And none of this is really a secret. For instance, here are more than 30 pages of emails from Kerry Morrison to various coreligionists extolling the virtues of Christian love for one’s City, praying for one’s City, serving one’s City as a “Christ Follower,” and whatnot. And there’s a long and vital tradition of this kind of thing in Christianity, to be sure. E.g. compare Paul’s letter to the Hebrews 11:9-10 on how Abraham’s faith led him to leave his home and live like a stranger for the sake of finding the City of God:
By faith he made his home in the promised land like a stranger in a foreign country; he lived in tents, as did Isaac and Jacob, who were heirs with him of the same promise. For he was looking forward to the city with foundations, whose architect and builder is God.
