John Piper:
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.
Read the whole thing, which includes an apology for sinfully snapping at a questioner at the Advance conference, and more thoughts on TV, movies, and especially nudity.
