I found the lyrics to this song this morning.  I tried unsuccessfully to find the song to download from various "places."  I so wish I could get my hand on it.  I'd love to hear it.  But for now the lyrics will have to do.

The wond'rous gift that Jesus offers me if
I but lift my heart desiresly
The only ways the venture of my face
To prove the miracle of his redeeming grace

I stumble over such simplicity 
Lord I do believe help Thou my unbelief
Must I refuse the gift until I understand
It's mine the moment that I let him take my hand
Lord will within my heart the will to obey
Break my stubborn will that stands in the way
I would know the miracle of sweet relief
Lord I do believe help Thou my unbelief
Lord I do believe I do believe
