There is a wealth of great literature to study in the history of man, some written by Christians and some by non-Christians. While it is important to survey the writings produced in both the city of man and the city of God, the Christian student should direct special attention to literature produced in the city of God. The empires of man will always crumble and fall, but the kingdom of Jesus Christ will continue forever. This textbook covers four of the most important Christian works of all time. A thorough study of these great books will help the student understand the life, theology, and history of the Christian faith. This textbook covers Athanasius' On the Incarnation, A'Kempis' The Imitation of Christ, Calvin's Institutes of the Christian Religion, and Bunyan's The Pilgrim's Progress. Edition 3
