R. C. Sproul has written a beautiful hymn that warrants a look or two:
Fallen race in Eden fair, exposed and full of shame. Fled we naked from Thy sight, far from Thy holy name.
Sent from the garden to the east, outside of Eden's gate, Banished there from Thy pure light were Adam and his mate.
Scarlet souls are now like snow by Thy atoning grace. Crimson hearts become like wool for Adam's fallen race.
No work of ours is good enough for evil to atone. Your merit, Lord, is all we have. It saves and it alone.
