Ted Turnau explains why and how Christians should engage popular culture :
Popular culture works not by blurting out a message, but through appealing to the imagination. A television show does not simply convey a message, such as Life is meaningless, so have all the fun you can while you can. Rather, it tells a story in which someone discovers the truth of that message; it tells it in a style that underlines that message, and it invites us along for the journey. Popular culture works indirectly, suggestively, not like a slogan at a political rally, but like a poem or a song. It draws you in and gets under your skin. Therefore, you must be intentional in your approach to popular culture so that you understand its effects on the imagination (including the imaginations of your friends and neighbours).
