Psalms 97:1 - Joseph Benson’s Commentary on the Old and New Testaments

The Lord reigneth He that made the world, governs it; he that called the universe into existence, upholds and presides over it; and he rules, judges, and rewards, or punishes his intelligent, free, and immortal creatures, whether men or angels. The Lord Jesus reigns; the providential kingdom is interwoven with the mediatorial, and the administration of both is in the hand of Christ; who is therefore both head of the church, and head over all things to the church: see on Psalms 93:1; Psalms 96:10. Let the earth rejoice The inhabitants of the world everywhere; for hereby they are honoured and benefited unspeakably: they are blessed with sure protection, a wise and equitable government, holy, just, and salutary laws, and an ample provision for the supply of all their wants. Let the multitude of isles be glad thereof Not only let the people of Israel rejoice in him, as king of the Jews, and the daughter of Zion, as her king, but let all the earth rejoice in his exaltation; for the kingdoms of the world shall, sooner or later, become his kingdoms. There is enough in Christ for the multitude of isles to rejoice in; for, though millions have been made happy in him, yet still there is room.
