this is not exactly the wording but it is the same sentiment
so I thought to post it along with the music from this site:

Is this anywher near what you are looking for?
If not we'll just keep looking
I am not worthy, holy Lord,
That Thou shouldst come to me;
Speak but the word; one gracious word
Can set the sinner free.
I am not worthy; cold and bare
The lodging of my soul;
How canst Thou deign to enter there?
Lord, speak, and make me whole.
I am not worthy; yet, my God,
How can I say Thee nay;
Thee, who didst give Thy flesh and blood
My ransom price to pay?
O come! in this sweet morning hour
Feed me with food divine;
And fill with all Thy love and power
This worthless heart of mine.
