Hugh Hefner didn’t invent sexual sin. It is a problem that has been around since our ancestors walked east of Eden, and it will be around until the new Jerusalem descends upon us. The good news is that the Bible promises that we can experience foretastes of that coming freedom in the here and now. But how?

The Apostle Paul commands the Christians at Colossae, “Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry” (Colossians 3:5). But how do we do this? If we rip this verse away from the letter, we’re likely to apply it the wrong way, so we need to look closely to understand what Paul is talking about.

1. Fighting Sexual Sin Is Not About “Do More, Try Harder”

A dangerous philosophy was circulating in the church at Colossae that was championing asceticism: if you want to remain pure, then separate yourself from the pleasures of the body that are so often a source of temptation. This philosophy said if you really want the fullness of divine life within you, then insulate your life.

But Paul delivers a crushing blow to this philosophy:

If with Christ you died to the elemental spirits of the world, why, as if you were still alive in the world, do you submit to regulations—“Do not handle, Do not taste, Do not touch” (referring to things that all perish as they are used)—according to human precepts and teachings? These have indeed an appearance of wisdom in promoting self-made religion and asceticism and severity to the body, but they are of no value in stopping the indulgence of the flesh. (Colossians 2:20-23)

No value. That is Paul’s verdict on asceticism. It simply doesn’t work. Yes, there is a grain of truth in the philosophy—all popular philosophies contain at least some wisdom in them. If you are tempted to sin sexually then it makes sense to get away from sexual temptations. This will keep sin at bay—but ultimately the flesh remains unsatiated.

This false philosophy is still circulating in the church today. When the best advice we can give people is better Internet filters, cold showers, more hours in prayer, and trying harder, we have given into this philosophy that Paul says is of no value.

This false philosophy either totally underestimates the power of sin, or it sets the benchmark of holiness too low. It either doesn’t get just how ingrained sexual sin is in us, or it thinks that merely getting rid of outward, blatant sexual sin is the goal. Neither is accurate.

2. Fighting Sexual Sin Starts with a New Identity

Paul offers his readers another approach to fighting sin, and it starts with these core identity statements:

“With Christ you died to the elemental spirits of the world” (2:20)

“You have died, and your life is hidden with Christ in God” (3:3)

“You have been raised with Christ” (3:1)

“You were also raised with him through faith in the powerful working of God, who raised him from the dead” (2:12)

“Y ou have put off the old self with its practices and have put on the new self” (3:9-10)

“The riches of the glory of this mystery, which is Christ in you, the hope of glory” (1:27)

This is where a lot of modern readers check out. “Don’t give me these abstract theological ideas. I need something practical,” they think. But for Paul, there was nothing more practical, nothing more life-changing, than these ideas.

We are united to the risen Christ by faith. His resurrection life flows in our veins now. The Spirit of the living Christ lives inside us, so we no longer belong to this world and the rules it plays by—we belong to Christ and the age to come. In order to have the power to fight lust, we first have to understand this: we no longer belong to sin. We belong to God who has accepted us and forgiven us, not because we purified ourselves first, but because we are united by faith to the Pure One, Jesus Christ.

3. Fighting Sexual Sin Continues by Kindling New Desires

Knowing we are united to the living Christ, Paul writes, “Seek the things that are above, where Christ is, seated at the right hand of God. Set your minds on things that are above, not on things that are on earth” (3:1-2). The terms Paul uses here mean to center one’s interests, focus, and passions one something—to savor something. Now that God has united us to the risen Christ, we savor that reality, and this kindles new desires in us that displace a desire for sin.

What are these “things” above that we should savor?

First, we are to savor Christ himself. This is one of the reasons why Paul spills a lot of ink in this letter describing who Christ is. He is the beloved Son of God (1:13), the image of the invisible God (1:15), creator and sustainer of all things (1:16-17), the one whose blood reconciles us to the Father (1:20), the firstborn from the dead (1:18), and the one seated at God’s right hand (3:1). In him all the riches of wisdom and knowledge are hidden (2:3). The fullness of deity dwells in Him (1:19; 2:9).

Second, we are to savor our new position before God. Christ is seated at God’s right hand and we are seated with Him (Ephesians 2:6). To be seated at a ruler’s right hand meant to be in the position of greatest authority, honor, and delight. Because Christ is in us, we share in the favor He has with the Father.

Third, we are to savor the hope that some day we will see and experience these realities. Some day, Christ Himself will appear and we will appear with Him in glory (1:4). It is our destiny to be like the holy, pure Son of God. Some day our eyes will see the one who died for us and rose again, the one who is God in the flesh, and God will honor us as his royal children before every creature, every human soul, every angelic being in the universe.

How does this practically help us to fight sexual sin? The reason why sexual sin can have such a grip on us is because of its power to define us and what is most valuable, how sexual pleasure makes us feel about ourselves. Sexual fantasy, pornography, or pursuing illicit sex makes us feel desired; it makes us feel valued and validated; it gives us a refuge; it gives us connection; it can even make us feel powerful. This is why setting our affections on things above is so important: it gives us a new center to our lives and gives us a completely new sense of value—not based in our worthiness but based on the love God has for Christ that overflows to us.

4. Fighting Sexual Sin Is About Fighting For Our New Desires

Finally we come to Colossians 3:5, “Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry.”

Paul here is not endorsing asceticism—something he has already refuted. Asceticism is about fighting to get rid of something we think is unholy, but mortifying sin is about fighting for the new affections that God is giving to us.

We can construct helpful boundaries in our lives that keeps sexual sin out of reach, but we should do so standing on our identity as God’s beloved children, standing satisfied in Christ and God’s love. When sexual temptation comes knocking, we can say to it, “No, sin. That’s not who I am anymore. You do not define what life is to me anymore. You do not define me anymore. Christ is in me. I am a child of the king, and one day the whole world will know it.”

5. Fighting Sexual Sin Is Sustained by Relationships that Remind Us of Our New Identity

“Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God” (Colossians 3:16).

This is the essence of real accountability in the body of Christ. Yes, accountability involves confessing our temptations, sins, and the state of our heart, but it also involves godly encouragement. Accountability is not just about someone calling you out on your sin, but someone calling you up to the person you already are in Christ. Accountability is about surrounding yourself with the kind of Christian friendships that teach and admonish you, that inspire thankfulness, and that help us unpack all the wisdom contained in the great mystery that Paul called “Christ in us, the hope of glory” (1:27).

Accountability is like stoking the embers of the fire. It does not add energy to the embers. It only exposes those embers to the air so new reactions can happen. When we engage in the disciplines of confession, encouragement, and mutual prayer we expose our souls again to the life-changing gospel, and God’s power is released again and again.
