“The original sin in a man is like his beard, which, though shaved off today so that a man is very smooth around his mouth, yet grows again by tomorrow morning. As long as a man lives, such growth of the hair and the beard does not stop. But when the shovel beats the ground on his grave, it stops. Just so original sin remains in us and bestirs itself as long as we live, but we must resist it and always cut off its hair.”
–Martin Luther, What Luther Says: An Anthology, comp. Ewald M. Plass (St. Louis: Concordia Publishing House, 1959), entry no. 4176, 1302-3.
