Why Not Be Agnostic? [Questions That Haunt]

I realize that I’m overlapping questions. I didn’t get to answer last week’s question because Patheos blogs were down last Friday morning. I’ll respond tomorrow. But let’s not let that put us off of answering Judi’s question:

Recently have read a number of your blog entries. Grew up evangelical. Dealing with doubt. I’m trying to figure out why progressives hold to Christianity at all. Why not just be agnostic? I hope this question makes sense.

I know that some of you are agnostic, so you can tell us why you are. Or why you’re a “Christian agnostic.” Or an ignostic. Or an atheist. Tell us why!
