The Bible does not directly mention pornography, cybersex, or similar activities. However, the Bible is very clear on how God feels about actions that promote sex outside marriage or a distorted view of sex. Consider these Bible verses:

• “Deaden, therefore, your body members that are upon the earth as respects fornication, uncleanness, sexual appetite.” (Colossians 3:5) Rather than deadening wrong desires, viewing pornography inflames them. It makes one unclean, or dirty, in God’s eyes.

• “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) Images of immoral sexual practices trigger wrong thoughts that lead to wrong actions.

• “Let fornication and uncleanness of every sort or greediness not even be mentioned among you.” (Ephesians 5:3) We shouldn’t for pleasure even mention immoral sex, much less watch or read about it.

• “The works of the flesh are manifest, and they are fornication, uncleanness, . . . and things like these. As to these things I am forewarning you, the same way as I did forewarn you, that those who practice such things will not inherit God’s kingdom.” (Galatians 5:​19-​21) God views those who use pornography or engage in cybersex, phone sex, or sexting as being unclean, morally contaminated. If we were to make a practice of such things, we could completely lose God’s favor.
