“If we hope to experience transformation, we need to develop a culture in the congregation that encourages people to live in the world for the sake of the world, without being of the world. Gerhard Lohfink, in Jesus and Community, makes a strong case that it has always been God’s intention to work through a visible, tangible, concrete community that lives as a contrast society in the world for the sake of the world. Tim Keller concurs when he says, ‘Christians are truly residents of the city, yet not seeking power over or approval of the dominant culture. Rather, they show the world an alternative way of living and of being a human community.'”
