andrew brims (who i have not met but have liased with via e-mail) has just published a free ebook called unintended consequences. you can download a pdf here. it's beautifully put together, and explores the consequences of the current way of doing church. the implication is that we need a shift of imagination into a more missional way of being church. 

it's simple, makes a strong argument, has good ideas, and i hope will spark peoples imagination.

when talking about the way we do church it is really addressing contemporary evangelical charismatic churches but with a bit of imagining it's not hard to see that the same logic is not far removed from whatever flavour or stream of church – expensive to run with professional leaders, geared towards sunday services and growing the core through attraction, and all the energy goes into the services. do go and give andrew feedback. he'd love to hear from you.
