All you need. Nothing you don't.
Traditional churches have taken note of the growing desire for more simple ways to worship.
“Every large church I know is looking for ways to get small, to provide intimacy that may be missing,” says Kevin DeYoung, senior pastor at the 500-member University Reformed Church in East Lansing, Mich., and co-author of Why We Love the Church: In Praise of Institutions and Organized Religion.
