1 Perpetual source of light and grace!
We hail thy sacred name.
Through ev'ry year's revolving round,
Thy goodness is the same.
2 Inconstant service we repay,
And treach'rous vows renew,
False as the morning's scatt'ring cloud,
And transient as the dew.
3 Low at thy feet our guilt we mourn,
And loud implore thy grace
To bear our feeble footsteps on
In all thy righteous ways.
4 Arm'd with this energy divine,
Our souls shall constant prove,
And with increasing transport press
On to thy courts above.
5 So, by thy pow'r, the morning sun
Pursues his radiant way,
Brightens each moment in his race,
And shines to perfect day.

Perpetual Source of Light and Grace. P. Doddridge. [Inconstancy in Religion lamented.] This hymn is No. 74 in the D. MSS., and undated, but is found between other hymns dated respectively, "Jan. 15, 1737/8," and "Jan. 1, 1738," thus fixing the date as 1738. It was given, without alteration, in Job Orton's posthumous edition of Doddridge's Hymns, &c , 1755, as No. 151, in 6 stanzas of 4 1ines, with the heading "Inconstancy in Religion. Hosea vi. 4," and again, with slight changes, in J. D. Humphreys's edition of the same, 1839, No. 170. It is in a few modern collections, including Martineau's Hymns, &c, 1840 and 1873. In a few collections it begins "Eternal Source of Light and Grace."
