While I agree that tv is detrimental to to a Christian, I wouldnt get rid of it immediately, but make it a goal to work towards. If Christophers wife is unconverted like he seems to indicate, she will not understand and more likely be provoked to leave if Chris starts to tell her what she can and cant do. The ultimate goal is for Chris to save his marriage and win his wife to Christ, which will take much grace and patience. I just dont think laying down the law and expecting her to comply, being unconverted and not of the same convictions, is the right approach at the moment. I think that fervent prayer, and living a blameless Christian life before her is the best option.

"If your wife be unbelieving or carnal, then you also have a duty lying before you, which you are engaged to perforn under a double engagement.

Now to qualify you for a behavior suitable:

One. Labor seriously after a sense of her miserable state, that your heart may yearn towards her soul.

Two. Beware that she take no occasion from any unseemly behavior of yours, to proceed to evil. And here you need to double your diligence, for she lies in your bosom, and therefore is capable of espying the least miscarriage in you.

Three. If she behaves unseemly and unruly, and she is subject to do, being Christless and graceless, then labor to overcome her evil with your goodness, her adversity with your patience and meekness. It is a shame for you, who have another principle, to do as she.

Four. Take every opportunity to convince her. Observe her disposition, and when she is most likely to bear, then speak to her very heart."

One shouldnt make sweeping statements.
