Discuss pilgrims progress as an allegory?

The work is a symbolic vision of the good man's pilgrimage through life. The book is perhaps one of the mosr famous Christian allegories written. In The Pilgrim’s Progress, Bunyan emphasizes the power of the word, God’s or otherwise, in the pilgrim’s quest. First and foremost, the text abounds with scriptural allusions, which Bunyan's readers would have been very familiar with. Biblical literacy was of primary importance to the Puritans, and the weight of scripture cannot be underestimated. Indeed, almost the first image of the text is of Christian being affected to conversion by what he has read in his Book, which the reader can assume to be the Bible (13). Therefore, the Word of God is the catalyst of the entire plot.
