The ultimate goal? Christ 'delivers the kingdom to God the Father.' This sounds like a transfer of power, but what's really happening?
This isn't about Christ handing over something he no longer has or wants. It's the completion of his mediatorial reign, bringing everything back into perfect harmony with the Father.
Unified Rule
Throughout his reign, Christ has been acting as God's representative, bringing all things under His will. When he delivers the kingdom, it signifies the perfect and final establishment of God's rule through Christ, in which Father, Son, and Spirit are in complete, unhindered unity with all creation.
The Father's Ultimate Authority
It highlights that Christ's reign is ultimately for the Father's glory. He comes to fulfill His Father's plan entirely. This isn't Christ stepping down, but rather the culmination of His mission, where His unique role as King and mediator is completed, and the fullness of God's eternal reign is manifest.
