John Bunyan 
The Pilgrim’s Progress [EPUB ebook] 

Often rated as important as the Bible as a Christian document, this famous story of man’s progress through life in search of salvation remains one of the most entertaining allegories of faith ever written. Set against realistic backdrops of town and country, the powerful drama of the pilgrim’s trials and temptations follows him in his harrowing journey to the Celestial City.
Although The Pilgrim s Progress was written more than three hundred years ago, this stirring spiritual narrative still bears the power to challenge and encourage readers on their own spiritual journeys.
