Sexual Purity (Part 2 of 2)

Devotional

Day 1: Controlling the Body in Holiness, Not Passionate Lust

Sexual purity begins with recognizing our bodies as instruments of righteousness, not tools for selfish desire. Paul’s command to "control his own body" confronts the cultural lie that sexuality is a private matter. Holiness requires active restraint, redirecting natural urges toward God’s design. This isn’t about suppression but stewardship—treating the body as sacred, set apart for honor. Singles and married alike are called to this discipline, resisting the world’s normalization of lust. True freedom comes when we submit our physicality to Christ’s lordship. [01:19]

“Each of you should know how to control his own body in holiness and honor, not in the passion of lust like the Gentiles who do not know God.”
(1 Thessalonians 4:4–5, ESV)

Reflection: Where do you feel most vulnerable to passionate lust—in your thoughts, habits, or relationships? How might surrendering this area to Christ’s control bring deeper honor to God?

Day 2: Sex’s God-Given Context: Marriage as Holy Ground

God designed sex to flourish within the covenant of heterosexual marriage, a boundary that protects its sacredness. Outside this context—whether premarital, adulterous, or homosexual—it becomes a distortion of His purpose. Marriage is not a license for selfishness but a call to mutual honor, where physical intimacy reflects Christ’s faithfulness to the Church. Singles are not excluded from fulfillment; their unmet longings can fuel service and friendship. Holiness here isn’t a burden but a gift, shielding us from relational chaos. [04:13]

“Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.”
(Hebrews 13:4, ESV)

Reflection: How does your current view of marriage align with God’s design as “holy ground”? What adjustments might honor Him more, whether in singleness or marriage?

Day 3: Sexual Sin as Fraud Against a Brother or Sister

Sexual immorality isn’t a victimless act. It steals dignity, betrays trust, and violates what rightfully belongs to another. Adultery robs a spouse; pornography dehumanizes image-bearers; premarital sex hijacks a future marriage’s purity. Paul warns that such sin “wrongs” others, fracturing community. Even hidden lust defrauds by corrupting our capacity for selfless love. Every choice in this arena ripples outward—either harming or healing those God calls us to cherish. [13:09]

“That no one transgress and wrong his brother in this matter, because the Lord is an avenger in all these things, as we told you beforehand and solemnly warned you.”
(1 Thessalonians 4:6, ESV)

Reflection: Have you minimized how your sexual choices (or compromises) impact others? What step can you take today to protect another’s holiness?

Day 4: God’s Call: Not Impurity, But a Holy Life

God’s primary calling isn’t to a career or ministry—it’s to sanctification. Sexual purity is nonnegotiable for anyone claiming Christ’s name. The Spirit’s power enables obedience, but we must reject the lie that grace excuses ongoing sin. Cultures that abandon God descend into sexual chaos, yet the Church must model a better way. Holiness isn’t a one-time achievement but a daily surrender, trusting that God’s design brings lasting joy. To dismiss this is to reject the Giver of the Spirit Himself. [18:01]

“For God has not called us for impurity, but in holiness. Therefore whoever disregards this, disregards not man but God, who gives his Holy Spirit to you.”
(1 Thessalonians 4:7–8, ESV)

Reflection: Where have you subtly believed God “overlooks” sexual sin? How might embracing His call to holiness deepen your dependence on the Spirit?

Day 5: Confession Cleanses Secret Sins, Restores Joy

No one stands blameless before God’s standard of purity—yet grace meets us in honest confession. Mental lust, hidden affairs, or past regrets need not define us. Christ’s blood covers every failure when we bring it into the light. Pharisee-like self-righteousness is as dangerous as outright sin; both distance us from repentance. Freedom begins when we admit our need, trusting God to forgive and redirect our desires toward His life-giving purposes. [22:24]

“If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.”
(1 John 1:9, ESV)

Reflection: What secret sin have you rationalized or hidden? What practical step will you take this week to confess it and receive Christ’s cleansing?

Sermon Summary

Paul insists that each Christian must learn to control the body “in a way that is holy and honorable.” Romans 6 gives the larger frame, because the redeeming of a life is not simply the saving of a soul for forever, but the claiming of the whole person, body included. The body is not to be offered to sin as an instrument of wickedness, but to God as an instrument of righteousness.

Sex, in Paul’s instruction, has a God-given context, namely heterosexual marriage. Outside that context, Scripture names sexual involvement before marriage as fornication, sexual involvement beyond marriage as adultery, and homosexual practice as contrary to God’s revealed design. The clarity of Paul’s expression runs straight against the sex-crazed culture of Thessalonica, Corinth, and the present age, but the clash does not soften the command. The evil one takes poison and wraps it in beautiful gilding, but the poison still kills.

The single life is not treated as an exception to God’s purpose. God’s standard may be hard, and natural loneliness may bring acute pain, but rebellion creates deeper frustration than obedience. Sexual energy may be redirected into affectionate friendships and loving service, and Christ’s yoke is easy when submission is real.

Sex also has a God-given style, namely honor, holiness, and purity. Marriage is therefore not “a form of legalized lust.” The marriage bed must be kept pure, and the difference is vast between selfishly possessing someone and unselfishly loving, cherishing, respecting, and fulfilling that person.

Verse six removes the notion that sexual sin is merely private. Sexual sin cheats another person, because it takes what rightly belongs to someone else. It is an offense against God, against holiness, against the body, and against a brother or sister.

God does not shrug at what a culture normalizes. The Lord will punish such sins, and Romans 1 shows that part of divine judgment already appears when God gives people over to the sexual impurities they demand. “No sinful sex is safe,” because the issue is not technique but obedience to God.

The call of God is plain: not impurity, but holiness. The Holy Spirit is given presently and continually, not as a decoration on Christian profession, but as the divine power for sanctification. First John 1 leaves no room for Pharisaic pride or despair, because confessed sin is forgiven and cleansed. Secret sins must come into the open so that they may be forgiven, forsaken, and replaced by lives that learn how to please God.

Key Takeaways

1. Sex has a God-given context [04:13] Paul’s instruction does not treat sexual desire as dirty, but as designed. The boundary of marriage is not arbitrary restriction, but the appointed place where the gift can be received without fraud, shame, or rebellion. When the context is rejected, the gift is not liberated, but twisted against God’s purpose. [04:13]
2. Marriage is not legalized lust [11:46] Paul’s call to purity does not expire at the wedding threshold. Holiness and honor must shape sexual love inside marriage as much as chastity must guard life outside it. The difference between using a spouse and cherishing a spouse is the difference between selfish possession and covenant love. [11:46]
3. Sexual sin cheats another person [13:09] Verse six refuses the modern idea that private consent makes sexual sin morally harmless. Sexual immorality always takes what belongs to another, whether a future spouse, a present spouse, a family, or the body that belongs to God. Sin in this arena is not only indulgence, but fraud. [13:09]
4. God calls His people to holiness [18:01] Paul reduces the matter to one clear sentence: God did not call His people to impurity, but to a holy life. The search for guidance often becomes confused because the plain calls of God are neglected. Salvation, sanctification, suffering, service, and sacrifice bring many lesser questions into their proper place. [18:01]
5. The Holy Spirit is given now [19:37] God’s command does not leave the Christian stranded with willpower alone. The Spirit is given in the present tense, moment by moment, for obedience to the word of God. To make light of sexual purity is therefore not merely to dismiss a human rule, but to disregard the holy God who gives the Holy Spirit.

Bible Reading

1 Thessalonians 4:3-8
“For this is the will of God, your sanctification: that you abstain from sexual immorality; that each one of you know how to control his own body in holiness and honor, not in the passion of lust like the Gentiles who do not know God; that no one transgress and wrong his brother in this matter, because the Lord is an avenger in all these things, as we told you beforehand and solemnly warned you. For God has not called us for impurity, but in holiness. Therefore whoever disregards this, disregards not man but God, who gives his Holy Spirit to you.” [01:19]

Romans 6:13
“Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness.” [02:27]

Romans 1:24-27
“Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen. For this reason God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error.” [10:13]

1 John 1:9
“If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” [22:16]

Paul says that whoever disregards this instruction disregards not man but God. Why is that such a serious statement, and what does it reveal about the source of sexual ethics? [19:11]
Romans 1 connects sexual impurity with exchanging the truth about God for a lie. How does that help explain why sexual confusion is not only a moral issue, but also a worship issue? [16:36]
1 John 1:9 promises forgiveness and cleansing through confession. How does that keep a group from falling into either pride on one side or despair on the other? [22:16]

Sex has a God-given context in marriage. What pressures from the surrounding culture make that hard to believe or hard to obey, and where does that pressure show up most clearly in everyday life? [04:13]
Singleness can include real loneliness, and yet obedience is still good and possible. For those who are single, divorced, widowed, or waiting, what helps turn loneliness into faithful friendship and loving service rather than resentment or compromise? [07:06]
Marriage is not legalized lust, but a place for honor, holiness, and purity. For those who are married, what does it look like to cherish a spouse rather than use a spouse? Where might selfishness need to be named honestly? [11:46]
Sexual sin cheats another person. How might that truth change the way someone thinks about private fantasies, hidden messages, pornography, emotional affairs, or physical compromise? [13:09]
God gives the Holy Spirit presently and continually. When temptation feels stronger than resolve, what would it look like to seek the Spirit’s help in a concrete way rather than simply trying harder alone? [19:37]
Secret sins need to come into the open so that they may be forgiven and forsaken. Is there any area where honest confession to God, and perhaps to a trusted believer, needs to begin now? What makes that step difficult? [22:16]

Sermon Clips

The fact of the matter is marriage is not a form of legalized lust. Marriage as God intended is something that is marked by holiness and honor and that is to be part of sexual fulfillment within marriage. There is a vast distinction between the desire to possess somebody selfishly to one's own ends and the desire to unselfishly love and cherish and respect and fulfill the needs and the longings of that individual. [00:11:46]

We too must accept this apostolic teaching, however hard it may seem, as God's good purpose, both for us and for society. We shall not become a bundle of frustrations and inhibitions if we embrace God's standard, but only if we rebel against it. Christ's yoke is easy, provided we submit to it. It is possible for human sexual energy to be redirected both into affectionate relationships with friends of both sexes and into the loving service of others. Multitudes of Christian singles, both men and women, can testify to this. [00:07:37]

So much of what is offered up to us as wonderful literature or wonderful cinematography is nothing other than a deviation from God's intended plan and purpose. And the great subtlety of the evil one is that he takes that which is poison and he wraps it in some of the most beautiful concoctions and gildings so that the unsuspecting may eat of it and begin to die. [00:06:06]

Statement number one, sex has a godgiven context, namely heterosexual marriage. It is therefore forbidden in every other context. Prior to marriage, it is referred to as fornication. Irrespective of whether you're engaged, irrespective of whether you really like this girl, you really like this guy, you really think they're going to be your only one, la. That is absolutely verboten in scripture. [00:04:06]

Very clear and straightforward statement concerning the fact that the redeeming of our lives is a redeeming not simply of our souls which will live forever but the totality of who and what we are. And therefore, if our claim to have been radically changed by the power of the spirit of God does not put restraints upon and constrain the whole matter of human sexuality, then we're actually living in a fantasy world and our statements are unmatched by our lifestyle. [00:02:55]

The implication is very clear. Sexual sin is not only an offense against God, against holiness, against honor, against my own body. Sexual sin is an act of fraud against my brother or my sister because in engaging in that I take what is rightly theirs. [00:13:31]

And I'm going to just tell you something in passing that if you and I begin to focus on the clear things to which God has called us, to salvation, to sacrifice, to suffering, to sanctification, and to service, then many of the other things which are our preoccupation will actually begin to fall into line. [00:18:44]

In other words, in the call to sanctification, he doesn't leave us on our own. He gives us his holy spirit. He enables us moment by moment as we live in obedience to his word. He gives us the holy spirit. And says Paul, understand that the spirit that he gives us is holy. [00:19:42]

So sex has a god-given context namely heterosexual marriage. And his second statement is that sex has a god-given style namely honor and holiness and purity. That's what he says in verse five. He says, "In contrast to the heathen who do not know God and who live in passionate lust, the style in relationship to the enjoyment of God's purposes in this matter is one that is to be touched by and framed by all that is holy and honorable." [00:09:05]

One of the great indicators that a culture has turned its back on the knowledge of God that has been revealed is the sexual morass into which it falls. And it is arguable just whether the framework of Thessalonica or Corenth was any worse than that which we're dealing with in contemporary Cleveland this evening. [00:10:39]

Incidentally, there is a direct correlation between not knowing God and all of the chaos that follows from that. Paul is here referring not to uh the fact that somehow or another these people are unfortunate enough to be in this position, but rather he is referring to their blameworthy neglect of the revelation which has been given to them. [00:09:46]

The application of honor and holiness in the matter of sexuality in living in purity is applicable both to the single individual and is applicable within the framework of marriage itself. And for that reason uh the writer of the Hebrews says in Hebrews 13 and verse4 marriage should be honored by all and the marriage bed kept pure. [00:11:02]

Whatever we may want to say about this, it is hard to deny the clarity of Paul's expression. The sexual expression of love is within the God-given context of marriage. Well, what about single people? Someone immediately asks. And what a valid and vital question that is. [00:06:42]

It is referred to as fornication. It is a violation of all of God's intended purpose for sex. It is also a violation in the realm of adultery, namely the involvement sexually with somebody other than your marriage partner after you have been married. [00:04:51]

For if in learning to control our own bodies as men essentially in the matter of sexuality, there will be only one outlet for that and that will be within the framework of marriage as we will see. [00:02:04]
