To many people today, the church in the West — and especially in the United States — isn’t working. Whether it’s declining attendance, a society losing interest in Christianity altogether, or an American way of life that seems increasingly post-Christian, something seems wrong. The book of Revelation names this condition in its letter to the Laodiceans: lukewarm. That letter frames Jesus’ call to the church in a way that leaves room for personal response, and it’s where much of my own searching began.
