Episode Overview

This special edition of Renewing Your Mind spotlights R.C. Sproul reading his children’s book, The Knight’s Map. Framed as both an engaging allegory and a teaching tool, the episode explores the trustworthiness of Scripture, equipping families—especially young listeners—with a parable illustrating the Christian journey. A post-reading interview with Dr. Sproul reveals the inspiration behind the book and explains its key symbolic elements, emphasizing the clarity and value of the Bible in guiding believers toward Christ.

Key Discussion Points & Insights

1. Skepticism and Trust in the Bible (00:07–01:39)

The story opens with the prevalence of skeptics who claim the Bible is outdated or unreliable—mirrored in contemporary society through media, academia, and peer groups.
Dr. Sproul aims to assure listeners, especially children and parents, that the Bible remains trustworthy and timeless.

“The world is filled with skeptics. You and I are surrounded by them... And even though they try to suggest… that the Bible is unreliable, it is trustworthy.”
—Host (00:52)

2. The Allegory: Sir Charles’s Quest (01:39–19:14)

The narrative follows Sir Charles, prompted by a mysterious letter and a map from the Great King, on a perilous quest to find the “Pearl of Great Price.”
Obstacles Along the Journey:
- Mr. Skeptic dismisses the map as outdated and useless (see 00:07; 01:39).
- Mr. Idol Maker promotes alternative treasures and easier paths.
- Mr. Liberal suggests an easy, broad road, which ends in disaster.
Sir Charles encounters Mr. Pilgrim, who introduces him to the Lampmaker (the Holy Spirit).
The Lampmaker explains the history of the map and the need for trust and obedience, drawing parallels to the biblical story of creation, fall, and redemption.
The story culminates with Sir Charles discovering that the “Pearl of Great Price” is not a physical treasure, but a person—the Prince, the Son of the Great King (a Christ-figure).

“If you, like Sir Charles, want to find the greatest treasure in all the world, you must learn as he did, to trust the map God has given you. That map is the Bible. It’s God’s way to lead us to his son. And you can trust everything it says.”
—Grandpa (18:45)

The parable is broken down for the family, clarifying its intent as an allegory for the Christian life and the Bible’s trustworthiness.

3. Behind the Story: Dr. Sproul’s Reflections (19:51–24:53)

Dr. Sproul shares his inspiration: Herman Melville’s Redburn, which critiques the usefulness of old guidance (the map) in a changed world.
The Knight’s Map responds to skepticism by affirming that God’s “map” (Scripture) remains applicable and dependable.
Sproul notes the intentional parallels to Pilgrim’s Progress, with Sir Charles facing adversaries like Mr. Skeptic and Mr. Liberal, echoing Christian’s journey in Bunyan’s classic.
The Lampmaker represents the Holy Spirit, who inspired, preserved, and enables believers to understand Scripture—not by imparting new meanings, but by illuminating spiritual truth.

“The lampmaker, of course, is the Holy Spirit… not only that, he is the one who illumines our minds to make it possible for us to understand the text of Scripture. It’s not that he adds any kind of new meaning… but he takes the scales off our eyes.”
—R.C. Sproul (21:54)

Drawing from Luther and the Reformation, Sproul underscores the clarity and accessibility of the Bible, able to lead even a child to Christ despite complex passages.

“The Bible is clear enough that it leads a six year old child to the Savior.”
—R.C. Sproul (23:41)

Notable Quotes & Moments

On skepticism and the Bible’s relevance:
“Why are you reading this old piece of paper? You can’t get any direction from this… You need to forget about this old map and find your own way.” —Mr. Skeptic (00:07; 01:39)
On trusting God’s word:
“If you follow the map, it will take you to the top of the mountain and the pearl of great price.” —Lampmaker (lampmaker as Holy Spirit) (story, ~15:00)
On the identity of the true treasure:
“I am the Pearl of Great Price… My father and I want you to know us… Come with me and I will take you to my father. His kingdom is just beyond this mountain.” —The Prince (~17:40)
Application to listeners:
“There will be people who will tell you not to trust [the Bible]… But if you…want to find the greatest treasure in all the world, you must learn as Sir Charles did, to trust the map God has given you.” —Grandpa (18:45)
On the Holy Spirit’s role in understanding Scripture:
“…he is the one who illumines our minds to make it possible for us to understand the text of Scripture.” —R.C. Sproul (21:54)

Finally, he set out on a journey toward the great mountain to find the Pearl of Great Price. Along the way, he came upon a man seated at the side of the road. His name was Mr. Skeptic. Sir Charles dismounted and asked for help in understanding the map. Mr. Skeptic quickly pronounced it worthless. Why are you reading this old piece of paper? You can't get any direction from this. He said. You need to forget about this old map and find your own way. And you certainly won't find the Pearl of Great Price. You're just wasting your time.

You're listening to a special edition of Renewing youg Mind, and I'm glad you're with us. Serving Christians at every age and stage of the Christian life is part of what we do here at Ligonier Ministries.

So I hope you'll gather your family together as R.C. reads the knight's map.

B (1:39)

The McFarlanes had family devotions. Every evening after dinner, they read the Bible, sang hymns, and prayed together. One evening, Donovan said, dad, the kids at baseball laugh and tease me and say we're old fashioned. They say we're wasting our time reading the Bible, that it's just an old book full of made up stories. Mr. McFarland smiled and said, son, that problem has been around for a long, long time. Many people have laughed at the B, saying it's not the word of God, that it's filled with myths and made up stories without meaning for us. Today, when Grandpa comes this evening, you can ask him. I think he might have an answer. Donovan and the rest of the children wondered what Grandpa might say. That evening, Grandpa had barely settled into his favorite chair before Donovan repeated his question. Do you think that we can really trust our Bible? Grandpa's eyes twinkled. He said, I just happened to have a story about that. Would you like to hear it? The children said, oh, yes, Grandpa, please tell us the story. And so Grandpa began. Many centuries ago, In a distant land there lived a knight. His name was Sir Charles, and he was a knight without a king. His neighbors told stories about the Great King. And there were rumors that he had created the land and the people. Others said there was no king at all, or that he was evil. All Sir Charles knew was that he had never seen the king. One day, Sir Charles received a letter. It was signed by the Great King, Sir Charles. The letter said, I am the Great King. I have known about you for many years. You will find a map included with this letter. It will lead you to the top of the tall mountain a few days journey from here. If you can follow this map, your reward will be great. You will find a wonderful treasure, the Pearl of Great Price. This treasure will last forever. It won't rust or fade away. Blessings to you on your journey. Sir Charles was confused. Could this letter really have come from the Great King? Did he even exist? And why would he write to Sir Charles? Despite these questions, something stirred in Sir Charles soul as he read the letter again. Perhaps it was true after all. His confusion only deepened when he looked at the map. It was beautiful, but also strange. Sir Charles found that he had trouble reading it. The language was majestic, but he couldn't understand what it meant. Days passed and Sir Charles could not get the map off his mind. Finally, he set out on a journey toward the great mountain to find the Pearl of Great Price. Along the way, he came upon a man seated at the side of the road. His name was Mr. Skeptic. Sir Charles dismounted and asked for help in understanding the map. Mr. Skeptic quickly pronounced it worthless. Why are you reading this old piece of paper? You can't get any direction from this, he said. You need to forget about this old map and find your own way. And you certainly won't find the Pearl of Great Price. You're just wasting your time. Taken aback by Mr. Skeptic's words, sir Charles pressed on, but soon felt growing doubts. That made it even harder to make sense of the map. As a result, he stumbled into a marsh and soon found himself hopelessly lost. After several days of wandering, he came upon a shop that specialized in selling idols. Sir Charles told the idol maker that he was trying to find the Pearl of Great Price, but was having trouble reading the map. Could he help? Mr. Idle Maker looked at the map and said it was unnecessary. There are plenty things that are just as good as the Pearl of Great Price, he said. Also, they are much easier to find. You can take any road you please and you are bound to Find one of them. Sir Charles was encouraged. He bid the man goodbye and took the first road he saw. It was not long before the road became overgrown with thorns and brambles. Soon it was completely choked. Sir Charles had to turn back. When he finally broke free of the tangle, he and his horse were bleeding and breathless. Returning to the base of the mountain, he met a man named Mr. Liberal. Sir Charles again asked for help in finding a way to the top of the mountain. Well, you certainly don't want to take the path with all the thorns and thistles and briars, he said. There's a much easier way to go. There's a wonderful highway just around the corner that's very broad, it's smoothly paved, the gate is wide, and there will be plenty of room for you and your horse. Sir Charles thanked the man and guided his horse through the wide gate and onto the broad highway. He was relieved there were no thorns or thistles to entangle him. He hoped he might reach the top of the mountain that very day. But after he'd gone many miles, he and his horse began to grow tired. Suddenly, without warning, the road ended in a cliff. If his trusty horse had taken even one more step, they would have plunged to their deaths. Stepping back from the edge, Sir Charles realized that there was no way forward, and he would once again have to return to the base of the mountain. He wondered if he should give up his quest. As he sat at the base of the mountain, wondering what to do, he was greeted by a man who seemed to be carrying all his possessions in a large pack. Sir Charles, as a last resort, asked the traveler if he knew how to find the pearl of great price. The man, whose name was Mr. Pilgrim, lowered his pack. Sir Charles, I can help you, he said. I've been sent by a very wise man. He can help you read the map and find the pearl of great price. I'll bring you to him. Sir Charles was astounded. He followed the man to a small cave in the side of a hill. Inside, he found an old man with a kind face seated at a workbench and tinkering with a lamp. Welcome, sir Charles. I've been expecting you. He said. I've brought you here because I understand that you're searching for. For the pearl of great price. The knight explained that he had received a letter and a map from the king, but nothing had turned out as he had hoped. The lampmaker smiled and said, if you want to find the pearl of great price and you want to get safely to the top of the mountain. You must trust the map the Great King gave you. Do you know who drew that map? The knight didn't know I did. Sir Charles was speechless. The lampmaker set down his tools and said, at the beginning of time, when the Great King ruled the First People, he set them in a beautiful park. The Great King gave them one restriction. There was one place in the park where they couldn't go, a small stone house. There were many things for them to enjoy in the park, but that particular house was off limits. He warned them that if they disobeyed, they would die. One night, a man entered the park. He was the king's enemy. And he said, the Great King is holding out on you. There are amazing things in that house that he doesn't want you to see. If you explore it, you will learn many things and become as wise as he is. The people believed the king's enemy and crept into the house one evening. The king's enemy had deceived them. The king found them in the house and they were banished from the park. Outside the park, they experienced great suffering, and eventually they would die. Do you see, Sir Charles? Their entire future depended on whether or not they trusted the king. And that trust was what the king's enemy attacked. But the king loved the people. So some time later, he sent his own son, the prince, to rescue them from the suffering they had endured and to bring them back to the park. The king loved the prince deeply and reminded him of their special relationship just before sending him to bring the people back. To accomplish his mission, the prince had to travel through a dreadful wilderness without food or water. There, the king's enemy waited until the prince was very thirsty. And then, using the strategy that had worked so well in the park, he cast doubt on the king and his words. He said to the prince, are you really the king's son? If you are, send someone for water. The prince replied, I must travel this road alone and without water. Obeying my father is more important to me than quenching my thirst. Leave me. That was the end of the discussion. And the prince went on to restore his people to the park, though at great cost to himself, just as he did with the First People. The king's enemy tried to tempt the prince by questioning the king's words. He said, if you are the son of the king, as if he might not actually be the king's son. The lampmaker paused and said, that map you have contains the Great King's words. I drew it exactly according to his instructions. And though the First People failed to listen to the words of the King. The Prince listened to his father. No matter what anyone said, that obedience cost him greatly. And when you find the pearl of Great price, I'm sure you will soon discover much more about the Prince. For now, you must take out your map, trust it, and follow it wherever it leads you. If you follow the map, it will take you to the top of the mountain and to the pearl of Great Price. Sir Charles thanked the old man and vowed that he would follow the map carefully. Sir Charles opened his saddlebag and took out the map. Now that he understood that the map contained the words of the great king, he found that he could understand it. Where once there had only been confusing language, he now found straightforward instructions. The path was clear. The map indicated only one road up the mountain. It was a narrow road and it had a small gate. Following the map, Sir Charles sought and found that very road. The way was steep. Sir Charles and his horse were forced to climb the difficult slope. But Sir Charles followed the map exactly. He didn't turn to the left or to the right, just as the old man had promised. The steep road took him all the way up the mountain. At the top, as he emerged into a clearing, he saw something extraordinary. It wasn't a pearl. Instead, he saw a man dressed in beautiful white robes, whose voice was like a thunderous waterfall. Sir Charles was terrified and sank to his knees, saying, who are you? The man said, I am the Prince, the son of the Great King. Sir Charles bowed his head and said, I received a letter from your father summoning me here. I am looking for the Pearl of Great Price. Can you help me? The Prince said, Sir Charles, my father and I provided you with the map and enabled you to read it. The map led you to me. I am the Pearl of Great Price. I don't understand, said the knight. Sir Charles, my father and I want you to know us. That's why we have called you. Come with me and I will take you to my father. His kingdom is just beyond this mountain. There you will dwell with us and. And we will dwell with you. Sir Charles rose unsteadily to his feet and the Prince took him by the hand. Together they set out for the kingdom beyond the mountain. The knight lived joyfully in the great King's kingdom, in the presence of the king and his son. And he was eternally grateful for the map that led him there. At that point, Donovan and the other children were wide eyed. Wow, what a story that was. Grandpa, they said. Yes, said Grandpa, of course. The night's Map was a picture of the Bible, the same Bible that your family reads every night. There will be people who will tell you not to trust it and to use something else to guide your life. But if you, like Sir Charles, want to find the greatest treasure in all the world, you must learn as he did, to trust the map God has given you. That map is the Bible. It's God's way to lead us to his son. And you can trust everything that it says.
