It’s good to return periodically to Dallas Willard’s perspective on church growth:
The gospel of King Jesus and of his kingdom-now is indeed “the power of God that brings salvation/deliverance.” To prove this, just preach, teach, and manifest the good news of life now, for you and everyone, in the kingdom of the heavens with Jesus—your whole life. Study the Gospels to see how Jesus did it, and then do it in the manner he did it. You don’t need a program, a budget, or any special qualifications to do this. Just understand it in the biblical form and do it. Scot McKnight gives you the key.
Forward to The King Jesus Gospel – Dallas Willard
We must, of course, settle it in our minds that there will always be difficulties in the local setting when one becomes serious about discipleship to Jesus and an associated curriculum. But God is always there for those who serve him, no matter what; and we can “count it all joy”—really—and expect the manifest grace of God to be active in our midst. Although I have not been a pastor for many years, I have always continued to teach quite regularly in churches and churchlike settings. The appeal and power of Jesus’ call to the kingdom and discipleship is great, and people generally, of every type and background, will respond favorably if that call is only presented with directness, generosity of spirit, intelligence, and love, trusting God alone for the outcome. We may not soon have bigger crowds around us—and in fact they may for a while even get smaller—but we will soon have bigger Christians for sure. This is what I call “church growth for those who hate it.” And bigger crowds are sure to follow, for the simple reason that human beings desperately need what we bring to them, the word and reality of The Kingdom Among Us.
