If your church closed, would anyone notice?

From Church Marketing Sucks:

While advertising, street signs and a full garage on a Sunday are great signs of success for a church, they aren’t necessarily indications of a great impact on your community. As Rizzo points out, a billboard may mean that your community knows the name of your church, but does it mean any more than that?

The ultimate test would be this: if your church closed, would anyone notice? Other than the regulars, who would shed a tear for a moment and then go somewhere else? Would the neighbors, local police, community leaders and schools even notice if you disappeared? Now think, what would change that–another advertisement or visiting the sick and staffing an after school club?
