What Shall I Render?

I

For mercies, countless as the sands,
  Which daily I receive
From Jesus my Redeemer’s hands,
  My soul, what canst thou give?

II

Alas! from such a heart as mine
  What can I bring him forth?
My best is stain’d and dyed with sin,
  My all is nothing worth.

III

Yet this acknowledgment I’ll make
  For all he has bestow’d⁠—
Salvation’s sacred cup I’ll take,
  And call upon my God.

IV

The best returns for one like me,
  So wretched and so poor,
Is from his gifts to draw a plea,
  And ask him still for more.

V

I cannot serve him as I ought,
  No works have I to boast;
Yet would I glory in the thought
  That I should owe him most.
