When Sleep Won't Come
Blending medical insight with biblical wisdom, physician and pastor Matt Rehrer explores both the physical and spiritual reasons why we struggle to sleep. Our struggles with sleep impact every area of life, from physical and spiritual health to emotional well-being and thinking clearly. When Sleep Won’t Comeapproaches sleep from both physiological and biblical angles to help us understand our bodies’ physical rhythms and needs and to show how God uses sleep and sleeplessness to reveal his grace and care. Sleep is not just a complex biological rhythm of the body but a spiritual rhythm of the soul and a divine gift that reveals our human limitations and dependence on God. Dr. Rehrer shares his personal experiences with sleep challenges and provides readers with tools to better understand their sleep patterns, manage stress, and find rest in the God who never sleeps. With clarity and compassion, he explains how sleep works, why it often fails, and what our restless nights reveal about both our bodies and our souls.

“I was pleased to learn that in this book, Matt Rehrer brings both medical and theological expertise to the matter. He addresses the whole person and offers a whole solution. And for that reason, I can give this book the praise that only a writer on this subject wants to hear: Read this book, because it may just put you to sleep.”

"Matt Rehrer has his finger on the pulse of the mystery of sleep by contributing a multifaceted explanation for what can make sleep so elusive. He introduces us to copious amounts of Scripture that provides insightful, informative, and practical wisdom regarding sleep! Matt Rehrer’s work offers discernment and hope for those who wrestle quietly in the dark for genuine rest.”

"With clarity, wisdom, and experienced care, [Rehrer] skillfully weaves together the science of sleep and the theology that gives it meaning. Rehrer offers far more than practical guidance for better rest; he reminds us that sleep is one of God’s daily invitations to relinquish control, embrace our creaturely limits, and trust the God who faithfully watches over us day and night.”

“Sleep. We think little of this thing we do so much. Thank God for Dr. Matt Rehrer’s impressive grasp of medicine, Scripture, and the human body. Clear, winsome, biblical, and practical, this book turns our attention to the wonder of God’s design for slumber and invites moments of worship along the way. If you struggle to sleep—or love someone who does—this book would be a timely gift.”

Reviews
"The founder of Netflix famously said that his company’s biggest competitor is sleep. While Netflix might keep you awake more than you should be, there are many other factors that contribute to sleepless nights. My friend Matt Rehrer (pastor and M.D.) has written a new book to help us understand the tension between our bodies and our souls and the true rest found only in the Lord who never sleeps."
“When Sleep Won’t Come is a huge blessing to Christians and will help answer the gnawing questions, both physically and spiritually, as to why sleep evades us and how we can serve the Lord in both restless and restful nights. As the kids say, ‘Don’t sleep on this book’…unless you plan to use it as a pillow, in which case I think Matt would be very glad you did."
