Pastor Peter Haas gives his sermon at Substace Church in the auditorium of Fridley High School. About 650 people watched his sermon about de-stessing you life. The explosion of Gen X and Gen Y churches. This church, called Substance (they tend to have radical names,) is one of the most-successful in the Twin Cities, drawing several hundred worshippers each Sunday. They reach out to young people by cutting back on the ritual of traditional churches. There's also a rock band and multi-media.
