Traitor in the Tent

Introduction

Good morning, church. It’s so good to see you all.

Have you ever had one of those moments—one of those deeply frustrating, spiritually deflating moments—where you feel like you’re living a contradiction? You wake up in the morning, your heart is full of resolve. Today is the day. Today, you will be more patient with your kids. Today, you will not engage in that piece of office gossip. Today, you will control your tongue, you will guard your eyes, you will choose gratitude over grumbling. You have your quiet time, you pray, you feel aligned with God. You walk out your front door, spiritually armed and ready for battle.

And then, by 9:15 AM, it’s all come crashing down.

The kids spill a carton of milk, and the patient words you had planned evaporate into a sharp, exasperated sigh. You get to the office, and before you know it, you’re leaning in, listening to and maybe even adding to a story you know you shouldn't be a part of. A driver cuts you off in traffic, and a word escapes your lips that you definitely did not practice in your morning prayer.

You get to the end of the day, and you just hang your head. You think, “What is wrong with me? I love God. I want to follow Jesus. I know what is right. So why do I keep doing what is wrong?” It’s a profound and painful disconnect. You have the desire, but you lack the power. You have the information, but you fail in the implementation. It can feel like you’re a traitor to your own best intentions, a spy in the house of your own soul.

If that feeling is at all familiar to you, if you have ever felt that bewildering internal conflict, then the words of the Apostle Paul are going to land on you today not as a word of condemnation, but as a word of profound, empathetic, and ultimately hopeful recognition.

Our passage this morning comes from the book of Romans, chapter 7, beginning in verse 14. And if you have your Bibles, I invite you to turn there. As you’re finding it, I’ll tell you that for centuries, scholars and saints have wrestled with this passage. It is one of the most psychologically astute, brutally honest, and pastorally comforting sections in all of Scripture. Paul, the great apostle, the spiritual giant, pulls back the curtain on his own heart and shows us a struggle that is messy, raw, and startlingly familiar.

The title for our message today is “The Traitor in the Tent.”

We’re going to read what Paul writes, and as we do, we’re going to lean into our worship context for this series. We’re exploring the New Testament through the deep, ancient insights of the Old Testament and the Jewish world in which Jesus and the apostles lived. Today, to understand Paul’s agonizing cry in Romans, we need to understand a foundational Jewish concept that he would have been raised on since childhood—the idea of the yetzer hara, the “evil inclination.” It’s a perspective that will unlock this passage in a way that I pray will bring incredible clarity and freedom to your struggle. It will help us understand why, to put it bluntly, sinners wanna sin, even after they’ve been saved.

So, let’s read the Word of the Lord. Romans 7, starting at verse 14. Paul writes:

Romans 7:14–25 LSB

For we know that the Law is spiritual, but I am fleshly, having been sold into bondage under sin. For what I am working out, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate. But if I do the very thing I do not want, I agree with the Law, that it is good. So now, no longer am I the one working it out, but sin which dwells in me. For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the working out of the good is not. For the good that I want, I do not do, but I practice the very evil that I do not want. But if I am doing the very thing I do not want, I am no longer the one working it out, but sin which dwells in me. I find then the principle that in me evil is present—in me who wants to do good. For I joyfully concur with the law of God in the inner man, but I see a different law in my members, waging war against the law of my mind and making me a captive to the law of sin which is in my members. Wretched man that I am! Who will deliver me from the body of this death? Thanks be to God through Jesus Christ our Lord! So then, on the one hand I myself with my mind am serving the law of God, but on the other, with my flesh the law of sin.

This is the Word of the Lord. Thanks be to God.

To navigate this intense and powerful passage, we are going to take three essential steps together this morning. These are not steps to fix the problem, but steps to reframe the problem so we can receive God’s solution. First, we will Acknowledge the War. Second, we will Understand the Enemy. And third, we will Find the Liberator.

Background

Before we take our first step, we must paint the scene. To feel the full weight of Paul’s words, we have to see the man who wrote them. Forget the stained-glass image of a serene saint with a halo. Picture Saul of Tarsus. A man of blistering intellect and volcanic passion. A "Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for righteousness based on the law, faultless" (Philippians 3:5-6).

This was not a man who was casual about his faith. His entire identity, his sense of worth, his life’s purpose, was built on his ability to meticulously keep the Law of God. The 613 commandments of the Torah were not a burden to him; they were the scaffolding of his righteousness. He was, by all external measures, a moral and religious superstar. He was the guy who not only didn’t cheat on the test but who studied so hard he could write the textbook. His life was a testament to human effort and religious discipline.

Then, on a dusty road to Damascus, he has a blinding encounter with the risen Jesus Christ. His entire world is turned upside down. The righteousness he had spent his life building is revealed to be, in his own words, “garbage” compared to the surpassing worth of knowing Christ. He is transformed from Saul the persecutor to Paul the apostle.

Now, fast-forward a couple of decades. Paul is writing this letter to a fledgling church in the heart of the Roman Empire. This church is a messy, beautiful mix of Jewish believers, who grew up steeped in the Law of Moses, and Gentile believers, who were brand new to all of it. A central question for this community was: What is the role of the Law now that Jesus has come? Do we still need it? Is it a help or a hindrance?

Paul’s letter to the Romans is his magnum opus, a systematic, breathtaking explanation of the gospel. In chapters 1 through 3, he establishes a devastating truth: everyone, Jew and Gentile alike, is under the power of sin. In chapters 3 through 5, he reveals the glorious solution: we are justified, made right with God, not by our works but by grace through faith in Jesus. In chapter 6, he addresses a logical question: if we’re saved by grace, can we just keep sinning? His answer is a resounding “No!” We have been united with Christ in his death and resurrection; we are dead to sin and alive to God. We are no longer slaves to sin.

And right after that triumphant declaration, we hit chapter 7. And it feels like the brakes screech. After soaring to the heights of freedom in chapter 6, Paul seems to plummet into a pit of despair. He cries out, “I am unspiritual, sold as a slave to sin.” It’s a jarring transition. What’s going on?

Paul is doing something profoundly pastoral. He knows that after hearing about freedom from sin’s dominion, his readers will immediately bump up against the reality of sin’s presence. He’s saying, “Yes, you are free in Christ. But I know it doesn’t always feel that way. I know there’s still a battle raging inside you. Let me tell you, you’re not alone. I feel it too. Let’s talk about it.” He is diagnosing the ongoing struggle of the Christian life. He’s describing the civil war that erupts in the soul of every person who has been born again. The war between the new man who delights in God’s law and the old nature that is still very much present. This is not the testimony of a man before he was a Christian; this is the ongoing experience of a man who loves Jesus with all his heart but still lives in what he calls a "body of death." He is describing the traitor in the tent.

The ongoing internal struggle with sin is normal Christian experience, not proof that you are fake or unsaved.

Acknowledge the War

This is Step 1: To Acknowledge the War.

The first step toward sanity in the Christian life is radical honesty. It’s looking the struggle square in the face and calling it what it is: a war. Look at Paul’s language in verses 14 and 15:

Romans 7:14–15 LSB

For we know that the Law is spiritual, but I am fleshly, having been sold into bondage under sin. For what I am working out, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate.

Let’s break this down.

First, he affirms the Law. “The law is spiritual.” The problem isn’t with God’s commands. The Ten Commandments are not the issue. The Sermon on the Mount is not the issue. God’s standards are perfect, holy, and good. The problem, Paul says, is me. “But I am unspiritual.”

The Greek word here is sarkinos, which literally means “made of flesh.” It’s different from the word sarkikos, which means “dominated by the flesh.”

Paul is not saying he is an unregenerate person dominated by sin. He’s making a statement about his fundamental human constitution. He’s saying, “I still live in a body of flesh. I am a human being, with human appetites, human weaknesses, and a human history of rebellion against God.” This “flesh” or “sinful nature” is the beachhead that sin maintains in our lives even after we are saved. It’s the traitor that remains within the walls of the city, inside our tent.

And because of this fleshly reality, he feels “sold as a slave to sin.” Now, wait a minute.

Didn’t he just say in chapter 6 that we are no longer slaves to sin? Yes. This is the great paradox. Positionally, in Christ, before God, you are no longer a slave to sin. Your legal status has changed. You have been emancipated. But experientially, in your daily life, the old master, Sin, is still banging on your door, shouting commands, trying to drag you back into the slave quarters. And because a part of you—the flesh—still remembers that old master, you sometimes find yourself obeying its orders, even though you have a new, loving Master.

This leads to the bewildered cry: “I do not understand what I do.” Have you ever felt that? You look back at your own behavior—that flash of anger, that moment of selfishness, that lazy compromise—and you think, “That wasn’t the real me. Who was that?” It’s a feeling of profound internal alienation.

Paul gives voice to this universal Christian experience: “For what I want to do I do not do, but what I hate I do.” This is the classic statement of the divided will. There is a part of him, his renewed mind and spirit, that genuinely desires and delights in the will of God. But there is another part, his flesh, that gravitates toward the very things his spirit abhors.

The first crucial step for us is to simply acknowledge that this war is real, and it is normal. For too long, parts of the church have promoted a version of Christianity that suggests that if you are truly saved, or truly Spirit-filled, this struggle will simply cease. If you just have enough faith, if you just pray hard enough, if you just attend the right conference, you will achieve a state of perpetual victory where temptation is no longer a real threat.

Friends, that is not the picture the Bible paints. That is not the testimony of the Apostle Paul. And it is a deeply damaging teaching, because when people inevitably fail to achieve this state of sinless perfection, they are crushed by a double burden: the burden of their sin, and the burden of shame for not being a “good enough” Christian to have overcome it. They begin to doubt their salvation. They hide their struggles. They put on a Sunday morning mask and pretend everything is fine, while inside, the civil war rages, and they feel utterly alone.

Paul’s words here are a lifeline. He is saying, “Welcome to the club. Welcome to the normal Christian life.” The very fact that you are in this struggle is a sign of life! A corpse doesn’t struggle. A person who is truly and happily a slave to sin feels no conflict. They just sin. The conflict arises precisely because the Spirit of God has made you alive. You now have a new nature that is at war with the old. The battle itself is evidence that God is at work in you.

So the first step is to breathe. To stop pretending. To acknowledge the reality of the traitor in the tent. To confess, as Paul does, that there is a part of you that remains uncooperative, rebellious, and drawn to what you hate. Acknowledging the war doesn't mean surrendering to it. It means you’re finally ready to understand it and fight it with the right strategy and the right weapons.

Stop pretending you’re not in a war.

Acknowledge the traitor in the tent so you can fight with the right weapons.

Understand the Enemy

This is Step 2: To Understand the Enemy.

If we’re going to fight a war, we need good intelligence. We need to understand the nature of our enemy. Paul identifies the enemy with a single, chilling word: “sin living in me.” Look at verse 17 and verse 20. He says it twice for emphasis: “it is no longer I myself who do it, but it is sin living in me.”

What is this “sin living in me”? Is it a demon? Is it some external force that invades us? Paul’s Pharisaical background gives us a powerful lens to understand this. As a devout Jew, Paul would have been intimately familiar with the rabbinic concept of the yetzer hara.

The Yetzer Hara Explained

In ancient Jewish thought, it was understood that God created human beings with two competing inclinations or impulses.

There is the yetzer hatov, the “good inclination”—the impulse that drives us toward God, toward compassion, toward obedience to the Torah. And then there is the yetzer hara, the “evil inclination.”

Now, this is crucial. The yetzer hara is not “evil” in the sense that it is a demonic, external entity. The rabbis didn't see it as a personified Satan living inside you. Rather, they saw it as a fundamental part of the human design, a powerful, built-in drive for self-preservation and self-gratification. It’s the source of our basic appetites: the desire for food, for sleep, for wealth, for sex, for honor.

In and of themselves, these desires are not sinful. They are God-given. The desire for food keeps us alive. The desire for sex allows for procreation and intimacy in marriage. The desire for honor can drive us to achieve great things. The yetzer hara is like a wild, powerful horse. It provides the energy, the ambition, the drive of life.

The problem is that this powerful horse is wild. It is fundamentally self-centered. Left to its own devices, it will always choose me first. It will always seek its own gratification, regardless of God’s law or the good of my neighbor. The desire for food becomes gluttony. The desire for sex becomes lust and adultery. The desire for honor becomes arrogant pride. The yetzer hara becomes “evil” when it is not mastered and directed by the yetzer hatov, the good inclination that seeks to serve God.

The classic text for this in the Old Testament is found in the story of Cain and Abel. After Cain’s offering is rejected, he is furious. And God comes to him and says something profound in Genesis 4:7. “If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”

The Hebrew rabbis saw this as the definitive description of the yetzer hara. Sin is not some far-off concept; it’s a predator, crouching right at the door of your heart. It desires you. It wants to master you. And God’s command to Cain, and to all humanity, is “you must rule over it.” Your job, with the help of the Torah, is to take that wild horse of the yetzer hara and master it, to channel its energy for good, to make it serve the yetzer hatov.

The Law Cannot Tame It

Now, can you see how this illuminates Paul’s struggle in Romans 7? Paul, the Pharisee, spent his entire life trying to “rule over” his yetzer hara by meticulously obeying the Law. But he discovered a terrible and ironic truth. The Law, as good and holy as it is, doesn’t actually give you the power to tame the wild horse. In fact, it often makes the horse buck even harder.

This is what he means in verses 7 and 8 of this same chapter: “I would not have known what sin was had it not been for the law. For I would not have known what coveting was if the law had not said, ‘You shall not covet.’ But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting.”

It’s like putting a “Wet Paint” sign on a wall. What’s the first thing every child—and let’s be honest, many adults—wants to do? Touch it! The sign doesn’t create the desire, but it awakens and focuses it. The Law, by saying “You shall not,” draws a clear line. And the yetzer hara, that rebellious, self-centered impulse within us, sees that line and says, “Oh yeah? Watch me.” The Law, which is good, ends up provoking the sin that is latent within us. It exposes our inability to “rule over it.”

So, when Paul says, “it is sin living in me,” he is describing this internal, traitorous inclination. This yetzer hara. It is part of his human makeup, the “flesh.” It’s not the new man in Christ; it’s the old Adamic nature that has not yet been fully eradicated. It’s the part of him that is still bent inward on itself.

Understanding the enemy as the yetzer hara is incredibly helpful for two reasons. First, it depersonalizes the struggle in a healthy way. When you sin, it’s easy to think, “I am a terrible person. The real me is just rotten.” Paul’s distinction—“it is no longer I who do it, but sin living in me”—is not an excuse. It’s a theological clarification. He is saying that the truest you, the “inner being” that delights in God’s law (v. 22), is not the source of that sin. The source is this alien, indwelling principle of sin, this traitor in your tent. Your identity is in Christ, not in your struggle.

Second, it clarifies the nature of the fight. If the enemy is just “me,” then the solution is to try harder, to be a better person. But we’ve seen that this only makes things worse. But if the enemy is this powerful, indwelling inclination that I cannot master on my own, then I am forced to look for a power outside of myself. It forces me to stop asking, “How can I tame this wild horse?” and to start asking a much better question.

Understanding the enemy pushes me away from “try harder” religion and toward a Rescuer.

In the dense jungles of Lubang Island in the Philippines, a ghost haunted the local villagers for nearly thirty years after World War II ended. He would emerge from the jungle to steal food, burn rice fields, and occasionally engage in skirmishes with local police. This ghost was a real man: Second Lieutenant Hiroo Onoda of the Imperial Japanese Army. In 1944, Onoda and a small unit of soldiers were sent to Lubang with a simple order from their commanding officer: “You are absolutely forbidden to die by your own hand. It may take three years, it may take five, but whatever happens, we’ll come back for you. Until then, so long as you have one soldier, you are to continue to lead him. You may have to live on coconuts. If that’s the case, live on coconuts! Under no circumstances are you to give up your life voluntarily.” Onoda took that order to heart.

When the war ended in 1945, he didn't believe it. Leaflets dropped from planes announcing the surrender? Enemy propaganda. Newspaper articles left for him to find? A clever trick. Pleas from his own family broadcast over loudspeakers? A desperate enemy ploy. For 29 years, he continued to fight a war that was long over. He was living in a state of constant battle, hiding, foraging, fighting, completely enslaved to an old command and an old reality. His world was a world of war, while the rest of the world was at peace.

It wasn't until 1974, when his former commanding officer was flown to the island to personally and formally relieve him of his duty, that Onoda finally laid down his rifle. He had been fighting a phantom war, a slave to a conflict that had already been decisively won.

The Christian’s Struggle

This struggle Paul describes, this war with the yetzer hara, is like that. Christ has already won the decisive victory over sin and death at the cross. The war is, in a cosmic sense, over. Peace has been declared. And yet, like Lieutenant Onoda, we often find ourselves still hiding in the jungle of our own hearts, fighting skirmishes against an enemy whose power has been broken. We are still living by the old law of sin and death, still trying to survive on our own, still enslaved to a conflict that, in Christ, has already been resolved. The traitor in our tent, our sinful nature, keeps whispering that the war is still on, that we are still on our own, and that we must fight for our survival. It refuses to believe the news of peace. It keeps us trapped in the mindset of a slave, even though the Emancipation Proclamation has been signed in the blood of Jesus. The Christian life, then, is the long, slow process of learning to believe the war is over. It’s the process of allowing the news of Christ’s victory to penetrate every corner of our jungle-like hearts, to persuade the traitorous holdout within us to finally lay down its arms and walk out into the glorious light of peace.

Like Onoda, many believers live as if the war has not already been won in Christ—still fighting, hiding, and fearing under an old command from an old master.

Find the Liberator

Now that we understand that we are at war. We have identified who the enemy is, We can now move to Step 3: To Find the Liberator.

This brings us to the climax of the chapter, the cry that rips from Paul’s soul in verse 24. After describing this agonizing, unwinnable, internal war—the desire to do good, the practice of evil, the delight in God’s law, the imprisonment by sin’s law—he is brought to the end of himself. He is utterly spent. He has no strategies left. No three-step plans for self-improvement. He has acknowledged the war. He has understood the enemy. And the conclusion of his analysis is utter despair in his own ability.

So he cries out: Romans 7:24

Romans 7:24 LSB

Wretched man that I am! Who will deliver me from the body of this death?

Pay close attention to the question he asks. He does not ask, “What will rescue me?” He does not ask, “How can I rescue myself?” He asks, “Who will rescue me?”

This is the most important question a struggling Christian can ever ask. The answer to the problem of the traitor in the tent is not a principle, a program, or a technique. It is not a what or a how. It is a Who. The solution is a person. The solution is a Liberator.

For his entire life as a Pharisee, Paul’s question was always “How?” How can I be more righteous? How can I obey more perfectly? How can I master my yetzer hara? He was the man with all the answers, all the systems, all the discipline. And all it led to was a deeper awareness of his own failure. The road of self-effort, even with the best intentions, leads only to the cry, “What a wretched man I am!”

This cry of desperation is not the end of the Christian life; it is the beginning of a true one. It is the point at which we finally stop looking inward for a solution and start looking outward for a Rescuer. It is the blessed end of self-reliance. It is the death of pride. And only when we get to that point of absolute bankruptcy are we ready to receive the answer.

And the answer comes like a thunderclap of grace in verse 25: Romans 7:25

Romans 7:25 LSB

Thanks be to God through Jesus Christ our Lord! So then, on the one hand I myself with my mind am serving the law of God, but on the other, with my flesh the law of sin.

The rescue does not come from Paul. It comes through Jesus. The deliverance is not a reward for his struggle, but a gift he receives in the midst of it. The Greek word for “delivers” here is in the present tense. It’s not just “God delivered me once in the past at my conversion.” It’s a continuous action. “Thanks be to God, who is deliveringme, who keeps on delivering me, through Jesus Christ our Lord!”

How does Jesus deliver us? He doesn’t just give us a better rulebook for taming the wild horse of our sinful nature. He doesn't just offer tips on becoming a better rider. He does something far more radical. Through his Spirit who now lives in us, He begins to change the very nature of the horse from the inside out. He gives us a new heart and a new spirit.

This is the glorious transition from Romans 7 to Romans 8. Chapter 7 ends with the problem: “in my sinful nature a slave to the law of sin.” Chapter 8 opens with the solution: “Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit who gives life has set you free from the law of sin and death.”

The struggle of chapter 7 is real. The war is ongoing. The traitor in the tent is not immediately executed upon your conversion; it is placed on death row. It has been sentenced to death, its power has been broken, but its final execution awaits the day of our glorification, when we receive our new bodies. Until then, it will continue to rattle the bars of its cell, to shout lies, to tempt and to accuse.

Your job is not to find a way to kill it yourself. Your job is to stop listening to it. Your job is to turn your attention away from the traitor in the tent and fix your eyes on the Liberator who stands outside. Your hope is not in your ability to win the war in your heart. Your hope is in the One who has already won the war for your heart.

When you fail—and you will fail—the traitor will scream, “See! You’re a fraud! You’re a slave! God is angry with you!” But the Liberator says, “There is now no condemnation. You are mine. My blood covers that. Get up. My grace is sufficient for you. My power is made perfect in your weakness.”

Finding the Liberator means that every time you feel the pull of the yetzer hara, every time you do what you hate, your response is not to spiral into shame and self-flagellation. Your response is to run to Jesus. To thank God that deliverance is found not in your performance, but in His Person. The struggle of Romans 7 is designed to perpetually drive you into the arms of the Savior of Romans 8.

My hope is not that I will finally stop struggling, but that Jesus will never stop saving.

Conclusion

I know this struggle intimately. I know the gap between what I preach and what I practice. I know the frustration of Romans 7 not as a theological concept, but as a daily reality. I can study for hours, preparing a message on gentleness or patience, feeling so full of insight and resolve. And then I’ll go home, and something simple will set me off.

Just a few months ago, I was deep in study for a sermon, and my internet connection just died. I did all the things you’re supposed to do—restarted the router, checked the cables—nothing. So I had to call customer service. And I got put into one of those automated phone-tree labyrinths. “Press 1 for billing. Press 2 for technical support.” I went through layers of it, was on hold for twenty minutes listening to terrible music, and finally got a human being on the line. And before he could even get his full greeting out, I just let him have it. I wasn’t yelling, but my tone was sharp, impatient, demanding. I was treating him not as a person, but as an obstacle to me getting my work done.

After I hung up, the silence in my office was deafening. And the irony was just crushing. Here I was, a pastor, a man who is supposed to be a model of the fruit of the Spirit, and I had just been utterly unkind to a stranger on the phone over something as trivial as an internet connection. The traitor in my tent had won that skirmish, hands down. My yetzer hara—my desire for my work to go smoothly, my desire to be in control—had completely overpowered my desire to love my neighbor. And in that moment, I felt like a complete hypocrite. I felt, in my own small way, “What a wretched man I am.”

But the gospel truth that we have talked about today is what saved me from despair in that moment. My hope is not in my ability to be a perfectly patient person. My hope is not in my flawless execution of the Christian life. If it were, I would be lost. My hope is in my Liberator. My hope is that when I fail, I can immediately turn to Jesus and say, “Lord, have mercy on me, a sinner. Thank you that your love for me is not based on my performance. Thank you that your blood covers even this ugly moment of impatience. Please rescue me from me.”

That is our hope. Not that the war will cease tomorrow, but that our Liberator is with us in the trenches today. Not that we will become perfect, but that we belong to the One who is. The goal is not to stop struggling, but to learn to struggle toward Him. To let every failure, every frustration, every encounter with the traitor in our own tent, become another reason to fall on our knees and say, “Thanks be to God, who delivers me through Jesus Christ our Lord!”

Let that be the cry of our hearts today. Let’s turn from our performance and find our rest, our hope, and our life in Him.

Prayer

Father, we come before you now with honesty. We are the people of Romans 7. We feel the war within us every day. We confess that we are tired of fighting in our own strength.

Lord, help us, first, to Acknowledge the War—to be honest about our struggles without shame and to see the battle itself as a sign of your life in us.

Second, help us to Understand the Enemy—to recognize that indwelling sin, that traitor in the tent, and to stop believing its lies that our struggle defines us.

And finally, Lord Jesus, we turn our eyes to you. Help us to Find our Liberator in you. In every moment of failure and frustration, draw us out of ourselves and into your sufficient grace. Thank you that our rescue is not a what or a how, but a Who. And His name is Jesus.

It is in His precious and powerful name we pray, Amen.
