John Bunyan wrote a book in a jail cell. Honestly, that's the first thing you need to wrap your head around when asking what is Pilgrim's Progress about. He wasn't some academic sitting in a cozy library with a quill and a latte. He was a tinker—a guy who fixed pots and pans—imprisoned for preaching without a license. He stayed in that Bedford jail for twelve years.
It's a story about a guy named Christian. But it isn't just a story. It's an allegory, which is basically a fancy way of saying everything in the book is a giant metaphor for the internal struggle of being alive and trying to find a sense of purpose or salvation. Christian wakes up one day, realizes he’s living in the "City of Destruction," and decides he’s got to leave. He’s got this massive, invisible-yet-heavy burden on his back, and his family thinks he’s lost his mind.
He runs. He literally puts his fingers in his ears so he can't hear his wife and kids calling him back. It sounds harsh, right? But that’s the grit of the book. It’s about the desperate, sometimes messy pursuit of something better.
The Plot: A Messy Walk Toward the Celestial City
So, what is Pilgrim's Progress about in terms of actual events? Christian is trying to get to the Celestial City. Along the way, he meets people who are basically walking character traits. There’s Pliable, who’s down for the journey until things get slightly muddy. There’s Mr. Worldly Wiseman, who tries to convince Christian that he can get rid of his burden through "morality" and "legality" instead of the hard path of faith.
The most famous part of the early journey is the Slough of Despond. It’s a bog. A swamp of sadness. Bunyan describes it as the place where all the fears, doubts, and discouraging apprehensions of a sinner settle. Christian falls in. He sinks because of the weight on his back.

He eventually makes it out, thanks to a guy named Help. He reaches the Wicket Gate, meets a guy named Evangelist, and eventually finds his way to the Cross. This is the big moment. When he gets to the Cross, the straps on his burden snap. It rolls off his back and tumbles into a sepulcher. He never sees it again. But here’s the kicker: the book doesn't end there.
Most stories would end with the burden falling off. "And they lived happily ever after." Not Bunyan. He knew life is harder than that. The burden is gone, but the road is still long. Christian still has to deal with the Hill Difficulty. He still has to fight a literal demon named Apollyon in the Valley of Humiliation.
Why the Characters Feel Like People You Know
You’ve met these people. Seriously.
Talkative is that person at work who knows all the right buzzwords but doesn't actually do any work. Ignorance is the guy who thinks he’s doing fine just because he’s "a good person," ignoring the deeper requirements of the path.
Then there’s Vanity Fair.
This is arguably the most famous chapter in the book. Christian and his buddy Faithful walk into a town where there’s a year-round carnival. Everything is for sale. Houses, lands, trades, places, honors, preferments, titles, countries, kingdoms, lusts, pleasures. The people at the fair hate Christian and Faithful because they aren't buying what’s being sold.
It ends poorly for Faithful. He’s executed.
It’s a brutal reminder from Bunyan that staying true to your convictions often comes with a price. It’s not all sunshine and metaphors. It’s about the friction between a person trying to live a meaningful life and a world that just wants you to buy stuff and fit in.
The Psychology of the Burden
If you’re wondering what is Pilgrim's Progress about on a psychological level, it’s about the weight of conscience. Bunyan was obsessed with his own failings. He wrote another book called Grace Abounding to the Chief of Sinners, which is basically a memoir of his panic attacks and spiritual OCD.
The "burden" Christian carries is the weight of his own perceived wrongs. In the 1600s, that was framed as sin against God. Today, you might call it trauma, or the "Sunday Scaries" dialed up to eleven, or the crushing weight of modern expectations.
Whatever you call it, the feeling is the same: the sense that you are carrying something you weren't meant to carry, and it’s keeping you from moving forward.
The Places That Became Part of Our Language
Bunyan was so good at naming things that they leaked into the English language. Even if you’ve never read the book, you’ve heard the names.
- The Slough of Despond: That feeling when you’re so overwhelmed you can’t even move.
- Vanity Fair: Later used by William Makepeace Thackeray for his famous novel, and later by the magazine we see at every airport newsstand.
- The Valley of the Shadow of Death: Though originally from the Psalms, Bunyan’s depiction of it as a narrow, terrifying path with a pit on one side and a quagmire on the other cemented the imagery for centuries.
- The Delectable Mountains: Those moments of clarity where you can finally see where you’re going.
It’s wild to think that a guy with very little formal education created a geographic map of the human soul that we still use today.
Is It Only for Religious People?
Look, it’s a Christian book. There’s no getting around that. Bunyan was a Puritan. But here’s the thing: it’s also the first real English novel. Before Pilgrim’s Progress, most literature was high-brow stuff about kings and knights. Bunyan wrote about a guy named Christian. Not "Sir Christian" or "Prince Christian." Just a guy.
He wrote in the language of the common people. He used "kinda" (in 17th-century terms) instead of flowery prose. Because of that, the book crossed boundaries. It was translated into over 200 languages. It was often the only book, other than the Bible, that families in the American frontier owned.
Even if you aren't religious, the story hits on universal themes. Isolation. The need for companionship (Christian eventually gets a great travel buddy named Hopeful). The fear of death. The desire for a place where things finally make sense.

What Most People Get Wrong About the Ending
People think the book ends when Christian gets to the Celestial City. And for Christian, it does. He crosses the River of Death—which is deeper or shallower depending on how much faith you have in that moment—and enters the gates.
But Bunyan actually wrote a Part II.
Part II is about Christian’s wife, Christiana, and their kids. Remember how Christian left them? Well, Christiana eventually realizes he was right. She goes on the journey too. But her journey is different. She travels with a group. She has a protector named Great-heart.
It’s a much more communal story. While Part I is the lonely, terrifying struggle of an individual, Part II is about how we help each other get through it. Honestly, it’s the warmer, fuzzier sequel that makes the whole work feel complete. It shows that there isn't just one way to "make it." Some people run alone through the dark; some people walk together in the light.
Why You Should Care in 2026
We live in a world of "optimization." We have apps to track our steps, our sleep, and our productivity. We’re all on some kind of "journey."
But what is Pilgrim's Progress about if not a warning that the journey is supposed to be hard? It’s an antidote to the "hustle culture" that says you can just buy your way to happiness or "hack" your way to peace.
Christian doesn't have a map. He doesn't have a GPS. He just has a book and a goal. He fails. He gets locked in Doubting Castle by a Giant named Despair. The Giant tells him he should just end it all. Christian almost listens. Then he remembers he has a key in his pocket called "Promise."
That’s the core of the book. Even when you’re locked in the dungeon of your own head, you usually have the key. You just forgot you put it in your pocket.
Actionable Next Steps to Explore the Journey
If you’re interested in diving deeper into this story without getting bogged down in 17th-century "thees" and "thous," here is how to actually engage with it today:
- Read the "Plain English" Versions: Unless you’re a scholar, the original 1678 text can be a slog. Look for modern paraphrases like the one by Jean Watson or the "in Today's English" versions. They keep the grit without the headache.
- Watch the 19th-century Illustrations: Check out the engravings by William Blake or the brothers Rhead. They capture the "fantasy" element of the book. It’s basically the Lord of the Rings of the 1600s.
- Identify Your "Vanity Fair": Take a second to look at your life. What is the one thing—a social media platform, a habit, a social circle—that feels like a place where everything is for sale and nothing has value? Just recognizing it is a very "Christian" move.
- Listen to the Ralph Vaughan Williams Opera: If you want a vibe check, this musical adaptation is haunting and beautiful. It captures the "Delectable Mountains" feeling perfectly.
- Check Your Own "Burden": What are you carrying right now that isn't actually yours to fix? The book suggests that some weights can't be "managed"—they have to be dropped at the right place. Identifying that weight is the first step of the pilgrimage.
The story isn't a relic. It’s a mirror. Whether you view it as a spiritual guide or a foundational piece of Western literature, it’s a map of the human experience that hasn't aged a day.
