That is what true faithful living is - how you use your time . We are fed by the values of the god of this age, and of his troops, all the time. He pushes them at us through the media. On TV you watch murder, illicit sex, lust, stealing, violence, materialism, false religion, occult things, many more such and worse things. Same with radio and paper media.
Commercials are full of deception, sex, lust, wrong values and so on, same there.
Actually, often even the words you use and the way you speak and even think , are more a product of the TV and commercials than of any other single source. You have all those TV sets in the different rooms, they are on from breakfast to your going to bed. Some have them even in the bathroom. That goes even for the way of one's thinking . Commercials are superficial.
