What do you Job know that we also do not know? What superior method of obtaining knowledge is available to you that we do not share? Of course the implied answer is, none. All Job’s claims to certainty are a pretence.
Calvin comments that when God is pleased to give a man long life, he may well have learnt many a thing; that men’s minds are better settled by age, and that young men cast forth many bubbles. ‘And yet for all that, we see that instead of profiting from long life, the majority go backwards .. Also there is no trusting in our own agedness in respect of God’s wisdom. For he deals with us as he pleases, both to young and old, as he says in the prophet Joel, “Behold the days shall come when I pour out my Spirit upon all flesh. You old men shall dream dreams … and your sons and daughters shall see visions.” In that place we see that God calls the young as well as the old, and women as well as men’ (Calvin – English updated). He faults the Papists who ground their faith on antiquity, as if this alone was a sufficient authority. The matter, he says, does not concern a score of years or four hundred or even a thousand, for we must have the everlasting truth which has been disclosed to us from the creation of the world. If we have that, our faith will be well settled.
