John Gill expounds on the kingly office of Christ, emphasizing that He reigns both by nature as God and by office as Mediator. Christ's kingdom is universal, encompassing all creation, and He exercises authority over both good and evil beings. His reign is characterized by righteousness, peace, and the gradual expansion of His spiritual kingdom, which is established through the ministry of the Word and the work of the Holy Spirit in the hearts of believers. Gill highlights that Christ's kingdom is everlasting, with no end, and will ultimately culminate in His glorious reign over all creation.
