50 Christian Book Ideas, Organized by Genre (Steal These)

Every Christian writer I know has the same two problems in sequence. First: "I feel called to write, but I don't know what." Then, five minutes after they find the idea: "Someone's probably already written this."

Both problems have the same answer. Ideas are not the scarce resource. Your treatment of an idea is. "Prodigal returns home" has been written ten thousand times and will be written ten thousand more, because the far country looks different in every generation. So take any premise on this list, run it through your own life, your own church, your own questions, and it becomes yours.

A quick note on how to use this list: don't hunt for the perfect idea. Pick the one that makes you feel something (conviction, curiosity, a little fear) and write the first chapter. You'll know within 2,000 words whether it has legs.

Christian romance (the biggest shelf in the store)

1. A church worship leader and the sound tech who's been quietly in love with her for three years get assigned to plan the Christmas service together, the year both of them are ready to leave the church.
2. A widowed rancher hires a city-raised nanny who's running from a broken engagement, and the whole town of eleven hundred people decides they're getting married before either of them does.
3. Two rival wedding vendors, a florist and a photographer, keep getting booked for the same weddings. She prays about everything. He hasn't prayed since his brother died.
4. A missionary kid comes home to the small town she barely remembers and falls for the contractor restoring her late grandmother's farmhouse, along with the faith she thought she'd left overseas.
5. An Amish woman's rumspringa in the city lasts three years longer than planned. When her father's health brings her home, the man she almost married must decide what forgiveness actually requires.
6. A Christian bookstore owner and the skeptical journalist writing a story on the "dying Christian retail industry" argue their way into something neither expected. Closed-door, banter-forward.
7. Second-chance romance: high school sweethearts, now a pastor and a divorce attorney, meet again when she's hired to handle his church's legal trouble.
8. A deployed soldier and the woman who runs his hometown church's care-package ministry fall in love by letter. He comes home with an injury he never mentioned.
9. A grumpy Christian farmer enters a marriage of convenience to save the family orchard, with the sunshine-hearted preacher's daughter who suggested it as a joke.
10. Historical: 1870s Kansas. A mail-order bride arrives to discover her intended died of fever, and his stern older brother feels honor-bound to marry her instead.

Biblical fiction

11. The innkeeper's wife in Bethlehem. The census, the crowds, the knock at the door, told by the woman who found them the stable.
12. Rahab's story from her own mouth: what it costs to bet everything on a God your city is at war with.
13. A novel of the two years the demoniac of the Gerasenes spent telling the Decapolis what Jesus did for him, the first missionary to the Gentiles.
14. The wife of Noah. Building for decades while the neighbors laugh, told through her doubts.
15. Onesimus the runaway slave carries Paul's letter back to Philemon, the master he robbed. The whole novel is the journey home, ending at the door.

Contemporary Christian fiction

16. A megachurch collapses in scandal, and the story follows four ordinary members through the year after: the worship volunteer, the deacon who knew, the new believer, the pastor's daughter.
17. A hospice chaplain who's lost her own faith keeps doing the job because she's good at it. Her newest patient is the childhood pastor who taught her to believe.
18. Three generations of women run a diner in a dying mill town. When the youngest wants to leave for seminary, all the family's buried history about women and calling comes up with the biscuits.
19. A famous atheist podcaster's teenage son becomes a Christian, and the book alternates between their two points of view for one year.
20. A refugee family and the suburban church that sponsors them, told honestly from both sides: the casseroles, the awkwardness, the real cost of welcome.
21. A man gets out of prison after nineteen years, converted inside, and comes home to a town, a victim's family, and a church that have to decide if they believe in the gospel they've been singing about.
22. A small-town pastor discovers his predecessor kept a journal of every doubt he never preached. The novel weaves both men's stories fifty years apart.

Christian suspense and mystery

23. A church secretary who notices everything realizes the new elder's charity is laundering money, and no one believes the quiet woman who runs the copier.
24. Cozy mystery series starter: a retired missionary settles in a lakeside town and keeps solving crimes with the observational skills of someone who survived three decades on the field. Book one: the organist's "accident."
25. A Christian counselor bound by confidentiality hears something in session that could stop a crime. The whole thriller runs on that one ethical wire.
26. An investigative journalist sets out to debunk a small town's reported miracle and finds a cover-up designed to exploit it, and something underneath the fraud she can't explain away.
27. A youth pastor's teenage mentee disappears, and the search exposes what everyone in the church chose not to see. Redemptive, but unflinching.

Christian fantasy and speculative

28. A kingdom where the king's promised return is now openly mocked; the story follows the last three villagers keeping the watch-fires lit. Allegory in the Lewis lane.
29. A near-future where quoting scripture in public costs social credit. An underground network memorizes the Bible, one book per person, like living manuscripts.
30. Portal fantasy: two siblings from a church split into rival congregations fall into a world whose long division mirrors their own, and healing one requires understanding the other.
31. A guardian angel procedural: each chapter is one assignment, one human, one nudge at a time, building to a case where intervention is refused.
32. Science fiction: the first generation ship arrives at its destination and the colonists must decide which parts of the faith survived the 200-year voyage, and which parts calcified into something else.

Devotionals and Bible studies (pick a person and a season)

33. A 60-day devotional for the deconstruction years, written for people who still love Jesus but can't walk into a building yet.
34. "Ordinary Hands": 90 short devotionals on work (spreadsheets, dishes, diapers, commutes) as actual worship, not a metaphor for it.
35. A 40-day Lent devotional through the eyes of minor Bible characters: the boy with the loaves, Simon of Cyrene, the servant girl at the fire.
36. A couples' devotional for the hard seasons specifically: infertility, unemployment, caregiving, grief. One honest page per day, no clichés allowed.
37. A devotional for new mothers built around night feedings: 3 a.m. length, 3 a.m. honesty.
38. "Psalms for the Anxious": each entry pairs one psalm with one modern anxiety and one 5-minute practice.
39. A men's study on the Bible's failed fathers (Eli, David, Jacob) and what breaking the pattern costs.
40. A teen devotional written as 52 letters from an older believer who remembers being sixteen and doesn't pretend it was simple.

Christian nonfiction and teaching

41. A book on calling for people who hate their jobs and can't quit them: a theology of work for the stuck.
42. "The Ministry of Showing Up": on being the church member who isn't gifted, isn't called to lead, and matters anyway.
43. A practical book on church conflict that treats it as discipleship instead of crisis management, from someone who's survived a split and stayed a believer.
44. A book on money for Christians who grew up poor, addressing the shame and scarcity most stewardship books skip.
45. "After the Amen": what to do with unanswered prayer, written by someone still waiting, not from the other side of the miracle.

Memoir and testimony

46. The years your faith was on life support and what actually kept it alive (name the real things: a person, a habit, a stubbornness).
47. A memoir of leaving a high-control church without leaving Jesus, careful, specific, and free of revenge.
48. Raising a child with a disability and the theology you had to rebuild from the studs.
49. A mission-field memoir that tells the truth: the failures, the funding letters, the day you wanted to come home, and why the sanitized version helps no one.
50. The addiction-and-recovery testimony only you can write, structured around the scripture that found you at each stage.
