"When Christians catch a vision of the Kingdom of God, their sight shifts to the poor, the orphan, the widow, the refugee, the wretched of the earth, to God's future—to the concerns of justice, mercy and truth. Church people think about how to get people into the church; Kingdom people think about how to get the church into the world. Church people worry that the world might change the church; Kingdom people work to see the church change the world."
