John Piper gives some excellent thoughts on why he doesn’t have a TV. This is not a rule he enforces on others, nor is he asking everyone to ditch their TV. But all of us should consider the important warnings he offers regarding the effect tv and movies can have on our souls. Read the entire article, but I’ve provided an excerpt from the meatiest part below.

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).

Brothers, that is serious. Really serious. Jesus is violent about this. What we do with our eyes can damn us. One reason is that it is virtually impossible to transition from being entertained by nudity to an act of “beholding the glory of the Lord.” But this means the entire Christian life is threatened by the deadening effects of sexual titillation.

All Christ-exalting transformation comes from “beholding the glory of Christ.” “Beholding the glory of the Lord, [we] are being transformed into the same image from one degree of glory to another” (2 Corinthians 3:18). Whatever dulls the eyes of our mind from seeing Christ powerfully and purely is destroying us. There is not one man in a thousand whose spiritual eyes are more readily moved by the beauty of Christ because he has just seen a bare breast with his buddies.

But leave sex aside (as if that were possible for fifteen minutes on TV). It’s the unremitting triviality that makes television so deadly. What we desperately need is help to enlarge our capacities to be moved by the immeasurable glories of Christ. Television takes us almost constantly in the opposite direction, lowering, shrinking, and deadening our capacities for worshiping Christ.

One more smaller concern with TV (besides its addictive tendencies, trivialization of life, and deadening effects): It takes time. I have so many things I want to accomplish in this one short life. Don’t waste your life is not a catchphrase for me; it’s a cliff I walk beside every day with trembling.

TV consumes more and more time for those who get used to watching it. You start to feel like it belongs. You wonder how you could get along without it. I am jealous for my evenings. There are so many things in life I want to accomplish. I simply could not do what I do if I watched television.
