But how can the church announce that God is God, that Jesus is Lord, that the powers of evil, corruption, and death itself have been defeated, and that God’s new world has begun? Doesn’t this seem laughable? Well, it would be if it wasn’t happening. But if a church is … actively involved in seeking justice in the world, both globally and locally, and if it’s cheerfully celebrating God’s good creation and its rescue from corruption in art and music, and if, in addition, its own internal life gives every sign that new creation is indeed happening, generating a new type of community – then suddenly the announcement makes a lot of sense.
