I've only read one of Don Miller's books (yes, it was Blue Like Jazz), but I've been reading his blog lately. He is, at least lately, real big on the idea that if your life is a good story, then it's a good life. I think this makes sense in an existential fulfillment way, but I'm not sure that's best. I know that, even before I read anything he ever wrote, I would try to find narrative threads in my life. People seek order and meaning, even if they're looking in random chaos, and that's all that is, even if life isn't actually random chaos. As a Christian, I believe God is working all things for the good of people who love him. Christians can and often do frame the history of mankind as one big narrative, as told by the Scriptures. Thanks to prophesy, we can know the ending, God creates the new heavens and the new Earth and dwells with his people in the New Jerusalem, while we're still in the story itself. That's different than framing your life as its own story. When I try to make my life a story, I make the story all about me, and that's not how it ought to be.
