If I'm not mistaken, the NT describes the church as an assembly of those "called out," specifically because they've been reconciled to God in Jesus. What I observe happening around me is that bigger churches with lots of resources put money into their worship music, and worship service, build a large sanctuary where a big crowd can sit and listen to the up front people, and they attract people from smaller churches that don't have the resources to have a rock concert worship service, or a Disneyworld nursery and children's playland. Church becomes a once-a-week religious entertainment enterprise. And people leave their smaller churches, where they can be involved in work that fits their spiritual gifts to go be entertained once a week. So there is no evangelism and no discipleship.
That can't compete with what kids are getting five days a week, six hours a day in their public school.
