“Everyone that keeps on looking at a woman so as to have a passion for her has already committed adultery with her in his heart.”​—Matthew 5:28.

For instance, the Bible pointedly states that when a married man “keeps on looking at a woman” to whom he is not married, nurturing a desire to have sex with her, it can lead to adultery. The principle behind this Bible statement would apply to anyone, married or single, who “keeps on looking” at pornographic images with the desire to engage in sexual immorality. Such behavior is clearly offensive to God.
