As a17th century English Puritan priest, John? Bunyan's masterpiece is beyond doubt. Bunyan tells the story of a Christian who went to heaven with the help of a dream. A man who is overwhelmed by his own burden reads in a book that his city will be destroyed by skyfire. The sudden news hit his heart and made him panic. Just as he was in a daze, he met a preacher, who pointed out that he must immediately start to flee from his hometown "the city of destruction" to "the city of heaven". So Christians began a difficult and lonely journey, passing through the quagmire of despair, the valley of humiliation, the valley of the shadow of death, the flashy market and the fortress of doubt, and finally reached the kingdom of heaven to meet its unparalleled glory.
Pilgrim's Progress tells Christians a simple truth in a vivid and direct style-a Christian's life is a life of fighting, and the kingdom of heaven is entered by hardworking people. Four hundred years have passed in the wind and cloud, but the truth in the course of pilgrim's progress remains forever.
