I loved this bit from a Philip Yancey interview on a U2 fan site, of all places:

“I tend to think that we humans are the only creatures in the universe concerned with what’s natural and what’s supernatural, what’s miracle and what’s not. From God’s perspective there is no ‘natural’ or ‘supernatural.’ Everything that happens is an outgrowth of what God set in motion. C. S. Lewis has a great passage where he describes miracles as ‘speeded-up ordinaries.’ When Jesus converted water into wine, he merely speeded up the process that has long been occurring, of rain and sun making seeds sprout and turn into vines that bear fruit that ferment and create wine. All of life is, in that point of view, a ‘slow-motion miracle.’ I like that. We keep yearning for the supernatural. I can barely handle the natural.”
