Maintaining these narrow and unconstructive viewpoints simply may be attempts by otherwise well-meaning people to make sense of suffering in the world and to shield themselves against loss (assuming that they have and continue to lead blameless lives). Holding such perspectives, however, is fraught with danger because the day may dawn (heaven forbid) when the doctor hands one of these people a severe diagnosis, a natural disaster visits his neighborhood, or someone in his family suddenly dies out of turn.

Oh, for the patience of Job! The Book of Job in the Bible is one of the most famous Western examples of a search for an answer to the question of why bad things happen to good people. In brief, it’s the story of a righteous man named Job (rhymes with globe) whose faith in God is sorely tried — first by the loss of his wife and children, along with his cattle and servants (both counted as wealth in those days), and later by the loss of his own health. ) openly questions Job’s motivation for remaining upright in the sight of the Lord.

Job finally pipes down and says, “I had heard of Thee by hearsay, but now my eye has seen Thee. That is why I sink down and repent in dust and ashes” (Job 42:4–6). In terms of how to make some sense of seemingly undeserved suffering, the Book of Job argues strongly and consistently against the commonly held notion that bad things only happen to bad people. ” other than the severe view that pain like that suffered by Job is visited on people simply as a test of faith. Better, I think, to adopt Job’s final position wherein instead of being content to hear about the divine through hearsay, you establish a direct relationship with the divine that enables you to see it directly with your own eyes.
