Worship ... fits right into the consumerism that so characterizes American religious life. Church-shopping has become common. A believer will compare First Presbyterian, St. John's Lutheran, Epiphany Episcopal, Brookwood Methodist, and Bethany Baptist for the "best buy." The church plant, programs, and personnel are carefully scrutinized, but the bottom line is, "How did it feel?" Worship must be sensational. "Start with an earthquake and work up from that," advised one professor of homiletics. "Be sure you have the four prerequisites of a successful church," urged another; "upbeat music, adequate parking, a warm welcome, and a dynamite sermon." The slogan is, "Try it, you'll like it."
