Is­aac Watts, The Psalms of Da­vid 1719. Christ’s king­dom among the Gen­tiles.

Duke Street at­trib­ut­ed to John Hat­ton, 1793 (🔊 pdf nwc).

Perhaps one of the most in­ter­est­ing oc­ca­sions on which this hymn was used was that on which King George, the sa­ble, of the South Sea Is­lands, but of blessed mem­o­ry, gave a new con­sti­tu­tion to his peo­ple, ex­chang­ing a hea­then for a Chri­stian form of gov­ern­ment. Un­der the spread­ing branch­es of the ban­yan trees sat some thou­sand na­tives from Ton­ga, Fi­ji, and Sa­moa, on Whit­sun­day, 1862, as­sem­bled for Di­vine wor­ship.

Fore­most amongst them all sat King George him­self. Around him were seat­ed old chiefs and war­ri­ors who had shared with him the dan­gers and for­tunes of ma­ny a bat­tle—men whose eyes were dim, and whose pow­er­ful frames were bowed down with the weight of years.

But old and young alike re­joiced together in the joys of that day, their faces most of them ra­di­ant with Chris­tian joy, love, and hope. It would be im­pos­si­ble to des­cribe the deep feel­ing man­i­fest­ed when the sol­emn ser­vice be­gan, by the en­tire au­di­ence sing­ing Dr. Watts’ hymn…

Who so much as they could real­ize the full mean­ing of the po­et’s words? For they had been res­cued from the dark­ness of hea­then­ism and can­ni­bal­ism and they were that day met for the first time under a Chris­tian con­st­itu­tion, und­er a Chris­tian king, and with Christ Him­self reigning in the hearts of most of those pre­sent. That was in­deed Christ’s king­dom set up in the earth.

Stevenson, pp. 351–52

Jesus shall reign where’er the sun
Does his successive journeys run;
His kingdom stretch from shore to shore,
Till moons shall wax and wane no more.

Behold the islands with their kings,
And Europe her best tribute brings;
From north to south the princes meet,
To pay their homage at His feet.

There Persia, glorious to behold,
There India shines in eastern gold;
And barbarous nations at His word
Submit, and bow, and own their Lord.

To Him shall endless prayer be made,
And praises throng to crown His head;
His name like sweet perfume shall rise
With every morning sacrifice.

People and realms of every tongue
Dwell on His love with sweetest song;
And infant voices shall proclaim
Their early blessings on His name.

Blessings abound where’er He reigns;
The prisoner leaps to lose his chains;
The weary find eternal rest,
And all the sons of want are blest.

Where He displays His healing power,
Death and the curse are known no more:
In Him the tribes of Adam boast
More blessings than their father lost.

Let every creature rise and bring
Peculiar honors to our king;
Angels descend with songs again,
And earth repeat the loud amen.
