Brett McCracken recently wrote an article for The Online Wall Street Journal regarding how certain churches are trying to be more "cool" for the purpose of engaging their people.
Here's McCracken's conclusion:
If we are interested in Christianity in any sort of serious way, it is not because it's easy or trendy or popular. It's because Jesus himself is appealing, and what he says rings true. It's because the world we inhabit is utterly phony, ephemeral, narcissistic, image-obsessed and sex-drenched—and we want an alternative. It's not because we want more of the same.
