Behold, in this thou art not just. It would certainly not have been a just charge to make against God, that he counted Job as an enemy; and, so far as Job's statements go, it must be admitted that he had laid himself open to Elihu's rebuke.
But it is no logical "answer" to Job's charge to say, in reply to it, I will answer thee, that God is greater than man. Might does not constitute right, and it is a poor way of justifying God to urge that he is all-powerful, and may do what he likes.
So Cambyses was justified in his worst acts by the royal judges (Herod; 3:31); and so in an absolute monarchy it is always possible to justify the extremest acts of tyranny. Certainly God cannot act unjustly; but this is not because his doing a thing makes it right, but because his justice, is a law to his will, and he never wills to do anything that he has not previously seen to be just (see Cudworth's 'Immutable Morality,' which deserves the careful study, not alone of moralists, but also of theologians).
