My Heart is Full

My heart is full,
My joy complete,
My life is rich,
My prayers are sweet.
And I know how this came to be:
It's all of you, and none of me.

So what's to be done
With a blessed life like mine?
Lord, use it up,
Like oil and wine.
Then touch me again, my cup overflow,
And grant me once more
Your favor to know.
