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 Come approaches 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.

Taking a holistic approach, the book explores the purpose of sleep, common causes of sleeplessness, and practical solutions for overcoming sleep struggles. It offers actionable guidance for caring for the body, improving sleep habits, and creating a restful environment, while also providing a framework for prayer and Scripture meditation to help readers find hope and true rest in God during sleepless nights.
