Does the Bible say anything about pornography?
Pornography is material designed to generate lust—to allow one to look at others lustfully. Jesus equates this directly with the sin of adultery.
In the Sermon on the Mount, he declares: “You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman lustfully has already committed adultery with her in his heart” (Mt 5:27-28).
Then he immediately says: “If your right eye causes you to sin, pluck it out and throw it away; it is better that you lose one of your members than that your whole body be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away; it is better that you lose one of your members than that your whole body go into hell” (Mt 5:29-30).
Jesus is not telling us to literally pluck out our eyes or cut off our hands, but he uses this vivid language to stress that we must do whatever it takes to deal with sexual sin.
