So, why church? The short answer is because the Holy Spirit
formed it to be a colony of heaven in the country of death, the country William Blake named, in his comprehensive reimagining of the spiritual life, "land of Ulro." Church is the core element in the strategy of the Holy Spirit for providing human witness and physical presence to the Jesus-inaugurated kingdom of God in this world. It is not that kingdom complete, but it is a witness to that kingdom.
