Is Lust a Sin?
Jesus explicitly condemned lust in the Sermon on the Mount: 'Anyone who looks at a woman lustfully has already committed adultery with her in his heart.' Lust is listed among the sins that defile a person. Catholicism considers lust one of the seven deadly sins.
The fact that you're reading this is a sign.
Sin doesn't announce itself — it whispers. C.S. Lewis reveals how the enemy operates inside your mind, and how to fight back before it's too late.

In-Depth: Christianity Perspective
Christianity takes an uncompromising stance on lust. In the Sermon on the Mount, Jesus went beyond the external act of adultery to address the internal desire: looking at someone with lust is already adultery of the heart. This teaching shocked Jesus' audience and continues to challenge Christians today. The Catholic tradition classifies lust as one of the seven deadly sins because it distorts the God-given gift of sexuality, reducing a person to an object of pleasure. Protestant traditions generally agree, though they may differ on specific applications (such as whether attraction itself is lustful). The Christian answer to lust is not repression but redirection — channeling sexual desire into marriage and cultivating purity of heart through prayer, accountability, and disciplines like fasting.
What You Can Do
- Acknowledge that lust is a struggle — honesty is the first step to freedom.
- Christian: Practice the 'flee' principle (2 Timothy 2:22). Remove triggers — unfollow accounts, install content blockers, avoid compromising situations. Find an accountability partner.
- If lust has become a compulsive pattern or addiction (especially to pornography), seek professional help. This is a recognized struggle that requires support alongside spiritual practice.
- Replace lustful habits with constructive ones: exercise, study, prayer, community service. The most effective way to break a habit is to replace it.

Is attraction the same as lust?
No. All three traditions distinguish between natural attraction (which is normal) and lust (which is disordered desire that reduces a person to an object of pleasure). Noticing that someone is attractive is not sinful. Dwelling on sexual fantasies about them is.
Is lust within marriage a sin?
All three traditions have a generally positive view of sexual desire within marriage. However, some scholars note that even within marriage, treating your spouse purely as an object of gratification without love and respect falls short of the ideal.
Can lust be forgiven?
Absolutely. All three faiths teach that God forgives those who sincerely repent. The key is genuine effort to change, not perfection.
