In Original Sin: Illuminating the Riddle, Henri Blocher proposes to illuminate the riddle the doctrine of original sin presents. The introduction points out that the phenomenon of human evil raises three questions: “First, why is the perception of human evil generally accompanied by feelings of indignation, guilt or shame?” “Secondly, if humans are capable of so much evil, how is it that they also reach heights of heroism, performing admirable deeds of selfless service and devotion to the truth?” “Thirdly,” if the world owes its origin to a holy and wise Creator, “how can we face the apparent contradiction” resulting from “the presence and power of evil in human life?” (11–12).
