Borrowed Light: A Trinitarian Approach to Christian Writing invites readers to see writing not merely as a technical skill, but as a gift shaped by the truths of the Christian faith. Amy Crider and Jonathan Pennington present nine theologically grounded principles that form a creative and biblically faithful approach to the craft of writing. Drawing inspiration from the architectural beauty of the Sainte-Chapelle in Paris, the authors offer a compelling framework that connects theological reflection with practical guidance. Like light passing through stained glass, Christian writing becomes a means of reflecting divine truth to the world. Borrowed Light equips writers to develop clarity, creativity, and conviction while cultivating spiritual formation in both the writer and the reader.
