This Is Why: Understanding God's Will for Sexual Purity

Behind enemy lines. That's where we find ourselves as followers of Christ in today's world. But let's be clear about what this means: we're not at war with people. We're at war with the ways of the world, the flesh, and our spiritual enemy. The people around us—our neighbors, coworkers, family members, even strangers—they're not the enemy. They're the very ones we're called to reach with the hope of Jesus Christ.

Our mission is to live as a testimony so compelling that others see something different in us, something worth pursuing. This is why how we live matters so profoundly.

The Universal Will of God

Throughout Scripture, we discover God's universal will for believers. We're called to believe in Jesus, to rejoice always, pray persistently, give thanks in all circumstances, and submit to doing good. These aren't suggestions—they're the foundation of Christian living.

But there's another aspect of God's will that demands our attention, one so specific that it stands out among the broader commands: sexual purity.

In 1 Thessalonians 4:3-8, we encounter a sobering truth: "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."

Why Sexual Sin Is Different

Of all the sins Scripture addresses, why does sexual immorality receive such pointed attention when discussing God's will? The answer lies in the unique nature of this sin.

Paul explains in 1 Corinthians 6:18-20: "Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body. Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies."

Sexual sin is an attack against personal holiness. It's not just a sin against another person—it's fundamentally a sin against God Himself. When we engage in sexual immorality, we're saying to our Creator: "I don't care about Your design. I don't care what You believe is best for me spiritually, mentally, emotionally, and physically. The most important thing to me right now is this moment of pleasure."

The Spiritual Dimension of Intimacy

Sexual intimacy, as designed by God, is far more than a physical act. At its core, it's a spiritual connection between two people united in marriage covenant—a covenant that includes God Himself. This beautiful design mirrors the relationship between Christ and His bride, the Church.

When we twist this gift, using it outside God's intended design, we damage something sacred. We block our spiritual maturity and affect not only our relationship with God but how we view Him. Sexual sin creates a barrier in our fellowship with the Father.

Think of it this way: when you receive an extraordinary gift, you value it. You read the instructions, follow the guidelines for care, and protect it. Yet many believers—and certainly unbelievers—treat God's gift of sexuality carelessly, ignoring the instruction manual He provided. We've twisted it, abused it, and devalued it.

The consequences are real and devastating.

The Pornography Epidemic

Today's statistics paint a disturbing picture. Seventy-nine percent of millennial men report watching pornography at least once a month, with most viewing it several times weekly. Sixty-four percent of women watch porn monthly. Among young adults aged 18-24, 22% consider pornography good for society.

Perhaps most telling: teens and young adults consider not recycling more immoral than viewing pornography.

Pornography robs us of life, pleasure, and oneness—the very things godly sexuality is designed to provide. It trains us to prefer fantasy over family, fatigues our brains' pleasure receptors through dopamine overload, and bonds us to images rather than to a real person. Studies show that viewing porn significantly lowers people's judgments about the attractiveness of average people, including their own spouses.

This isn't just a moral issue—it's a neurological one. Pornography rewires the brain, creating addiction patterns that numb us to real intimacy.

A Warning and an Avenger

The Scripture in 1 Thessalonians doesn't mince words: "The Lord is an avenger in all these things." Sexual sin doesn't just step outside God's will—it places us directly in His crosshairs. This is personal to God.

Consider King David's story. After his adultery with Bathsheba and the murder of her husband Uriah, David believed his sin was hidden. But when confronted by the prophet Nathan, David's response in Psalm 51 reveals the truth: "Against you, you only, have I sinned and done what is evil in your sight."

David understood that his sin against Bathsheba and Uriah was ultimately a sin against God Himself.

The Path to Restoration

But here's the beautiful truth: there is a way out. David's prayer in Psalm 51 shows us the path to restoration:

"Create in me a clean heart, O God, and renew a right spirit within me. Cast me not away from your presence, and take not your Holy Spirit from me. Restore to me the joy of your salvation and uphold me with a willing spirit."

God can create in us a clean heart. Through the power and authority in Jesus' name, we can overcome sexual sin. We can choose Jesus over our desires, our passions, and our fleeting moments of pleasure.

What are those moments compared to eternity with Him?

Living in the Light

Romans 13:12-14 calls us to action: "The night is nearly over; the day is almost here. So let us put aside the deeds of darkness and put on the armor of light. Let us behave decently, as in the daytime, not in carousing and drunkenness, not in sexual immorality and debauchery, not in dissension and jealousy. Rather, clothe yourselves with the Lord Jesus Christ, and do not think about how to gratify the desires of the flesh."

This is why we're called to live differently. This is why our lives matter as testimonies. When we abstain from sexual sin, when we control our bodies in holiness and honor, we demonstrate that we know God. Self-control over lustful passions becomes an indicator of genuine faith.

The Stakes Are Eternal

Jesus' words in Matthew 7:21-23 should shake us: "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven."

We can accomplish great things for God's kingdom—prophecy, cast out demons, perform miracles—and still not be in His will. A true believer lives in the will of God. Our house must be in order so nothing can be used against us, so we cannot be called hypocrites, so no one has grounds to testify against God's ways.

This isn't an impossible standard. Believe in Jesus. Rejoice always. Pray persistently. Give thanks in all circumstances. Submit to doing good. Abstain from sexual sin.

These are the markers of a life lived in God's will—a life that points others to Jesus, a life that makes a difference for eternity.

This is why.
