When I was in college I was part of a campus ministry similar to Campus Crusade for Christ. Overall, it was pretty great, but when I got out of college ... nothing. Well, not really nothing. I became part of a good church, but I miss the fellowship and focus of an outwardly-focused organization devoted to bringing Christ to the world.
So I think it would be great if there was a non-denominational organization devoted to 1) Christian growth, 2) mutual support, and 3) local community service - kind of a cross between Campus Crusade and the Lions Club.
Christian Community Service (or whatever it's called) could be a regular dues-paying club that meets once a week for lunch or dinner at a restaurant. There would be teaching, prayer and fellowship, and members would help each other out in times of need. Then, every month or three, CCS would have a community work day. It would arrange with the local parks department to plant flowers at a park, or with the school district to paint classrooms at a local school, or with other local service organizations to do repair work at low income homes. It could raise money to provide scholarships to students from the local high school or to buy playground equipment. The object of these good works - aside from the obvious one of benefitting the community - would be to get Christians out, mingling as Christians with their neighbors and other members of the community, creating friendships with non-Christians, showing love to the community, and hopefully, providing opportunities to share about Christ.
