Sweet tenants of this grove!
Who sing without design,
A song of artless love,
In unison with mine:
These echoing shades return
Full many a note of ours,
That wise ones cannot learn,
With all their boasted powers.
O thou! whose sacred charms
These hearts so seldom love,
Although thy beauty warms
And blesses all above;
How slow are human things,
To choose their happiest lot!
All–glorious King of kings,
Say why we love thee not?
This heart, that cannot rest,
Shall thine for ever prove;
Though bleeding and distressed,
Yet joyful in thy love:
'Tis happy though it breaks
Beneath thy chastening hand;
And speechless, yet it speaks,
What thou canst understand.
William Cowper
