What about pornography?

Question 12023

The sin of pornography is the one I am asked about most often in private and preached about least often in public, and that imbalance tells you something. It is in our congregations. It is among our leaders. It is not a marginal problem affecting a few unusually weak people, and pretending otherwise leaves the people trapped in it convinced they are alone.

So I want to be direct without being crude, and hopeful without being glib. This is serious, and there is a way out. Both of those things are true, and a believer stuck in it needs to hear them in that order.

What Jesus said about the eyes and the heart

Jesus locates sexual sin in the heart before it ever reaches the body. “Everyone who looks at a woman with lustful intent has already committed adultery with her in his heart” (Matthew 5:28). That is not hyperbole for effect. It is a statement about where sin actually lives.

Which means pornography is not a lesser category of offence because nobody is touched. In the terms Jesus uses, it is adultery conducted privately and repeatedly. The Greek behind lustful intent, epithumeo, describes a settled craving rather than a passing glance, and that distinction matters. Temptation is not the sin. Cultivating it is.

Job made a covenant with his eyes not to gaze (Job 31:1), which tells us that this battle was fought long before anyone had a phone. The technology has changed the scale beyond recognition. The problem it feeds is as old as the human heart.

What it does to the person watching

Pornography trains the mind to treat a person as a commodity. That is not a moralistic flourish; it is a description of the transaction. An image is consumed for private gratification, and the human being in it is functionally irrelevant. Repeat that ten thousand times and something is being formed.

It also rewires desire. The mechanism is well documented: escalation, tolerance, and a growing gap between the manufactured stimulus and ordinary human intimacy. Many men discover this only when they find that real relationship has become unsatisfying by comparison, which is precisely the opposite of what they were promised.

And it isolates. Shame drives it underground, and secrecy makes it stronger. “Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy” (Proverbs 28:13). The sin of pornography thrives in exactly the conditions that shame produces.

The people in the images

We should also say plainly what is often ignored. The people on the screen are made in the image of God. Many are trafficked, coerced, drugged or exploited, and the industry has a documented record on this that should trouble anyone who takes Proverbs 31:8-9 seriously.

Even where consent is genuine, viewing sustains an industry that consumes people. James says we curse “people who are made in the likeness of God” with the same mouth we use to bless (James 3:9). The principle applies to what we look at as much as to what we say.

I raise this because the argument that pornography is a victimless private matter falls apart the moment you look at it honestly. There is a supply chain, and it runs through human beings.

What it does to a marriage

Spouses who discover this describe it in the language of betrayal, and they are right to. Something that belonged exclusively within the marriage has been given elsewhere, repeatedly and deliberately. The fact that no other person was physically present does not soften the blow, and it is unkind to suggest it should.

There is also the matter of the deception that accompanies it. Almost always there has been lying, and often for years. Rebuilding trust after that takes longer than the person who confessed expects, and impatience about it is one of the quickest ways to make things worse.

For couples in that place, my counsel is to get help early rather than trying to manage it privately. This is not a failure of faith. It is the sort of wound that heals better with a wise third party involved, and there is no shame in that.

Why willpower fails against the sin of pornography

Most believers try to fight the sin of pornography by resolving harder. They repent sincerely, promise God it will not happen again, and are back within a fortnight. Then despair sets in, and despair is far more dangerous than the original struggle.

Paul explains why this happens. Rules “are of no value in stopping the indulgence of the flesh” (Colossians 2:23). The flesh cannot be reformed by the flesh. Something else has to be at work, and Paul names it: “if by the Spirit you put to death the deeds of the body, you will live” (Romans 8:13).

That is not passivity. Putting to death is active and violent language. But it is action performed in dependence rather than in self-reliance, and the difference between those two is the difference between exhaustion and progress.

Practical steps that actually help

Grace does not exclude practical measures; it fuels them. Jesus spoke about cutting off a hand and tearing out an eye (Matthew 5:29-30), which is a call to drastic, concrete action against whatever provides access.

So take away the means. Filtering and accountability software on every device, configured by somebody else. No devices in private at night. If a particular platform or app is the entry point, delete it and do not negotiate with yourself about it. The person who keeps one door unlocked is not yet serious.

Then bring in a person. Not a vague accountability arrangement that asks how things are going, but a specific believer who knows the whole history and asks direct questions on a fixed day. “Confess your sins to one another and pray for one another, that you may be healed” (James 5:16). Healing is attached to confession in that verse, and I have watched it happen exactly that way.

Renewing the mind for the long term

Removing access buys time. It does not change appetite. The deeper work is the renewal of the mind (Romans 12:2), the slow replacement of a worldly account of sex with a biblical one, and of a starving inner life with a fed one.

This is why I press people towards Scripture, prayer and the ordinary life of the church rather than towards yet another technique. Pornography usually flourishes in a soul that is bored, lonely, exhausted or unfed, and those conditions have to be addressed or the appetite simply finds another route.

Expect setbacks without excusing them. Sanctification is not a straight line, and a fall is not a reason to abandon the fight. “The righteous falls seven times and rises again” (Proverbs 24:16). The measure of progress is the direction of travel over years, not the absence of any bad week.

A word to women, and to parents

Two groups get overlooked in this conversation. The first is women. The assumption that pornography is a male problem leaves Christian women who struggle with it doubly isolated, since they carry both the sin and the belief that their experience is unheard of. It is not unheard of. It is simply unspoken, and that silence is cruel.

The second is parents. The average age of first exposure is far younger than most parents assume, and it is usually accidental. Children are encountering material that adults of my generation would have had to seek out deliberately, and they are encountering it on devices we handed them.

So talk to your children earlier than feels comfortable, and talk more than once. Explain what they may see, why it is not what God made sex to be, and above all that they will not be in trouble for telling you. A child who believes he will be punished for what appeared on his screen will simply keep it to himself, and secrecy is where the sin of pornography does its worst work. “Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord” (Ephesians 6:4) includes preparing them for a world we did not grow up in.

So, now what?

The sin of pornography is not a minor indulgence or a private matter without consequences. It dehumanises the people in it, enslaves the person watching, damages marriages and thrives on secrecy. The church has to be able to say that plainly, without embarrassment and without condemnation.

And it has to say the other half just as plainly. No believer is beyond the reach of the Spirit’s work, and no pattern is too entrenched for God to break. Freedom begins where secrecy ends. If this is you, tell one trusted believer this week, before the resolve fades. You may also want to read what the Bible says about lust, what sexual purity involves and how habitual and addictive sin works.

“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 honour.”
