This three-in-one volume by Oswald Chambers, recognized as an intimate companion of God, substantiates the very basis of the Christian faith. He upholds the moral and spiritual standing of Christians, despite challenges from today's secular, skeptical, and lawless rationalists. Here Chambers addresses the human needs to recognize the ethical demands of Scripture, and he challenges readers to act as Jesus did, in the power of His Spirit. Throughout these pages he upholds the ethical principles of the Christian life by promoting Christian thinking that leads to godly behavior.
