The important part is not the number of people, It is not the parts of the body. The important thing is that God is there!
From what the New Testament teaches, what is important is not the numbers alone. However, it exists so the officers - the pastor, elders, teachers, etc can HELP the members, and the members can help and encourage each other.
So ask yourself, “Is my goal to see how FEW people I can help, and how FEW people can help me to draw closer to Christ?” Because if you are haggling to see how few people you can help and be helped by...there is something VERY wrong!
We may move in a year or so to a small town with no Christian churches. If so...we’ll be a small home church. But if we can find any others Christians there, we’ll join together. The goal will NOT be to see how few can band together!
