Who is the maker of God? He pours ridicule on the madness of men who dare to frame gods; for it is a shocking and detestable thing that men should take so much upon them as to create God. Every person certainly will greatly abhor such madness; and yet men are blindly impelled by foolish passion to manufacture gods, and no warning restrains them. On the other hand, they will say that this never entered into any man's mind, and that injustice is done to them when they are accused of so great madness; just as the Papists in the present day say that we slander them, when we employ these arguments of the Prophet against them. But in vain do they rely on their sophistical reasonings for avoiding this charge. What the Prophet says is most true, that they are so mad as to think that they "make God;" for as soon as the stone or wood has been carved or polished, they ascribe to it divinity, run to it, make prayers, call upon it, and prostrate themselves before it, and in short, ascribe to it those things which they know to belong to God alone. Which is profitable for nothing. We ought carefully to observe this clause, which condemns as vain and useless all the images by which God is represented. Hence it follows not only that God is insulted, whenever his glory is changed into dead images, but that all who procure idols for themselves lose their pains and suffer damage. Papists allege that they are the books of the unlearned; but this is a paltry evasion, for the Prophet testifies that they are of no use whatever. Let them, therefore, either erase this proof from the Book of Isaiah, or acknowledge that images are vain and useless. Formerly he expressed something more, when he affirmed that nothing can be learned from them but falsehood. But on this subject we have said enough in the exposition of these passages. (Isaiah 40 and 41.)

Who hath formed a god - The Septuagint reads this verse in connection with the close of the previous verse, 'But they shall be ashamed who make a god, and all who sculpture unprofitable things.' This interpretation also, Lowth, by a change in the Hebrew text on the authority of a manuscript in the Bodleian library, has adopted. This change is made by reading כי kı̂y instead of מי mı̂y in the beginning of the verse. But the authority of the change, being that of a single MS. and the Septuagint, is not sufficient. Nor is it necessary. The question is designed to be ironical and sarcastic: 'Who is there,' says the prophet, 'that has done this? Who are they that are engaged in this stupid work? Do they give marks of a sound mind? What is, and must be the character of a man that bas formed a god, and that has made an unprofitable graven image?

Who hath formed a (o) god, or cast a graven image [that] is (p) profitable for nothing?
(o) Meaning that whatever is made by the hand of man, if it is valued as a god, is most detestable.
(p) By which appears their blasphemy, who call images the books of the laity, seeing that they are not only here called unprofitable, but in (Isaiah 41:24) abominable. Jeremiah calls them the work of errors, (Jeremiah 10:15), Habakkuk, a lying teacher (Habakkuk 2:18).

Who hath formed a god,.... Who ever made one? was such a thing ever known? or can that be a god which is made or formed? who so mad, foolish and sottish, as to imagine he has made a god? or is it possible for a creature to be the maker of a god? or any so stupid as to fancy he had made one? yet such there were, so void of understanding and reason, and even common sense: "or molten a graven image": first melted it, and cast it into a mould, and then graved and polished it, and called it a god?
that is profitable for nothing? or seeing it "is profitable for nothing", as a god; cannot see the persons, nor hear the prayers, nor relieve the distresses of those that worship it; and therefore it must be great folly indeed to make an image for such a purpose, which answers no end.

Who . . . ?--Sarcastic question: "How debased the man must be who forms a god!" It is a contradiction in terms. A made god, worshipped by its maker (1-Corinthians 8:4)!
