How exactly men took this discovery of their own impending deaths we shall consider in a moment. But we note first the special place of Noah. Noah, born in 1056, is the first man born into the world after Adam dies. Noah is therefore the first man who could have no direct contact with the first man and, therefore, with a living memory of the Garden of Eden and its prospect of immortal life. More important, Noah is the first man who enters a world in which death is already present, the first man who grows up knowing about death, know that he must die. For Noah unlike for his predecessors, mortality is a received part of the human condition: thus, Noah (not Adam or Cain) is the prototype of self-consciously mortal man. Fittingly, the name that Noah carries, received from his father, Lamech, means both “comfort” and “lament,” a perfect name for new life seen in the light of inevitable death. These facts may explain, in part, why Noah would, uniquely, later find grace in the eyes of the Lord.
