Hebrews 4:12

He did not come "to bring peace on earth … but a sword," and Scripture calls the Word of God a "two-edged sword" because of the two Testaments.

The texts of the New Testament, which we have discussed, are things said by Himself about Himself. Isaiah, however, He said that His mouth had been set by His Father as a sharp sword, and that He was hidden under the shadow of His hand, made like to a chosen shaft and kept close in the Father's quiver, called His servant by the God of all things, and Israel, and Light of the Gentiles. The mouth of the Son of God is a sharp sword, for "The word of God is living, and active, and sharper than any two-edged sword, and piercing to the dividing of soul and spirit, of both joints and marrow, and quick to discern the thoughts and intents of the heart." And indeed He came not to bring peace on the earth, that is, to corporeal and sensible things, but a sword, and to cut through, if I may say so, the disastrous friendship of soul and body, so that the soul, committing herself to the spirit which was against the flesh, may enter into friendship with God. Hence, according to the prophetic word, He made His mouth as a sword, as a sharp sword. Can any one behold so many wounded by the divine love, like her in the Song of Songs, who complained that she was wounded: "I am wounded with love," and find the dart that wounded so many souls for the love of God, in any but Him who said, "He hath made Me as a chosen shaft."

Jesus endured the cross, disregarding the shame, and therefore is seated at the right hand of God. And those who imitate him by disregarding the shame shall sit with him and rule in the heavens with him, who came not to bring peace upon the earth but upon the souls of his followers and to bring a sword upon the earth. Since "the Word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and marrow, and discerning the thoughts and intentions of the heart," this word above all now bestows on our souls the prize of that peace which surpasses all understanding, which he left to his apostles. And it brings a sword between the earthly image and the heavenly in order that when he receives our heavenly image we may be made fully heavenly, if we are worthy not to be cut in two.

He used the phrase "laid bare to the eyes of him" as a metaphor from sacrificed beasts, which lie completely mute, the slaughter doing away with their life, and along with their life their cries. In similar manner, he is saying, when we also are …

"The word of God is … sharper than any two-edged sword." Now the holy depth of divine Scripture is expressed in such common language that everyone immediately takes it in. But buried within it are hidden senses of truth, so that the vital meaning must …

In the next place, lest hearing the words "after the same example," thou shouldest think that the punishment is the same, hear what he adds; "For the Word of God is quick and powerful, and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." In these words he shows that He, the Word of God, wrought the former things also, and lives, and has not been quenched. Do not then when hearing the Word, think of it lightly. For "He is sharper," he says, "than a sword." Observe His condescension; and hence consider why the prophets also needed to speak of saber and bow and sword. "If ye turn not," it is said, "He will whet His sword, He hath bent His bow and made it ready." (Ps. vii. 12.) For if now, after so long a time, and after their being perfected, He cannot smite down by the name of the Word alone, but needs these expressions in order to show the superiority arising from the comparison of the Gospel with the law: much more then of old. "Piercing," he says, "even to the dividing asunder of soul and spirit." What is this? He hinted at something more fearful. Either that He divides the spirit from the soul, or that He pierces even through them disembodied, not as a sword through bodies only. Here he shows, that the soul also is punished, and that it thoroughly searches out the most inward things, piercing wholly through the whole man. "And is a discerner of the thoughts and intents of the heart, neither is there any creature that is not manifest in His sight." In these words most of all he terrified them. For do not (he says) be confident if ye still stand fast in the Faith, but without full assurance. He judges the inner heart, for there He passes through, both punishing and searching out.

For lest on hearing the things that belong to the soul we should grow negligent, he adds also what concerns the body. For then it is as a king, when his officers are guilty of some great fault, first strips them (say) of their command, and after depriving them of their belt, and their rank, and their herald, then punishes them: so also in this case the sword of the Spirit works.

Then, lest any think that they will simply be deprived of rest only, he adds also the punishment, saying, "For the Word of God is quick, and powerful; and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow: and is a discerner of the thoughts and intents of the heart." Here he is speaking of Hell and of punishment. "It pierceth" (he says) into the secrets of our heart, and cutteth asunder the soul. Here it is not the failing of carcasses nor, as there, the being deprived of a country, but of a heavenly kingdom; and being delivered to an everlasting hell, and to undying punishment and vengeance.

He says, "division of soul and spirit." The soul has a special feeling for the body, but the grace of the Holy Spirit draws against the body to the heavenly things.

It was necessary that our Hierarch be endowed with awareness, in regard to the threefold wisdom within Him: the innate, that is, the wisdom of angels and of the first man, the infused, and the eternal. Through the first, He knows all things which we …

Do you not shudder when you hear God each day saying to you through the whole of the divine Scripture, "Let no evil speech come out of your mouth"? For truly I say to you for any idle word you will give an account, and …

Then (v. 12) he gives the reason for this advice, and especially in regard to the danger. But this reason is taken on the part of Christ in Whom there are two natures: one is the divine according to which he is the Word of …

Just as then, he says, it was not war, not the sword that destroyed them, but the word of God—for they fell of their own accord—so it will be with us as well. For the same word that punished them will also punish us: it …

It is powerful to batter down Satan's kingdom, and to set up the kingdom of Christ upon the ruins thereof. (3.) It is sharper than any two-edged sword; it cuts both ways; it is the sword of the Spirit, Eph. vi. It is the two-edged sword that cometh out of the mouth of Christ, Rev. i.

For the word of God is quick and powerful,....

For the word of God is quick, and powerful - Commentators are greatly divided concerning the meaning of the phrase Ὁ λογος τον Θεου, the word of God; some supposing the whole of Divine revelation to be intended; others, the doctrine of the Gospel faithfully preached; others, the mind of God or the Divine intellect; and others, the Lord Jesus Christ, who is thus denominated in Joh 1:1, etc., and Rev 19:13; the only places in which he is thus incontestably characterized in the New Testament. The disputed text, 1Jn 5:7, I leave at present out of the question.

Re 19:15 similarly represents the Word's judicial power as a sharp sword going out of Christ's mouth to smite the nations. The same word which is saving to the faithful (Heb 4:2) is destroying to the disobedient (2Co 2:15, 16). The personal Word, to whom some refer the passage, is not here meant: for He is not the sword, but has the sword.

THOSE who are fond of a labyrinth of exposition will find a maze perplexing to the last degree if they will read the various commentators and expositors upon this verse. This is the question—By the Word of God, are we here to understand the Incarnate Word, the Divine Logos, who was in the beginning with God? Or does the passage relate to this inspired Book, and to the Gospel, which is the kernel of it, as it is set forth in the preaching of the Truth in the power of the Holy Spirit? You shall find Dr.

THOSE who are fond of a labyrinth of exposition will find a maze perplexing to the last degree if they will read the various commentators and expositors upon this verse. This is the question—By the Word of God, are we here to understand the Incarnate Word, the Divine Logos, who was in the beginning with God? Or does the passage relate to this inspired Book, and to the Gospel, which is the kernel of it, as it is set forth in the preaching of the Truth in the power of the Holy Spirit? You shall find Dr. John Owen, with a very large number of eminent servants of God, defending the first theory, that the Son of God is doubtless here spoken of. And I confess that they seem to me to defend it with arguments which I should not like to controvert. Much more is to be said on this side of the question than I can here bring before you. On the other side, we find John Calvin, with an equally grand array of divines, all declaring that it must be the Book that is meant, the Gospel, the Revelation of God in the Book. Their interpretation of the passage is not to be set aside and I feel convinced that they all give as good reasons for their interpretation as those who come to the other conclusion. Where such Doctors differ, I am not inclined to present any interpretation of my own which can be set in competition with theirs though I may venture to propound one which comprehends them all and so comes into conflict with none. It is a happy circumstance if we can see a way to agree with all those who did not themselves agree. But I have been greatly instructed by the mere fact that it should be difficult to know whether in this passage the Holy Spirit is speaking of the Christ of God, or the Book of God. This shows us a great Truth of God which we might not otherwise have so clearly noted.

For the word of God - The design of this and the following verse is obvious. It is to show that we cannot escape the notice of God; that all insincerity, unbelief, hypocrisy, will be detected by him; and that since our hearts are perfectly open before him, we should be sincere and should not attempt to deceive him. The sense is, that the truth of God is all-penetrating and searching, and that the real thoughts and intents of the heart will be brought to light, and that if there is insincerity and self-deception there can be no hope of escape. There has been a great variety of opinion here about the meaning of the phrase “the Word of God.” Some have supposed that it means the Lord Jesus; others, the whole of the divine revelation; others the gospel; others the particular threatening referred to here. The “Word of God” is “what God speaks” - whether it be a promise or a threatening; whether it be Law or gospel; whether it be a simple declaration or a statement of a doctrine. The idea here is, that what “God had said” is suited to detect hypocrisy and to lay open the true nature of the feelings of the soul, so that there can be no escape for the guilty. His “truth” is adapted to bring out the real feelings, and to show man exactly what he is. Truth always has this power - whether preached, or read, or communicated by conversation, or impressed upon the memory and conscience by the Holy Spirit. There can be no escape from the penetrating, searching application of the Word of God. That truth has power to show what man is, and is like a penetrating sword that lays open the whole man; compare Isa 49:2. The phrase “the Word of God” here may be applied, therefore, to the “truth” of God, however made known to the mind. In some way it will bring out the real feelings, and show what man is. Is quick - Greek ζῶν zōn - “living.” It is not dead, inert, and powerless. […]
