As o'er each continent and islandThe dawn leads on, another day,The voice of prayer is never silent,Nor dies the strain of praise away.
When we've been here ten thousand years,Bright shining as the sun,We've no less days to sing thy praisethan when we first begun.
Amazing graceJohn Newton (1725-1807)

The day thou gavest, Lord, is ended,The darkness falls at they behest;To thee our morning hymns ascended,Thy praise shall sanctify our rest.
The day thou gavest, Lord, is endedJohn Ellerton (1829-93)
The day thou gavest, Lord, is ended,The darkness falls at they behest;To thee our morning hymns ascended,Thy praise shall sanctify our rest.
We thank thee that thy church unsleeping,While earth rolls onwards into light,Through all the world her watch is keeping,And rests not now by day or night.
As o'er each continent and islandThe dawn leads on, another day,The voice of prayer is never silent,Nor dies the strain of praise away.
The sun that bids us rest is wakingOur brethren 'neath the western sky,And hour by hour fresh lips are makingThy wondrous doings heard on high.
So be it, Lord; thy throne shall never,Like earth's proud empires, pass away,Thy kingdom stands, and grows for ever,Till all they creatures own thy sway.
