The lead singer of Jars of Clay, Dan Haseltine, has a blog that asks some really good questions, and just generally has a lot of good thought. Here's the link to it: Dan Haseltine's Blog
Disclaimer: a lot of the posts focus on art, and artists. Feel free to skip over stuff.

In addition, a friend of mine, and pastor of a church down the road from Newberry College (where I'm going), has a blog with some very good analyses and discussions. Here's the link to his blog: After Math

I'm kinda wondering whether we should have a separate forum for Christian blogs? I've found some really good stuff on blogs (as well as a lot of horrible stuff, too).
