Phil Calloway, while on his back recovering from an ATV accident, exposed himself to too much TV, and he recognized a particular problem with that:
The trouble with TV is that it is filled with whatsoever things are of bad report. Who would keep a friend around who is rude, loud, and uncouth? One who never listens and begs you to lust and covet?
To that, you might add also a few comments from John Piper on television (from several different sermons), including this one from “Advice to Pastors: How to Help Your People Be More Satisfied in God“:
Help your people to turn off the television. Few things in our culture are more spiritually numbing than the television. Even the so-called “good” shows are by and large banal and low-minded and anything but cultivating of a rich, deep capacity to enjoy God. And when you add to that the barrage of suggestive advertisements that accompany virtually every program, I do not wonder why so many of our professing Christians are spiritually incapable of experiencing high thoughts and deep emotions.
