“Some people take months, years, maybe even decades, during which they aren't sure whether they're on the outside of Christian faith looking in, or on the inside looking around to see if it's real. As with ordinary waking up, there are many people who are somewhere in between. But the point is that there's such a thing as being asleep, and there's such a thing as being awake. And it's important to tell the difference, and to be sure you're awake by the time you have to be up and ready for action, whatever that action may be.”
