amazing grace

they've been playing variations of this song on the radio a lot in the last couple years. it's so easy to not think about the words to the song. it's the one that everyone knows, the one that non-Christians cling to because they need some song at their mother's funeral. it's easy to not pay attention to because it's so familiar. but one line has been jumping out at me lately:

''Twas grace that taught my heart to fear and grace my fears relieved...'

there is so much depth in that simple line.
