Job curses his own life, in violent and extravagant terms. All that a man would normally wish for his life, he now deliberately wishes the opposite.
‘It seems here that he would pervert the whole order of nature. But in this we see how our passions boil within us. It is true that if men could mourn without excess in their afflictions, it would not be condemned. Why so? Because the Lord Jesus Christ was not affectionless, or without affection. Yes, we see that when he endured any grief, he felt it, he sighed at it, and he was sad for it, and yet for all that, he was the unspotted Lamb of God, so that there was nothing in him that could be blamed. How is it then that he had heaviness in him? Save only that his sorrowing was moderated as was convenient, and was not wicked or sinful in itself. But all our passions are wicked, because they are wrapped in some stubbornness against God, or in some mistrust, or in some other failing of the flesh … If we compare Job with those that blaspheme God with open mouth, I ask you, how worthy are such men to be condemned? For Job having served God all the time of his life, is nevertheless set here as it were upon the scaffold by the Spirit of God, so that men might by him perceive their own wretchedness and humble themselves and understand that, when the grace of God tells them, they are in danger of casting themselves into hell if they are not held back. Seeing that God’s will was to exercise Job in such a way, as to let him become a gazing stock and to make him serve as an example and instruction to others, what shall become of those that blaspheme God without cause?’ (Calvin – English updated).
