Ok, I have to break down and read some Flannery O’Connor. In the recent edition of Credenda Agenda, Douglas Jones has an article which talks about why many Christians get a little uptight about how O’Connor shows the grace of God in her novels. In short, our idea of grace is tied up in things which us feel good - not this “dark”, disruptive grace that O’Connor talks about :

Since Victorian times, Christians have tended to picture grace as cottony and covered with rubber. Grace always comforts and smoothes our furrowed brows; it always, always wipes away our tears, so sorry for them. We believe God is all-good; He’s pretty much a nursery-school attendant, pink and white, who doesn’t want anyone to get cut. In fact, we’re surprised when people actually bump their heads. Pain seems unnatural to us. It’s a no-no, and God is on our side. He never touches the stuff Himself.

In short, we believe deeply that all evil is bad. That’s the heart of modern Christian faith. All evil is bad. It permeates our day-to-day lives, our work, our sermons, our struggles, our analysis of disasters. All evil is bad. And if so, then grace has to be Nice. Grace and niceness become interchangeable, and Flannery sees this as a (if not the) chief source of wickedness in the modern world. It’s a lie about grace.

In Scripture, too, grace often appears evil. Sometimes it comes swooping down in the form of serpents. On the journey to Mount Hor, God’s people complained bitterly. Nice middle-class people, not criminals. Yet God’s dark grace came in horror story fashion: “The LORD sent fiery serpents among the people, and they bit the people; and many of the people of Israel died” (Num. 21:6). Imagine standing with that group of believers. Fiery serpents storm your spouse and children. All the screaming. All of grace. Surely fiery serpents were a bit of divine overreaction? God doesn’t want to upset anyone does He? No. Wrong God.

It is because of God’s grace that we experience most of the blessings that we do in this life. But they aren’t all cotton candy sweet. Sometimes, it takes something hard and dark to wrench our sight back to the source of all grace. Sometimes, grace isn’t what it seems.
