I recently went to an evangelical church with my son... he wanted to go to sunday school and this church had a really organized, well-run one. Well we walked into the lobby and immediately we were approached, ushered into a room, and asked to wait. About 2 minutes later a very polished woman appeared, took us on a deluxe tour of the facility, gave us a "welcome package" which included a Jesus movie... the process for enrolling my son in the sunday school took about 5 minutes. The whole time everyone acted so ooey-gooey sweet it was unreal. Trust me, these people have studied this and made it into as streamlined and effective a process as they can. They've turned it into a science.
