, in large stadiums and in small buildings.  The same format repeated itself regardless of the setting.  The greet-sing-preach-collect-present form played out in front of us with unrelenting predictability.   And when it was all done, he would turn to me and ask, "Jim, is this what Jesus told you guys to do?"

If you're a follower of Jesus, I think you'll find Casper's observations really helpful - hearing what church looks like from an athiest's perspective.  I know it made me relook and rethink a ton of things that I tend to take for granted about how I look at faith and church. 

But I think this book would also be interesting if you consider yourself more of an agnostic or atheist.  One, you might find that Casper gives words to frustrations you've had about Christians and/or church.  But, two, I think you might find it refreshing to know that there are Christians like Jim (and me/us, hopefully) that are trying to do a better job of listening, and are searching for ways to authentically live out the life and message of Jesus.

If you want to check out the book, you should be able to find it at your local Barnes & Noble or online.
