In Christ's role as King, He rules both ____ and in the ____.

The selection 'His kingdom; world' accurately reflects the understanding of Christ's comprehensive authority and rule as King. In the context of Christian theology, this answer emphasizes the dual aspect of Christ's kingship: it acknowledges His reign over the spiritual kingdom, which encompasses the lives of believers and the governance of His will, and the broader world, which includes all of creation.

By ruling "His kingdom," it signifies His leadership in the hearts and lives of His followers, guiding them in faith and obedience. Conversely, ruling "the world" recognizes His sovereignty over all creation, which, despite its current state of disarray due to sin, ultimately acknowledges that Christ maintains supreme authority over it. This dual perspective on Christ's kingship underscores the power and scope of His reign, portraying Him as a sovereign figure with a profound influence in both spiritual and physical realms. This understanding is crucial for believers as it illustrates the comprehensive nature of Christ's authority and the hope of His eventual return to establish His reign in its fullness.
