On the Mountain and in the Valleys, a journey with King David is a collection of sermons by Pastor J. D. Surbaugh; I pray this will be an encouragement to you as you read and study the life of David. We hope this book will serve new believers, laymen, leaders, and Frontline Messengers worldwide for years to come. May the Lord use this book to inspire, enrich, and empower all to grow stronger in the Lord. I am praying that people will not just read the words of this book but will experience God in a new way and develop a greater appetite for loving God and loving people.
