Matthew 15:28: That mighty faith on me bestow

That mighty faith on me bestow
Which cannot ask in vain,
Which holds, and will not let Thee go,
Till I my suit obtain;
Till Thou into my soul inspire
The perfect love unknown,
And tell mine infinite desire,
"Whate'er thou wilt, be done!"

But how much greater, O my God,
Thy mercy which the faith bestow'd
On all who now believe.
By violent importunity
To conquer, and extort from Thee
Whate'er Thou hast to give!
