The metaphor is rich and deep with many layers. The world thinks poorly of Christ but his are the values of divinity--he is precious to God. God's enterprise begins with Christ, is founded on him, and extends from him, throughout the world in those who 'come to him.' Christ and his people are the 'house' God builds for himself in the world, to be in. As living stones we are material that God is using to bless others.
