The Bible does not directly address the subject of voyeurism. Voyeurism is a sexual fetish that involves watching other people engaging in private behaviors such as undressing or participating in sexual activity. Voyeurism also often includes secretly videotaping or photographing the person being watched without his or her knowledge or consent. The voyeur usually observes from a secret vantage point or uses a hidden camera to capture illicit images. Some people consider viewing pornography or even looking at photos of other people on social media sites to be voyeuristic activity, but voyeurism, strictly speaking, is the act of secretly watching or filming people in real life as they undress or engage in sexual activity.
Voyeurism is sinful for at least two reasons: first, it is invasive and disrespectful to the person being watched. The Bible commands people to treat others with respect, justice, and kindness (Micah 6:8; Zechariah 7:9; Galatians 5:22). Voyeurism is a violation of this command—the voyeur treats other people as objects. Second, voyeurism falls under the category of unlawful or immoral sexual behavior. Lust is on the same level, spiritually, with adultery. When we look at another person with “lustful intent,” we have already committed adultery with him or her in our hearts (Matthew 5:28).
Secretly looking at the nakedness of another person (not one’s spouse) is wrong. Stealing of any kind—even stealing someone’s privacy—is sin. Voyeurism is a work of the flesh and a product of sinful desire. The Bible tells us to choose a different path for our lives: “Clothe yourselves with the Lord Jesus Christ, and do not think about how to gratify the desires of the flesh” (Romans 13:14).
