"Poetry is sane because it floats easily on an infinite sea; reason seeks to cross it and so make it finite... as long as there is mystery, there is health." ~ GK Chesterton This is another line used by Larry Crabb in his article from that journal. He is discusing the role of mystery in faith as his life experience has seen it be played out over the years. He says that he reached a point after about thirty years of being a Christian, where he just became disillusioned. One aspect he discusses is how he used to think of doubt as an enemy of faith instead of a doorway into deeper mysteries of it. DA Carson says that postmodernists fear certainty. I would add that in contrast, Christians fear doubt. The craziest part is that God is the end of both those fears if they are actually redeemed and followed out.
