"Why were hymns, and why have hymns been, so important for all evangelical movements from the eighteenth century through the present? Historically considered, it is possible to interpret the role of hymnody for evangelicals as just one more particular episode illustrating humanity's deep bond to and with music. Movie goers who are conscious of connections between the scores they hear and what they are watching on the screen know that Martin Luther once caught it exactly: "For whether you wish to comfort the sad, to terrify the happy, to encourage the despairing, to humble the proud, to calm the passionate or to appease those full of hate ... what more effective means than music could you find?" We are what we sing, the music we listen to regularly, the music we instinctively like, the music that brings tears to our eyes or a charge of energy to our spirits, the music that expresses our deepest longings and strongest loyalties."
