During the waning days of the 1970s Jesus movement, I was 15 and clueless, like most people that age. My church’s youth group had a tradition of traveling each year to a large, outdoor Christian music festival. The event, a self-styled alternative to the Woodstock legacy, offered camping, communal sources of drinking water and food—not to mention outdoor sanitation—and plenty of Jesus served up through “Christian rock” music. Of course, it was really the camp meeting tradition redux. The first evening, with several thousand others and in an atmosphere of drum kits, guitars and evangelical preaching, an “invitation” to faith was issued.
