Music is universal. It can inspire, soothe, and challenge. It can speak to the soul. In many ways life is very much like music. Rob Bell believes that all human beings can hear God's song and are either in tune or out of tune with his beautiful song.

He states in his Nooma DVD series Rhythm, "The song is playing all around us all the time, the song is playing everywhere, it's written on our hearts, and everybody is playing the song. See, the question isn't whether or not you're playing a song, the question is 'Are you in tune?'"
