Here is a post from a 'twenty-something ministering to twenty-somethings': Newsflash! The Key to the 20-Somethings is Not Musical Style.
Fellow Boomers, if you want pop music praise songs in church, great. But admit that it's for you and don't pretend that it's the only thing that will get your kids into church.
To me, the post presents the biggest problem of all for elderly congregations that want to attract younger people. People want to stick to their own age groups. It takes young people to attract young people. You need a core group of active 20-somethings to attract 20-somethings.
