When all is said and done, the church-growth movement will stand or fall by one question: In implementing its vision of church growth, is the church of Christ primarily guided and shaped by its own character and calling—or by considerations and circumstances alien to itself? Or, to put the question differently, is the church of Christ a social reality truly shaped by a theological cause, namely the Word and Spirit of God?
Behind this question lies the fact that the church of God only “lets God be God,” and is only the church, and is free when she lives and thrives finally by God’s truths and God’s resources. If the church makes anything else the principle of her existence, Christians risk living unauthorized lives of faith, exercising unauthorized ministries, and proclaiming an unauthorized Gospel.
Yet, that is precisely the temptation modernity gives to us—the very brilliance and power of its tools and insights mean that eventually, there is no need to let God be God. In fact, there is no need for God at all in order to achieve measurable success. Modernity creates the illusion that when God commanded us not to live by bread alone but by every word that comes from His mouth, He was not aware of the twentieth century. The very success of modernity undercuts the authority and driving power of faith until religion becomes merely religious rhetoric, or organizational growth without spiritual reality.
