Upon what source did John Bunyan model his writing style in The Pilgrim's Progress?

Answer:
The English Bible
Explanation:
The English Bible has been used to influence John Bunyan's style of writing in The Pilgrim's Journey. The Pilgrim's Progress, published in 1678, is regarded as a Christian metaphor. John Bunyan was both a playwright and a Protestant preacher, which explains why his writings are all heavily inspired by religion.
