Kyle Thompson // Mere Christianity: The Cost of Perfection
January 20, 2026

Overview

In this episode, co-hosts Joby Martin and Kyle Thompson explore the profound challenge and promise presented in C.S. Lewis's "Mere Christianity," focusing on the concept of the "cost of perfection." Through Scripture and Lewis’s words, the episode challenges contemporary Christian attitudes about self, sacrifice, and the totality of Christ’s call—all while equipping listeners to consider what it truly means to follow Jesus.

Key Discussion Points & Insights

1. Setting the Context (00:20)

Kyle Thompson introduces the theme: The hosts focus on "Mere Christianity" by C.S. Lewis, zeroing in on what Lewis says about the total demand of Christ.
- Reference to previous episode on natural law and the question: “Can we be perfect?”

2. Reading the Core Lewis Passage (01:10)

Kyle reads from Book 4, Chapter 8 of Mere Christianity:
- “The Christian way is different, harder and easier. Christ says, give me all... I want you… I have not come to torment your natural self, but to kill it. No half measures are any good... Hand over the whole natural self, all the desires which you think innocent as well as the ones you think wicked. The whole outfit. I will give you a new self instead. In fact, I will give you myself... My own will shall become yours.”
Key Insight:
- The call of Christ is absolute—He requires not just parts of us, but our entire selves.

3. The Individualism of Modern Culture vs. Lewis's Vision (02:00)

Kyle directly contrasts Lewis’s vision with modern culture:
- "Everything, like absolutely everything revolves around us. Our desires, our comfort, our aspirations, who we choose to have sex with, the political party that serves our needs best... You can just go into a lot of churches in the west actually, and you get the same thing, don't you?"
Observes a trend in churches where messages focus on self-gratification rather than surrender.
- “The sermons are very short on scriptural truths, but very long on life lessons that always seem to circle back to God being our little cosmic genie that gives us everything we want because we're so awesome…”

4. The Paradox: Easier and Harder (03:00)

Lewis describes the Christian life as "harder and easier."
- “What about Lewis's point that the Christian way is different somehow? Easier and harder at the same time?”

5. Scriptural Anchor: Matthew 16:24-28 (03:25)

Kyle reads Jesus's words:
- “If anyone would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake will find it. For what will it profit a man if he gains the whole world and forfeits his soul?”
- (Matthew 16:24-26, quoted at 03:25–03:45)
Notable commentary on Jesus's clarity:
- “I mean, Jesus really puts it on the bottom shelf for the apostles, right?”

6. The Apostles' Struggle & Human Nature (03:50)

Kyle notes the apostles’ recurring confusion, emphasizing empathy for their struggles:
- “We really do have to take it easy on the apostles. They seem to be confused literally all the time. But all of us would have been as well. We have to be very honest about that.”

7. The Requirement of Perfection & its Impossibility (04:30)

Four key questions articulating the heart of the episode:
- “What does it take to make it to heaven? Perfection.”
- “How can we judge whether or not we've attained perfection? The natural law and moral law of God.”
- “Is it possible to perfectly follow the natural law and moral law of God? No.”
- “So how can we be made perfect before a righteous and just and holy Father, God? The perfect righteousness of Christ.”
The cost of perfection: surrendering “every last part of us. Every thought, every deed. All of us for all of Christ.”

8. The Challenge: Is Jesus Who He Claims To Be? (05:13)

The episode ends with a pivotal question, hinting at the next conversation:
- “So if the claim is that Jesus of Nazareth is the only way to perfection, don't we need to make sure that he is who he says he is? More on that tomorrow.”

Notable Quotes & Memorable Moments

C.S. Lewis (read by Kyle at 01:15):
“No half measures are any good... I will give you a new self instead. In fact, I will give you myself.”
Kyle on modern church messages (02:35):
“The sermons are very short on scriptural truths, but very long on life lessons that always seem to circle back to God being our little cosmic genie that gives us everything we want because we’re so awesome.”
On the apostles’ understanding (03:55):
“We really do have to take it easy on the apostles... But all of us would have been as well.”
Synopsis of God’s Offer (04:50):
“What is the cost of this perfection? All of us. Every last part of us. Every thought, Every deed. All of us for all of Christ.”
On the central question for faith (05:36):
“If the claim is that Jesus of Nazareth is the only way to perfection, don't we need to make sure that he is who he says he is? More on that tomorrow.”

Welcome back to the show. This week we're looking at one of my favorite books from one of my favorite authors of all time, and that's mere Christianity by C.S. lewis. So specifically, we're going to dig into some passages from the book that, that really cut to the heart of a man and center everything on the gospel of Jesus Christ. So yesterday we talked about natural law, as we've seen in book one, chapter three of Mere Christianity. And I posed some questions at the end there. What are we supposed to do with the natural law of God? Like how are we supposed to perform now and can we be perfect? And today we're going to discuss that as we look at the cost of perfection. And in order to do that, let's read the following passage from book four, chapter eight of Mere Christianity. The Christian way is different, harder and easier. Christ says, give me all. I don't want so much of your time and so much of your money and so much of your work. I want you. I have not come to torment your natural self, but to kill it. No half measures are any good. I don't want to cut off a branch here and a branch there. I want to have the whole tree down. I don't want to drill the tooth or crown it or stop it, but to have it out. Hand over the whole natural self, all the desires which you think innocent as well as the ones you think wicked. The whole outfit. I will give you a new self instead. In fact, I will give you myself. My own will shall become yours. And guys, that's the deal. That's God's final offer. All of Christ for all of you. But this doesn't really jive with our modern sensibilities, does it? Right, because we live in a time in history and culture where everything, like absolutely everything revolves around us. Our desires, our comfort, our aspirations, who we choose to have sex with, the political party that serves our needs best. How we identify how our immutable characteristics either elevates or lowers us on the victim power hierarchy, right? And you can just go into a lot of churches in the west actually, and you get the same thing, don't you? The song seem to always be about how God is just so into us, right? The sermons are very short on scriptural. Truths, but very long on life lessons that always seem to circle back to God being our little cosmic genie that gives us everything we want because we're so awesome, you see, it's just, you know, the very air that we breathe. What about Lewis's point that the Christian way is different somehow? Easier and harder at the same time? And further, what about this offer, all of you for all of Christ, to which I would add, for all of time? Right. Well, Jesus had this discussion with his apostles and disciples while he was on this earth. So let's actually go to Matthew's gospel, chapter 16, starting in verse 24. Then Jesus told his disciples, if anyone would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it. But whoever loses his life for my sake will find it. For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul? For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done. Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom. I mean, Jesus really puts it on the bottom shelf for the apostles, right? Even so, do you think they got it? I mean, do you think they understood? I mean, evidently the, you know, evidence is pretty clear that, no, they didn't really understand it. The apostles were constantly confused by Jesus's teachings and parables, and they stepped out of line all the time. I mean, just before this section, Jesus told his disciples that he would suffer under the chief priests and scribes. He would be killed and he would rise from the dead after three days. To which Peter said that would never happen, which caused Jesus to severely rebuke him, saying, get behind me, Satan. And then apparently all the apostles just forgot that when what Jesus predicted actually happened. And again, we really do have to take it easy on the apostles. They seem to be confused literally all the time. But all of us would have been as well. We have to be very honest about that. But God makes himself explicitly clear throughout Scripture. What does it take to make it to heaven? Perfection. How can we judge whether or not we've attained perfection? The natural law and moral law of God. Is it possible to perfectly follow the natural law and moral law of God? No. So how can we be made perfect before a righteous and just and holy Father, God? The perfect righteousness of Christ and what is the cost of this perfection? All of us. Every last part of us. Every thought, Every deed. All of us for all of Christ. So if the claim is that Jesus of Nazareth is the only way to perfection, don't we need to make sure that he is who he says he is? More on that tomorrow.
