The atonement of Christ is the heart of Christianity. Christians are not only a people of the Book, but a people of the cross. In this accessible resource, author David L. Allen carefully summarizes the doctrine of the atonement, with definitions of key terms, discussion of key Old and New Testament texts, and a survey of the historical theories of the atonement. Addressing topics like the atonement's necessity, nature, intent, extent, and application, The Atonement answers questions such as, "is the atonement actual or potential?" and "is the blood of Christ wasted on those who are eternally lost?" This book will be a go-to resource for all those who wish to understand what Christ accomplished on the cross by his death.
