When a congregation undertakes the process of developing a new vision for mission, identity questions are at stake. Preaching possesses the power to form communal identity by exploring biblical images that allow people to imagine their lives differently and by nurturing communal practices distinctive to the Christian faith. It can help to shape a congregation's image of itself as the people of God "sent out" to proclaim the reign of God. In a time when many mainline congregations lament their declining numbers, preaching that refocuses a congregation on its apostolic or missional identity bears the potential to renew its energy and sense of purpose. By following the narrative of one congregation during a visioning process, this thesis project offers guidance for preachers seeking to help a congregation reimagine itself in missional directions. It builds on the work of Craig Satterlee and his emphasis on the importance of holy and active listening for preaching that addresses the psychological dynamics at play during a visioning process. It also explores the model for missional preaching suggested by John Dally that focuses on proclamation of the reign of God, the implications of that reign for God's people, and an invitation to choose the kingdom. When the preacher discerns that the congregation's vision of itself as the instrument of God's reign in the world is lacking, the implication element of Dally's model becomes particularly important. Because people act out of who they are, shaping a congregation's vision of itself becomes fundamental, and should precede the focus on ethics.
