You always need to organize yourself beyond what you are. If you’re a church of 200 and want to be a church of 500, you need to organize like a church of 500. Otherwise, you won’t get there.
When I became pastor of Mainstreet Church in Walbridge, Ohio, we started at about 220, grew, and began adding staff. I took the staff to larger churches on little field trips. How does it look and feel? How do they structure themselves? We began to tinker. God blessed us and the church grew.
Over half of our growth was new converts. You get people who don’t know anything, and it’s fun. You get a chance to infect them with the real disease.
I covet that for you. Not that you get big; that doesn’t make any difference to me. What makes a difference is that you become effective in what God has called you to do.
