How does John Bunyan’s Pilgrim’s Progress use a journey as an allegory for Christian salvation?

John Bunyan’s The Pilgrim’s Progress utilizes the allegory of a physical journey to represent the spiritual process of Christian salvation. By framing the protagonist’s trek from the City of Destruction to the Celestial City as a literal pilgrimage, Bunyan maps the internal struggles of faith onto external obstacles and encounters.12

The journey serves as a symbolic structure for the following stages of salvation:

• The Burden of Sin: Christian begins his journey weighed down by the burden of his sins, which he seeks to shed after reading the Bible. This burden physically falls from his shoulders when he reaches the Cross, signifying the reception of Christ’s free pardon.12
• Trials and Temptations: The road is filled with giants, monsters, and deceptive characters like Mr. Worldly Wiseman, representing spiritual terrors and the dangers of moral compromise. These encounters illustrate the ongoing struggle against temptation that persists even after one has entered the path of grace.12
• The Necessity of Faith: The journey is not merely a test of endurance but of faith. Whether navigating the Slough of Despond or escaping Doubting Castle, Christian must rely on divine guidance and spiritual tools, such as the key of Promise, to progress toward his ultimate goal.12
