To me, cheap grace doesn’t mean that it didn’t cost much, so much as it isn’t worth much. Still, sometimes there is a connection. The price of a car repair, or a surgical operation, is affected by how deep into the inner workings the professional will have to go. If you don’t believe you have a deep problem, or if you believe it’s already been fixed, you won’t pay the price needed to fix it. If your problem is termites and you won’t fix it, eventually you won’t have a house. If your problem is spiritual, you can patch over the holes, keep the telltale sawdust swept away, and ignore the swarms each spring. But in the end you’ll have no place to seek refuge from reality.
