"In other words, throughout the biblical narrative God calls his people to embody an alternative vision of community life: the people of God live a community ethic that stands at odds with the unbelieving peoples around them. Through being a "peculiar people," the people of God can bear witness to the will of God, as well as bring about transformative change for the cities in which they dwell. Only by being what God has called his people to be can his people really bring about good for the cities in which they dwell."
