The Pilgrim's Progress from this world to that which is to come, delivered under the similitude of a dream, by John Bunyan

Since its first publication in 1678, The Pilgrim's Progress has never been out of print -- and that fact reflects the timeless relevance and wisdom of this long-form Christian allegory. The text follows the journey of the title character, Christian, as he makes his way from the earthly sphere represented by the "City of Destruction" to the "Celestial Sphere," which represents Heaven, battling sin, temptation, and every other conceivable vice along the way.
