Letters on Living the Faith by C. S. Lewis

from $7.99
Hardcover:

What if C. S. Lewis himself could answer your hardest questions about faith? Letters on Living the Faith gathers his most intimate correspondence into one deeply personal guide to belief.

Jon M. Sweeney of Spirituality & Practice calls it "a creative and helpful example" of Lewis's writing that will "rightly take its place as a fresh offering in the Lewis canon."

Best known for The Chronicles of Narnia and Mere Christianity, C. S. Lewis spent decades corresponding with ordinary readers who wrote to him seeking guidance, comfort, and answers to their toughest spiritual questions. Letters on Living the Faith draws together the wisdom scattered across those personal letters into a single, thematically organized collection.

Editor David C. Downing arranges Lewis's counsel into three sections: prayer and Christian formation, practical faith and doctrine, and the confessions and questions readers brought to him, including many about Narnia itself. The result reads less like theology and more like spiritual direction from a trusted friend.

Lewis addresses doubt, grief, temptation, and the ordinary struggle of living out belief day to day, always with his signature clarity and warmth. Whether responding to a child's question about Aslan or a stranger's crisis of faith, he meets every correspondent exactly where they are.

For longtime admirers, this collection offers a more private, unguarded Lewis than his published works reveal. For newcomers, it's an accessible entry point into one of the twentieth century's most beloved Christian thinkers.

  • C. S. Lewis (1898–1963) was one of the twentieth century's most influential Christian writers and literary scholars. A longtime professor at Oxford and later Cambridge, he is best known for the beloved seven-book series The Chronicles of Narnia and for works of Christian apologetics including Mere Christianity, The Screwtape Letters, and Surprised by Joy. Alongside his published books, Lewis carried on a vast personal correspondence, often writing back to strangers who sought his guidance on questions of faith—the letters collected here.

  • Readers are calling it intimate, wise, and comforting:

    • Reviewer Jon M. Sweeney called the collection "a creative and helpful example" of Lewis's writing that "rightly takes its place as a fresh offering in the Lewis canon."

    • Readers single out a letter to Sister Penelope reflecting on approaching death, describing the experience as "sheer delight" and full of "solemn fun."

    • One reviewer praised the book for seamlessly bridging how Christianity can be approached both intellectually and pastorally.

    • Fans note the letters feel like Lewis is speaking directly to them, offering the same warmth found in his published books.

This book is for you if

  • You want spiritual guidance in C. S. Lewis's own words, not a scholar's paraphrase.

  • You're wrestling with doubt, grief, or the everyday work of living out your faith.

  • You love The Chronicles of Narnia or Mere Christianity and want to hear more of Lewis's voice.

  • You're drawn to letters and personal correspondence as a window into a writer's mind.

  • You're looking for short, thematically organized readings for prayer or reflection.
