One of the best books I've read in the last year is Total Church: A Radical Reshaping Around Gospel and Community by Tim Chester and Steve Timmis. It is the best book on church I've seen yet.
This put me on to Tim Chester's blog. And I thought his recent posts on the rhythms of a missional church were excellent - biblical, concrete, practical. If you've been wondering what all this talk about being "missional" really amounts to, check it out.
Here's a link to the PDF that summarizes it all. But you should also check out Tim's blog.
