Here's an interesting video, posted at Emergent Village by Steve Knight. I think this is a question that we should never stop asking:
I particularly like Tony Campolo's point near the end:
The only description that Jesus gives of Judgment Day is [based on] how we treated the poor. On that day he's not gonna ask you theological questions... you know "Virgin Birth: Strongly Agree, Agree, Disagree, Strongly Disagree."... Here's what it's gonna be: 25th chapter of Matthew: I was hungry. Did you feed me? I was naked. Did you clothe me? I was sick. Did you care for me? I was an alien. Did you take me in? What you failed to do to the least of these, you failed to do it to me, because I'm not up in the sky somewhere, I'm waiting to be loved in people who hurt.
