I'm assuming you meant My Past Has Passed from the album The Past is Past
The Past is Past - The KingsmensÂ

The guilt and the shame of all I had done
continually weighed me down
The shackles were heavy and my spirit weary
there was no peace to be found
I wondered in darkness, searching for light
a traveler who'd lost his vision
Then I called on His name. My sin it was payed.
Now I'm free; my burdens lifted
Chorus
My past has passed; my sins forgiven
His unending love washed my guilt away
I'm a child by adoption, an heir to His throne
Praise the Lord my past has gone
I know there are days life seems like a mountain
and not sure the climb can be made
The cliff steep and rugged as you endlessly struggle
with memories of past choices made
Just know this for certain, the moment you asked,
forgiveness was given right then
When Satan declares the sin's still there
then God asks the question "What sin?"
