Job 35:7

These words mean, you will do no wrong to him, and you will not be more useful to him by being righteous. In fact, he said, "If I have sinned, what shall I be able to do?" What shall I do to you? Elihu says, Why did you say that? Does God care about the fact that you sinned, as if he is the victim of an injustice or as if he is suffering damage?

He begins from what he had said last, showing that God cannot be helped or harmed by our good and evil works, and this is so because of his high character. So he says, "If you sin," against yourself or God, "what harm will you …

Look unto the heaven, and see, and behold the sky, that it is higher than thou. If thou hast sinned, what wilt thou hurt Him? If thine iniquities have been multiplied, what wilt thou do against Him? If, moreover, thou hast acted justly, what wilt thou give Him, or what will He receive of thy hand? Although these words ought not to have been said to blessed Job, who knew greater truths, yet the things, which are said, are true, namely, that neither do our sins hurt God, nor our good deeds assist Him. Whence he followed, and added, (ver. 8.) Thine iniquity will hurt a man that is like thee, and thy righteousness will profit the son of man. But amongst these things we must carefully notice that which he says, Look into the heavens, and see, and behold the sky, that it is higher than thou. For from speaking in this way he doubtless signifies, that Job should consider, how much less he could either benefit, or injure, God by his conduct, since he could neither benefit, nor injure, the loftiness of the heaven, or of the sky. For although we can understand by the heaven, or the sky, the heavenly powers, who are ever steadily gazing on the sight of the Godhead, (in order that, when we behold that the angelic spirits are still far distant from us, we may acknowledge how far we are distant below, from the Creator and Lord of spirits Himself,) yet nothing prevents our understanding by them in this place the material substance of heaven and sky. For if we look attentively at outward things, we are recalled by their very means to inward things. For the wonderful works of the visible creation, are the footsteps of our Creator. For we cannot as yet behold Him Himself; but we are yet tending to a sight of Him, if we admire Him in these things which He has made. […]

If thou be righteous, what givest thou him?.... All righteousness is of God that any creatures have.

Our religion brings no accession at all to his felicity. He is so far from being beholden to us that we are beholden to him for making us righteous and accepting our righteousness; and therefore we can demand nothing from him, nor have any reason to complain if we have not what we expect, but to be thankful that we have better than we deserve.
