It is not only the rhythm and the lyrics of jarring music that are detrimental. By listening to such music, we also prevent quiet moments that allow us to think clearly and listen to the Spirit. In The Screwtape Letters, a popular Christian novel, a character named Screwtape represents Satan and tries to lead good souls to his cause. Screwtape says, “It is funny how mortals always picture us as putting things into their minds: in reality our best work is done by keeping things out.” In essence, Satan knows that he does not always have to fill our minds with bad thoughts if he can just keep us from focusing on things of the Spirit. “If you listen to music constantly, you may not have the quiet time you need for thinking, feeling, and receiving spiritual guidance” ( For the Strength of Youth, 23).
