I’ve seen this and it’s sad to think of the members who are not mobilized, the gap that other members step into, and the people that will hear and believe the gospel if churches would just think outside of their local church and see their local church as Christ’s and not theirs.
From R. Scott Clark:
Recently I became aware of a situation where a congregation, with the necessary resources, refused an opportunity to extend Christ’s kingdom through planting a church. Why did they refuse? Because they were afraid of losing members to the church plant. They seem to conceive of the church as a zero sum game, as if somehow, if members left “their” congregation that “their” church would be diminished. Their stance toward the church proposal seems to have been: let the outsiders come to us. I’ve seen this phenomenon more than once. The underlying assumption seems to be, “the church exists for us.”
