Broadly speaking, the kingdom of God is the rule of an eternal, sovereign God over all the universe. Several passages of Scripture show that God is the undeniable Monarch of all creation: “The LORD has established his throne in heaven, and his kingdom rules over all” (Psalm 103:19). And, as King Nebuchadnezzar declared, “His kingdom is an eternal kingdom” (Daniel 4:3). Every authority that exists has been established by God (Romans 13:1). So, in one sense, the kingdom of God incorporates everything that is.
