If I were Job, then I suppose I would say, "Thank you, Sir, can I have another!"
Happily, I'm not Job.
Remaining faithful through adversity is a display of loyalty, and many of us exhibit this in our lives (faithful to wives, faithful to corporations, faithful to our own ideals, et al ad inifinitum). Sometimes it's even justified or valued.
But when someone in power makes a mockery of that loyalty, that rather changes the picture.
Since I can't conceive that God guides football players to success nor to ruin, I can't accept that God is the arbitrary sadist shown in Job, either.
