I hope Mrs. Job got a clue from seeing the restoration of her husbands fortunes. Some stories don’t tell us all we would wish to know. I think from the overall context, she got some kind of clue, or she would have been hell on earth for Job and not a fitting part of restored fortunes. She’d be forever berating him about it. But again we have more egalitarian expectations today. In that era prior to the revelation of Christ as explicit savior to the point of undertaking an incarnation, everything centering around Job would make perfect sense. The husband firmly led the family. There wasn’t what we would call Christ consciousness then making a more diffuse social model viable.
God is the forever self-existent, the only One with the true license to say “I am.” I’ve seen it attempted in a skeptical or secular context, in a song that goes “Life isn’t worth a damn, until you can say ‘I am what I am.’” But this collapses too. The singer here should correctly say “I am what the ‘I am’ most positively made me to be.” Or as the bible puts it, “I am what I am by the grace of God.” But we’d have to redo the music to fit that in... ah, the trials of being an artist.
Yes. I've been known to say that while I am in no way perfect except for how Christ made me worthy, I am also a perfect Bob Blaze - I'm as He made me and I'm comfortable in my own skin despite full knowledge of who and what I am. That's the gift of Grace from a truly loving God.
