Grace Makes Holiness Possible: Fleeing Sexual Sin Together

Paul’s letter to the Corinthians lands like a hard progress report because chapters 5 and 6 refuse to gloss over what is broken. Paul confronts a church that tolerated sexual immorality so serious that even the pagan world around them would call it too far. The real scandal is not simply that sin existed among broken people who needed Jesus. The church’s arrogance, applause, or silence over that sin showed that it had confused kindness with passiveness and love with refusing to say anything.

Paul says the right response to what God calls sin is mourning, not celebration. The image of leaven shows why private, tolerated, unrepentant sin never stays private or contained. A little leaven works through the whole lump, and a little sin that a church ignores can slowly change what that church calls normal. The old leaven of malice and evil cannot fit with the new identity Christ has given.

Christ, the Passover Lamb, grounds the call to holiness in good news. His sacrifice makes people new, not their own effort or ability to clean themselves up. The clean break of Passover points to a clean break from the old life, because those in Christ are not who they once were. The question is not whether everyone else is doing it, but whether God is grieving over what people have quietly learned to excuse.

Paul then confronts the Corinthian misuse of grace. The claim that “all things are lawful” can sound like freedom, but freedom that leaves a person dragged around by desires and sin is not freedom at all. The body is for the Lord, and the Lord is for the body. Sexual union is not casual, neutral, or disposable because God designed it to form a real one-flesh bond.

Paul reframes the question from “What can I get away with?” to “How do I honor the One who bought me with a price?” The body belongs to Christ and is a temple of the Holy Spirit. Sexual sin is fully forgivable through Jesus’ blood, yet it carries a unique self-betrayal because it misuses a body that God has claimed as his dwelling place.

Paul’s command is not to negotiate with sexual sin, manage it, or see how close someone can get. His command is to flee. Fleeing means running from compromising relationships, private habits, and places of temptation, while also running toward accountability, community, and the Spirit who is present in the struggle. Grace does not make sin less serious, but grace does make holiness possible.

Key Takeaways

• 1. Mourn what God calls sin Paul refuses to let love become silence when sin is destroying someone. Mourning does not mean treating people as disposable or acting superior to them. Mourning means taking seriously what wounds people, dishonors Christ, and spreads harm through the community. [42:18]
• 2. Sin never stays merely private The leaven image confronts the belief that personal choices never affect anyone else. Hidden, tolerated sin slowly reshapes desires, relationships, and the moral instincts of a whole church. Truthful community breaks the loneliness that often keeps sin alive. [43:48]
• 3. Christ gives a new identity Christ, the Passover Lamb, has already dealt with the old life through his sacrifice. Holiness is not an attempt to earn a new identity but a response to the identity Christ has given. The old leaven does not belong to those whom Jesus has made new. [46:16]
• 4. Freedom must not become captivity Christian freedom is not permission to be dominated by appetite, habit, or desire. The question “What can I get away with?” keeps the heart centered on self. The question “How do I honor Christ?” recognizes that life and body belong to the One who bought them. [51:31]
• 5. Flee sin toward real community Fleeing requires more than removing a temptation because an empty life can quickly return to old patterns. Accountability, honest questions, and the presence of the Holy Spirit give fleeing a direction. Grace makes it possible to run toward life rather than merely away from guilt.

Bible Reading

1 Corinthians 5:1-8
“It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father's wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing. When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord. Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.” [37:30]

1 Corinthians 6:12-20
“All things are lawful for me," but not all things are helpful. "All things are lawful for me," but I will not be dominated by anything. "Food is meant for the stomach and the stomach for food"—and God will destroy both one and the other. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body. And God raised the Lord and will also raise us up by his power. Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a prostitute? Never! Or do you not know that he who is joined to a prostitute becomes one body with her? For, as it is written, "The two will become one flesh." But he who is joined to the Lord becomes one spirit with him. Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.” [48:58]

1 Corinthians 6:18-20
“Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.” [55:39]

Observation questions

1. In 1 Corinthians 5:1–8, what words does Paul use to describe both the sin in the church and the church’s response to it? [41:23]
2. What does Paul’s image of leaven communicate about what happens when unrepentant sin is tolerated in a community? [43:38]
3. In these passages, what reasons does Paul give for believers to live differently from their old way of life?
4. In 1 Corinthians 6:12–20, what contrasts does Paul make between what may be “lawful,” what is helpful, and what can dominate a person? [51:31]

Interpretation questions

1. Why is Paul especially concerned not only that sin exists in Corinth, but that the church is arrogant, silent, or approving about it? What does this show about the difference between patient love and passive love? [42:12]
2. Paul says Christ is the Passover Lamb and that believers are already “unleavened.” How does this gospel identity change holiness from trying to earn God’s acceptance into responding to what Christ has done? [45:41]
3. Paul says that the body is for the Lord and that believers have been bought with a price. How does this challenge the common question, “What can I get away with?” and replace it with a better question? [53:20]
4. Why might Paul’s command to flee sexual immorality require more than simply trying harder or removing one temptation? What does it mean to run toward something better? [58:22]

Application questions

1. Is there a sin, habit, attitude, relationship, or form of entertainment that has become so normal in the culture—or in personal life—that it is easy to stop grieving what God calls harmful? What would honest mourning look like in that area? [47:25]
2. When someone close is making destructive choices, what makes it difficult to speak truth with love? How can the group grow in being compassionate without treating silence as love? [42:33]
3. Where is the question “What can I get away with?” most tempting: with sexuality, money, words, time, alcohol, anger, entertainment, or something else? What would it look like to ask instead, “How can I honor Christ here?” [54:41]
4. Is there an appetite, habit, or desire that sometimes feels as though it is dragging you around rather than serving Christ? What is one specific boundary that could help you refuse to be dominated by it? [51:31]
5. Fleeing temptation includes identifying what to run from. What situations, private routines, apps, conversations, relationships, or times of day tend to make temptation stronger for you? What wise change could create real distance from that temptation? [57:52]
6. Fleeing also means running toward community and the Holy Spirit. Who could be a safe and truthful person to invite into a struggle, and what kind of honest question would be helpful for them to ask? [58:31]
7. Jesus’ blood fully covers every sin, and grace makes holiness possible. How does that truth help someone take sin seriously without being trapped in shame or hopelessness? [01:00:22]
