Many Christians are familiar with The Pilgrim's Progress, John Bunyan's (1628-1688) famous book written from a prison cell, which portrays the Christian life as one traveling from the City of Destruction to the Celestial City. During Bunyan's life, however, he produced nearly sixty books and tracts. Roger Duke and Phil Newton, with Drew Harris, trace the significant events that shaped Bunyan's life and thought in a biographical introduction and, in thirty-one excerpts from a variety of this great man of faith's writings, give us a glimpse of his piety, which flowed from his desire to venture all for God.
