Analysis of Grace

My stock lies dead and no increase
Doth my dull husbandry improve:
O let thy graces without cease
Drop from above!

If still the sun should hide his face,
Thy house would but a dungeon prove,
Thy works, night's captives:  O let grace
Drop from above!

The dew doth ev'ry morning fall;
And shall the dew outstrip thy dove?
The dew, for which grass cannot call,
Drop from above.

Death is still working like a mole,
And digs my grave at each remove:
Let grace work too, and on my soul
Drop from above.

Sin is still hammering my heart
Unto a hardness, void of love:
Let suppling grace, to cross his art,
Drop from above.

O come! for thou dost know the way.
Or if to me thou wilt not move,
Remove me, where I need not say,
'Drop from above.'
