What do the words of Job mean? The Omnipotence of God? The impossibility for man to resist God? Probably, and that also. But in the context of the entire book, they probably all the same acquire another sense, not so obvious. What is the main problem of Job? What worries him most? The misfortunes that struck him? Probably, no. However, of course the starting point was exactly the misfortunes. But oppressed Job mostly makes the fact that he perceived these misfortunes as an injustice, and moreover as an injustice from God. He is troubled, he cannot understand: is God unjust? Or He simply doesn’t care about people? Both were for Job equally a spiritual disaster, quite as, certainly for any sincere religious person. And Job, naturally as a sincere person, began to ask very "uncomfortable" questions to God, and moreover in a very rude form (to the great displeasure of his friends, who used all the theological arguments available to them to reason with Job). And then, Job finally heard God.
The God, Who paradoxically had promised nothing to him and had answered him to none of the questions and nor any of the charges pronounced by Job to His face. What thus urged Job to reconsider his previous opinions? Is it only the overwhelming greatness of God, in front of which man cannot resist? Probably, not only it. If everything was so easy, God would not have needed to intervene, the arguments moved forward by the friends of Job would have been enough. Apparently, Job understood something else: he was persuaded that God has answers to his given questions, including the question about the sufferings of an innocent righteous. Besides, God is far from wanting to justify evil and suffering: they, it seems, are generally deprived of any sense and have no justification.
He, probably, simply let Job know that He has means to make these sufferings as former, and will come in the day, when He will do it. Such an answer would really mean that God can do anything, even what turns out, according to the laws of our non-transformed world, in principle impossible. He can do anything, not because He has the power to destroy the world and create it again, but because for Him there are no hopeless situations and irretrievable losses, for His righteous man He will find a way out of any impasse. Although, of course this way out can turn out not totally such or even totally not such as the person who shouts out to God for help and injustice imagines himself.
