Bono, lead singer of the band U2, recently said: "The most powerful idea that's entered the world in the last few thousand years—the idea of grace—is the reason I would like to be a Christian. Though, as I said to [U2 guitarist] The Edge one day, I sometimes feel more like a fan, rather than actually in the band. I can't live up to it. But the reason I would like to is the idea of grace. It's really powerful."
