If you've been reading Christian blogs for a while, you will have very likely come across Jon Acuff's blog Stuff Christians Like. He's great at poking fun at the silly things that go on in the Christian community without being mean or sacrilegious. He's recently released a book which has some of the best stuff from the blog as well as some new material. You can download the audiobook of it for free at christianaudio.com/free. It's available free for this month only. I've listened to it already and really enjoyed it.
