This book is a collection of fifty-two devotions based on the Heidelberg Catechism, one of the foundational documents of the Presbyterian Church (U.S.A.). Former PC(USA) moderator Neal D. Presa begins each devotion with a few of the questions from the catechism, along with their Scripture references, and follows with a brief meditation on those questions. Presa's reflections tie the catechism questions to daily life in contemporary America, helping readers find meaning and relevance for their own lives. "Our Only Comfort" is a helpful resource for those interested in learning more about their Reformed heritage and how they can apply it to their daily lives.
