A tweet affirmed that the goal of missions is to plant churches that plant other churches. I have no beef with the general idea. The gospel ought to spread to every place. But the wording doesn't get much support from the NT. The church is a product of proclaiming the gospel. The emphasis is on the latter. The tweet puts forth a humanly based activity. It sets aside the activity of God. It probably reflects denominational bias. When the gospel is preached in its fullness and truth, God adds the converts to his church and they begin to meet together. Quite simple, is it not?
