The church isn't a building or even a fixed location, but lets take a look around my area. My Church, (Armstrong Valley Bible Baptist Church) is small, at Christmas service seating is at a premium with 100+ people attending. Normal services there are somewhere around 40 people who support the Church's expenses, building fund, missions, and all other expenses comfortably. We are totally independent and not part of a conference, so we can't be shut down by someone in a building in some city who deems us, ''unprofitable''. Our Church is a simple cinder block building, plain with a nursery, office, kitchen, and fellowship hall/classroom for formal Bible study. Our services are simple and timely, based on Biblical truth and the Gospel of our Savior, Jesus Christ. We have people from several towns attending, one couple drives almost an hour to be there. Our Pastor is full time and lives next to the Church.
Our area is rich in history with most being able to point out where the trading post and British fort was during the French and Indian War, small towns surrounded by prime farm land and mountains. The roads around here were laid out with horse drawn wagons in mind and Church's were numerous, within walking distance of a certain area of farms. Most of these Church's are small, some very small, but they're the ones that have survived, built by local families. Some share a pastor and rotate services between them, some consist of three or more Church's with social functions held at the largest of the three. They, being independent have survived. One Church, a mid size building built in the 1810's survives because the owner, (a cemetery assn.) lets them use it for $1.00 a year with the provision the congregation provides the up-keep and maintenance on it. They, like several other Church's in the area have a pert time pastor who has a full time job elsewhere. They survive and keep the doors open Sunday mornings at least.
The ones who close and get sold and repurposed are usually the newer buildings, and were members of a conference. I don't like conferences, but plainly it isn't the conferences that keep people away from Church. I remember a time when the majority of people attended Church at least on a Sunday morning. That was about all there was to do, most business's were closed, and those who were open were restricted in goods and services they could sell on a Sunday, (good old ''blue laws'').
