Quoting Christopher Wright:
If a piece of meat goes rotten, it’s no use blaming the meat. That’s what happens when meat is left out on its own. The question to ask is, Where is the salt?
If a house gets dark at night, it’s no use blaming the house. That’s what happens when the sun goes down. The question to ask is, Where is the light?
If society becomes more corrupt and dark, it’s no use blaming society. That’s what fallen human nature does, left unchecked and unchallenged. The question to ask is, Where are the Christians?
Where are the saints who will actually live as saints — God’s different people, God’s counterculture — in the public square? Where are those who see their mission as God’s people to live and work and witness in the marketplace, and pay the cost of doing so? (The Mission of God’s People, p. 236)
