His most recent nonfiction book "Keeping Faith: A Skeptic's Journey" draws on time spent living as a member of the monastic communities of the Trappist Abbey of Gethsemani in Kentucky and the San Francisco Zen Center as a means to examining what it means to a skeptic to have and keep faith. Keeping Faith weaves frank conversations with Trappist and Buddhist monks with a history of the contemplative life and meditations from Johnson's experience of the virtue we call faith. It received the 2004 Kentucky Literary Award for Nonfiction and the 2004 Lambda Literary Award for best GLBT creative nonfiction.
