This past Sunday, we looked at Jesus’ sobering words in Matthew 5:27-30, where He takes the seventh commandment, “You shall not commit adultery,” and applies it to the heart. Jesus reminds us that God’s concern is not merely outward behavior but inward holiness. “Everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.” In a culture that often treats lust as normal, harmless, or even unavoidable, Jesus exposes it for what it truly is: a serious sin that corrupts the heart and dishonors both God and others.
One of the most important distinctions we made was the difference between temptation and lust. Temptation itself is not sin. Jesus was tempted in every respect as we are, yet without sin (Hebrews 4:15). Lust occurs when we embrace and cultivate sinful desires (James 1:14-15). It is the deliberate indulgence of sexual desire outside of God’s design for marriage. Likewise, sexual attraction itself is not sinful. God created men and women as sexual beings, and sexual intimacy within marriage is a good gift from Him (Genesis 2:24; Hebrews 13:4). Lust takes that good gift and twists it into something selfish, consuming, and destructive.
The challenge for many Christians is that lust can feel like a relentless battle. We live in a world saturated with sexual imagery and temptation. Yet Jesus does not leave us without hope. The same Savior who exposes our sin also provides the grace and power necessary to fight it (Titus 2:11-12). How then do we battle lust practically and biblically?
First, remember that fighting lust begins with fighting for the heart. Too often we focus exclusively on behavior modification while neglecting the deeper issue. Lust is not primarily an eye problem, a phone problem, or an internet problem. It is a worship problem. Lust is idolatry (Ephesians 5:3). It reveals misplaced desires and affections. We are often seeking comfort, excitement, pleasure, escape, affirmation, or control in something other than God. Lasting victory begins when we honestly ask, “What am I seeking from lust that I should be seeking from Christ?” Real change occurs when sinful desires are replaced by greater desires for God Himself.
Second, take temptation seriously and remove unnecessary opportunities for sin. Jesus’ language about gouging out an eye or cutting off a hand is intentionally shocking. He is not advocating self-harm but radical action against sin. If certain websites, apps, social media accounts, television shows, or situations consistently lead you toward temptation, eliminate them (Romans 13:14). Install accountability software. Set healthy boundaries on devices. Avoid situations where you know your guard will be down (Proverbs 4:23-27). Many Christians lose the battle because they underestimate the power of temptation and overestimate their own strength (1 Corinthians 10:12).
Third, pursue accountability and confession. Lust thrives in secrecy and isolation. Sin grows strongest in the darkness (John 3:19-20). James tells us to confess our sins to one another and pray for one another (James 5:16). Every believer needs trusted brothers or sisters in Christ who can ask hard questions, provide encouragement, and remind them of the gospel (Hebrews 3:13). Accountability is not merely having someone monitor your behavior. It is inviting others to help shepherd your heart. The goal is not shame but grace-filled honesty and growth.
Fourth, fill your mind with better things. Scripture repeatedly teaches that putting off sin must be accompanied by putting on righteousness (Ephesians 4:22-24). If we merely try to stop lustful thoughts without replacing them, we leave a vacuum. Saturate your mind with God’s Word (Psalm 119:9-11). Cultivate habits of prayer. Listen to sermons and worship music that direct your heart toward Christ. Memorize passages that specifically address purity (Philippians 4:8). The battle against lust is not won simply by saying “no” to sin but by increasingly saying “yes” to what is true, good, and beautiful.
Fifth, remember your identity in Christ. Many believers become discouraged because they continue to struggle. They assume repeated temptation means spiritual failure. Yet the Christian life is often marked by warfare (Galatians 5:17). Growth in holiness is rarely instantaneous. The goal is not perfection this side of heaven but faithful progress (Philippians 1:6). Remember the difference between justification and sanctification. Through faith in Christ, you have already been declared righteous before God (Romans 5:1). Your standing with Him does not rise and fall based on your latest victory or failure (Romans 8:1). At the same time, God is actively transforming you into the image of Christ (2 Corinthians 3:18). The direction of your life matters. A believer may stumble, but by God’s grace he continues pursuing holiness (Proverbs 24:16).
Finally, pursue a greater pleasure. The ultimate answer to lust is not merely stronger willpower but deeper satisfaction in God. Jesus said, “Blessed are the pure in heart, for they shall see God.” Purity is not simply the absence of sinful desire. It is the presence of a greater desire. The more we delight in Christ, the less attractive sin becomes (Psalm 16:11). Lust promises satisfaction but always leaves us empty (Proverbs 5:3-5). Christ offers joy that truly satisfies (John 6:35). The battle for purity is ultimately a battle for worship.
As followers of Jesus, we should neither minimize lust nor despair because of it. Christ died for this sin (1 Corinthians 6:11). He forgives it completely, and He empowers us to fight it faithfully (Romans 6:12-14). No matter where you find yourself today, there is grace for the repentant sinner, strength for the weary struggler, and hope for the ongoing battle. Keep looking to Christ. Keep pursuing holiness. And remember that the God who justifies His people is also committed to sanctifying them (1 Thessalonians 5:23-24).
