“Christians go into the world as witnesses of the kingdom (Acts 1:6-8). To spread the kingdom of God is more than simply winning people to Christ. It is also working for the healing of persons, families, relationships, and nations; it is doing deeds of mercy and seeking justice. It is reordering lives and relationships and institutions and communities according to God’s authority to bring in the blessedness of the kingdom.”
