"...I hardly ever so longed to live to God and to be altogether devoted to Him; I wanted to wear out my life in his service and for his glory ..." David Brainerd. Introduction by John Macarthur. David Brainerd was devoted to live for his Lord. He lived a short life but in his four years as a missionary he was blessed with a period of revival amongst the Indians to whom he had been ministering. By considering the life of Brainerd this book will be of tremendous spiritual benefit to you as you read of a young man plagued with depression and yet made so effective under God.
