Human relationships with predators have always been thorny. Predators are the first creatures our kind purposely eradicates. Too often, people feel humans are and should be in control; we are enraged to discover this is not true. And when other creatures share our appetites and kill our livestock (often animals we were raising to kill, ourselves), we call them vandals and murderers. . . Predators are the most persecuted creatures on Earth.
Illness itself can make you angry, enraged, furious, and it made me angry, enraged, and furious. I don't think it brought me to God at all. It depends how you deal with it. And I think that, at its best, three little words that always have to be applied to religion, religion can help you to deal with that.
