John Piper offers some excellent counsel regarded how we should view TV and movies and whether we need to immerse ourselves in pop culture in order to contextualize.
I think relevance in preaching hangs very little on watching movies, and I think that much exposure to sensuality, banality, and God-absent entertainment does more to deaden our capacities for joy in Jesus than it does to make us spiritually powerful in the lives of the living dead. Sources of spiritual power—which are what we desperately need—are not in the cinema. You will not want your biographer to write: Prick him and he bleeds movies.
If you want to be relevant, say, for prostitutes, don’t watch a movie with a lot of tumbles in a brothel. Immerse yourself in the gospel, which is tailor-made for prostitutes; then watch Jesus deal with them in the Bible; then go find a prostitute and talk to her. Listen to her, not the movie. Being entertained by sin does not increase compassion for sinners.
There are, perhaps, a few extraordinary men who can watch action-packed, suspenseful, sexually explicit films and come away more godly. But there are not many. And I am certainly not one of them.
I have a high tolerance for violence, high tolerance for bad language, and zero tolerance for nudity. There is a reason for these differences. The violence is make-believe. They don’t really mean those bad words. But that lady is really naked, and I am really watching. And somewhere she has a brokenhearted father.
I’ll put it bluntly. The only nude female body a guy should ever lay his eyes on is his wife’s. The few exceptions include doctors, morticians, and fathers changing diapers. “I have made a covenant with my eyes; how then could I gaze at a virgin?” (Job 31:1). What the eyes see really matters. “Everyone who looks at a woman to desire her has already committed adultery with her in his heart” (Matthew 5:28). Better to gouge your eye than go to hell (verse 29).
