I'm going to be extra-American and gush for just a second about Mikey Lynch -- I think his blog, Christian Reflections, is one of the most quietly impactful blogs going right now in Theology Land. Mikey doesn't feel compelled to make a bunch of high-falutin' theological points or write a sermon for every post, but in the meantime he's evaluating and making connections in an incredibly smart way. Just about everything he writes I wish I had written instead, that jerk.
Anyway, take a look at his series on Crowded House, which is full of alternately fascinating, funny, and important insights. Here's Part 1, Part 2, and Part 3. Check back for more of his thoughts -- I know there will be a Part 4!
