John Gill Bible Commentary

God reigneth over the Heathen,.... He reigned over Israel under the former dispensation, and now he reigns over the Gentiles under the Gospel dispensation; as appears by the numerous instances of conversion among them in the first ages of Christianity; and by the many churches that were planted by the means of the apostles; and by the destruction of the Roman Pagan empire under the sixth seal, Rev 6:12; and which will still more appear by the destruction of Rome Papal, when all the Heathens shall perish out of the land; and by the fulness and forces of the Gentiles being brought into a submission to him; all which are reasons to sing praises to him; God sitteth upon the throne of his holiness; or his holy throne, which is heaven; on the right hand of the throne of the Majesty in the heavens; on his Father's throne; having done his work on earth he is received up into heaven, and is set down on a throne at the right hand of God, an honour which none of the angels have: he has ceased from his work and entered into his rest, and sits and sees of the travail of his soul; all which is matter of joy to his people, and a reason why they should sing praises; and the rather, since they are set down with him in heavenly places: or this may be understood of his sitting on the throne of judgment to judge the world in righteousness at the last day, it following upon his reign over the Gentiles; though the other sense best agrees with his immediate ascension to heaven.
