O God, Creation’s Secret Force

O God, creation’s secret force,
Thyself unmoved, all motion’s source,
Who from the morn till evening ray
Through all its changes guid’st the day:

Grant us, when this short life is past,
The glorious evening that shall last;
That, by a holy death attained,
Eternal glory may be gained.

O Father, that we ask be done,
Through Jesus Christ, Thine only Son;
Who, with the Holy Ghost and Thee,
Doth live and reign eternally.
