I don't think I got all the lyrics transcribed correctly so please correct:
One day all they'll have is a faded photograph
to remind them of the man I used to be
There'll be things that they recall but I pray above it all
the love of Jesus and what remains of me
Chorus:
It won't matter what I've earned or who I've known
It will all be forgotten when I'm gone
but If I can all but leave just one memory
I pray the love of Jesus is what remains of me
One day if they trace every step I took by faith
may it lead them to the cross of Calvary
I just want to leave behind a legacy so they can find
the love of Jesus and what remains of me
