John 12:40

And thus the Evangelist tacitly explains it, when he adds, But though He had done so many miracles before them, yet they believed not on Him.

He means the miracles related above. It was no small wickedness to disbelieve against such miracles as those.

But why then did Christ come? Did He not know that they would not believe in Him? Yes: the Prophets had prohibited this very unbelief, and He came that it might be made manifest, to their confusion and condemnation; That the saying of Esaias the prophet might be fulfilled, which He spoke, Lord, who has believed, our report? and to whom has the arm of the Lord been revealed?

Who, i.e. So very few believed.

It is evident here that the arm of the Lord is the Son of God Himself. Not that the Father has a human fleshly form; He is called the arm of the Lord, because all things v ere made by Him. If a man had power of such a kind, as that without any motion of his body, what he said was forthwith done, the word of that man would be his arm. Here is no ground to justify, however, the error of those who say that the Godhead is one Person only, because the Son is the arm of the Father, and a man and his arm are not two persons, but one. These men do not understand, that the commonest things require to be explained often by applying language to them taken from other things in which there happens to be a likeness, [and that, when we are upon things incomprehensible, and which cannot be described as they actually are, this is much more necessary. Thus one man calls another man, whom he makes great use of, his arm; and talks of having lost his arm, of having his arm taken away from him.] But some mutter, and ask, What fault was it of the Jews, if it was necessary that the sayings of Esaias should be fulfilled? We answer, that God, foreseeing the future, predicted by the Prophet the unbelief of the Jews, but did not cause it. God does not compel men to sin, because He knows they will sin. He foreknows their sins, not His own. The Jews committed the Sin, which He who knows all things foretold they would commit.

That the saying of Esaias might be fulfilled: that here is expressive not of the cause, but of the event. They did not disbelieve because Esaias said they would; but because they would disbelieve, Esaias said they would.

But what follows involved a deeper question: Therefore they could not believe, because that Esaias said again, He has blinded their eyes, and hardened their hearts, that they should not see with their eyes, nor understand with their heart, and be converted, and 1 should heal them. That they should not believe; but if so, what sin is there in a man doing what he cannot help doing? And what is a graver point still, the cause is assigned to God; since He it is who blinded their eyes, and hardened their heart. This is not said to be the devil’s doing, but God’s. Yet if any ask why they could not believe, I answer, because they would not. For as it is to the praise of the Divine will that God cannot deny Himself, so is it the fault of the human will that they could not believe.

This is a common form of speech among ourselves. I cannot love such a man, meaning by this necessity only a vehement will. The Evangelist says could not, to show that it was impossible that the Prophet should lie, not that it was impossible that they should believe.

But the Prophet, you say, mentions another cause, not their will; viz. that God had blinded their eyes, and hardened their heart. But I answer, that they well deserved this. For God hardens and blinds a man, by forsaking and not supporting him; and this He may by a secret sentence, by an unjust one He cannot.

For He does not leave us, except we wish Him, as He said in Hosea, Seeing you have forgotten the law of your God, I will also forget your children. Whereby it is plain that we begin to forsake first, and are the cause of our own perdition. For as it is not the fault of the sun, that it hurts weak eyes, so neither is God to blame for punishing those who do not attend to His words.

And be converted, and I should heal them. Is not to be understood here, from the beginning of the sentence - that they should not see with their eyes, nor understand with their hearts, nor be converted; conversion being the free gift of God? or, shall we suppose that a heavenly remedy is meant; whereby those who wished to establish their own righteousness, were so far deserted and blinded, as to stumble on the stumbling stone, till, with confusion of face, they humbled themselves, es, and sought not their own righteousness which puffs up the proud, but God’s righteousness, which justifies the ungodly. For many of those who put Christ to death, were afterward troubled with a sense of their guilt; which led to their believing in Him. These things said Esaias, when he saw His glory, and spoke of Him. He saw Him not really, but figuratively, in prophetic vision. Be not deceived by those who say that the Father is invisible, the Son visible, making the Son a creature. For in the form of God, in which He is equal to the Father, the Son also is invisible; though He took upon Him the form of a servant, that He might be seen by men. Before His incarnation too, He made Himself visible at times to human eyes; but visible through the medium of created matter, not visible as He is.

His glory means the vision of Him sitting on His lofty throne: I saw the Lord sitting upon a throne. Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us?

Nevertheless, among the chief rulers also many believed on Him; but because of the Pharisees they did not confess Him, lest they should be put out of the synagogue. For they loved the praise of men more than the praise of God. The praise of God is publicly to confess Christ: the praise of men is to glory in earthly things.

As their faith grew, their love of human praise grew still more, and outstripped it.

These things he said to me in tones of the deepest anger, so that I was confounded and exceedingly afraid of him, for his figure was altered so that a man could not endure his anger. But seeing me altogether agitated and confused, he began to speak to me in more gentle tones; and he said: “O fool, senseless and doubting, do you not perceive how great is the glory of God, and how strong and marvellous, in that He created the world for the sake of man, and subjected all creation to him, and gave him power to rule over everything under heaven? If, then, man is lord of the creatures of God, and rules over all, is he not able to be lord also of these commandments? For,” says he, “the man who has the Lord in his heart can also be lord of all, and of every one of these commandments. …

Now, if there has been temerity in our retracing to primordial experiences the reasons for God’s having laid, and our duty (for the sake of God) to lay, restrictions upon food, let us consult common conscience. Nature herself will plainly tell with what qualities she is ever wont to find us endowed when she sets us, before taking food and drink, with our saliva still in a virgin state, to the transaction of matters, by the sense especially whereby things divine are handled; whether (it be not) with a mind much more vigorous, with a heart much more alive, than when that whole habitation of our interior man, stuffed with meats, inundated with wines, fermenting for the purpose of excremental secretion, is already being turned into a premeditatory of privies, (a premeditatory) where, plainly, nothing is so proximately supersequent as the savouring of lasciviousness. …

19. Moreover, so far as regards the Lord’s discourses, he does not cease to ascend to the sublimer and more extended utterances of which, from this point also, He delivered Himself. For he inserts a lofty address which the Lord spoke on the occasion when, through Philip and Andrew, the Gentiles expressed their desire to see Him, and which is introduced by none of the other evangelists. There, too, he reports the remarkable words which were spoken again on the subject of the light which enlightens and makes men the children of light. …

[5.] But vainglory is a thing powerful to blind even to very evident truths the minds of those ensnared by it, and to persuade them to dispute against what is allowed by others; nay, it instigates some who know and are persuaded of the truth to pretended ignorance and opposition. As took place in the case of the Jews, for they did not through ignorance deny the Son of God, but that they might obtain honor from the multitude; “they believed,” says the Evangelist, but were afraid, “lest they should be put out of the synagogue.” ( xii. 40 .) And so they gave up their salvation to others. For it cannot be that he who is so zealous a slave to the glory of this present world can obtain the glory which is from God. Wherefore He rebuked them, saying, “How can ye believe, which receive honor of men, and seek not the honor which cometh from God?” ( v. …

Ver. 39-41 . “They could not believe,” it saith, “because that Esaias said, Ye shall hear with your ears, and not understand. These things he said, when he saw His glory, and spake of Him.” Here again observe, that the “because,” and “spake,” refer not to the cause of their unbelief, but to the event. For it was not “because” Isaiah spake, that they believed not; but because they were not about to believe, that he spake. Why then doth not the Evangelist express it so, instead of making the unbelief proceed from the prophecy, not the prophecy from the unbelief? And farther on he putteth this very thing more positively, saying, “Therefore they could not believe, because that Esaias said.” He desires hence to establish by many proofs the unerring truth of Scripture, and that what Isaiah foretold fell not out otherwise, but as he said. …

Ver. 40 . “He hath blinded their eyes, and hardened their heart, lest they at any time should see with their eyes, and understand with their heart.”
