The answer is: His birth

Job 3:1 - Job wished he had never been born

In the Book of Job, right off the bat in chapter 3, we witness Job in a deep and heartfelt lament about the very act of his birth. It's gut-wrenching and utterly human to see someone with such vast personal anguish grapple with the seeming futility of existence itself. Job, who had everything—a wealthy life, a loving family, and good health—finds himself within the throes of unimaginable suffering following a series of catastrophic events that snatch away his fortune, family, and health.

His lament raises profound questions about the nature of suffering and existence that resonate throughout literature and philosophy. Did you know that Job's story has echoed in various cultures throughout history? His plight highlights an age-old theme: Why do bad things happen to good people? In a way, Job acts as a template for all who question life's injustices, offering an exploration that many relate to.

Additionally, the traditional Jewish perspective identifies Job’s suffering as occurring because he was a righteous man. Yet strangely, his relations with God and the big ‘Why?’ of it all specifically reject other cultural assertions that assume wrongdoing leads to wrong outcomes. It's a refreshing reminder of the complexity of real human experiences versus neat theological boxes—all encapsulated in passionate speeches, poetic verses, and deep existential questioning that resonate beyond time and culture. It’s in this passionately vulnerable exploration Job reminds us how crying out about our burdens is, in itself, a well-founded part of the human experience.
