Participants in the kingdom of the world trust the power of the sword to control behavior; participants of the kingdom of God trust the power of self-sacrificial love to transform hearts. The kingdom of the world is concerned with preserving law and order by force; the kingdom of God is concerned with establishing the rule of God through love. The kingdom of the world is centrally concerned with what people do; the kingdom of God is centrally concerned with how people are and what they can become. The kingdom of the world is characterized by judgment; the kingdom of God is characterized by outrageous, even scandalous, grace.
