In the first place, the time calls for a comparison; since all the rest of mankind has been rejected for their ingratitude, he places the just man in the place of them all, asserting that he had found favour with God, not because he alone was deserving of favour, when the whole universal body of the human race had had benefits and mercies heaped on them, but because he alone had seemed to be mindful of the kindnesses which he had received.
In the second place, when the whole generation had been given over to destruction, with the exception of one single family, it followed inevitably that that remaining household should be asserted to have shown itself worthy of the divine grace, that it might be, as it were, a seed and a spark of a new race of mankind. And what could be a greater grace and mercy than that the man, of whom this is said, should be at the same time the end and beginning of the family of mankind?
