Bono said this quote

“ Belief and confusion are not mutually exclusive; I believe that belief gives you the direction in the confusion. But you don't see the full picture. That's the point. That's what faith is. You can't see it. It comes back to instinct. Faith is just up the street. Faith and instinct, you can't just rely on them. You have to beat them up. You have to pummel them to make sure they can withstand it, to make sure they can be trusted. ”
