1. Hook the reader. Every good story needs a hook, including the spiritual story. Set up the spiritual story with an intriguing question and a clear goal. In The Sparrow, by Mary Doria Russell, we are first introduced to Father Emilio as a man who narrowly missed sainthood. He now lies in a hospital bed, sullen, uncommunicative and suspected of a terrible crime. The reader is left wondering how a godly man came to be in such a place and what his future holds now.
2. Lay the foundation for the spiritual resolution. Miracles and sudden moments of salvation may happen in real life, but will feel contrived in fiction. Not only that, but they can also be hurtful to those with unanswered prayers or who have had to work through long, hard years of healing. Build the steps toward a satisfying spiritual conclusion into the structure of the novel at every turn. The story has to earn its ending, so that when it comes, the reader will feel as if it couldn’t have worked out any other way.
3. Dig for deeper themes. As important as it is to show characters accepting the gospel or to ask where God is when it hurts, those themes are common. Most likely, your novel is preaching largely to the choir, so you need to find themes that speak to the deeper struggles and goals Christians are working on as well. What does it mean to live in the light of eternity? How does prayer shape us? How do you love your enemy? How do you love your neighbor as yourself? What does a character look like who has lived out the gospel daily? And so on. When you get those rare non-Christian readers, those themes might just speak more deeply to them about the gospel than the message they’ve likely heard before.
4. Be fair and truthful. I once heard a theologian say that we needed to compare the best of Christianity with the best of other religions, and if you’re going to look at the worst of, say, Islam or atheism, you need to be willing to look at the worst of Christianity. In the movie God’s Not Dead, when the atheist professor breaks down and admits that he’s a bitter atheist because God let his mother die, it didn’t ring true. The fact is, there are many atheists who have arrived at their worldview based on careful thought, however misguided we may believe them to be. They may also happen to make decent citizens and neighbors. And we’ve all found our share of gossips and control freaks in church. Don’t be afraid to mix it up. If you dig deeply, the light of Christ will show through all the more clearly because you’ve been honest.
5. Show the Sacrifice. From A Tale of Two Cities to Titanic, audiences have always stuck by a story that involves a heartfelt sacrifice. But it’s the core of a Christian story. Whether it’s an act of utter courage such as Hadassah going willingly to the Roman arena in Voice in the Wind or something more ordinary like Will laying down his pride to admit the ways he wronged his Amish relatives in Levi’s Will, it’s the sacrifice that makes the story work.
6. Show the Beauty. Sometimes writers take for granted that the resolution is what the readers want. Don’t forget to show them why they want it. Davis Bunn shows how a prayer that has been prayed for over two thousand years comes alive when his modern character prays it in Book of Dreams, as if the leaves overhead were chanting the prayer with the character. Stephen Lawhead describes an old saint lit from the inside out with God’s love in Merlin. These little moments that show the beauty of God’s ways clarify the spiritual goal all the way through the book.
