“Our God,” a praise hymn by Matt Redman, is the most popular song sung in American churches, according to a chart that tracks such matters. Approaching the top ten list is a retro hymn, “In Christ Alone,” cowritten by Keith Getty. Getty represents a newer group of songwriters who try to get more content into their songs than the usual praise songs. Getty believes hymns should be singable without a band and should say something bold. “I think it’s to the church’s poverty that the average worship song now has so few words. . . . It is so focused on several commercial aspects of God, like the fact that he loves our praises,” Getty says (NPR, July 8).
