One of the [if not the] most moving versions [and thats sayin something after Nina Simone's version] is by Roberta Flack.

It can be found on her first album of Jaz ballads from 69 called 'First Take.'

Her version is retitled: 'I Told Jesus'....and its the Truth!

As this is also the album that 'First Time Ever I Saw Your Face' and other moving ballads are on, I recommend buying the whole album.

Enjoy
