What does it mean that blessing and cursing should not come from the same mouth (James 3:10)?

The grand principle is plain beyond all question, that no inconsistency can be more gross than to employ the tongue, now in blessing the Supreme, now in cursing men that are made according to God's likeness. We are objects of His loving counsels, begotten of Him by the word of truth, and should be the last to curse any, as being blessed ourselves of mere mercy. It is not that fallen men have any intrinsic moral worth, as we above all should know from our own humbling experience. So we at least should never forget how they were brought into being as in God's likeness. How unbecoming in man, how shameless in us who bless the Lord and the Father, to curse men so made! Time was, beyond doubt, when we lived in malice and envy, hateful, hating one another; but the kindness and love of God our Saviour broke down our pride and purified our souls in obeying the truth through the Spirit unto unfeigned love of the brethren, and gave us a heart touched with divine grace toward all mankind. Instead then of cursing others, we want them to obey the truth, share the blessing, and join us in blessing Him Who is the source and giver of it all.

The incongruity is heightened by the figure of the next verse (10), "Out of the same mouth cometh forth blessing and cursing;" and by the quiet but pungent appeal, "Not so, my brethren, ought these things to be." The consistency of the Christian in its perfection is ever and only in Christ; and He is the sole and constant standard for us. What love in Him even for the vilest and bitterest of His foes! Called to inherit a blessing, may we not render evil for evil, or railing for railing, but contrariwise blessing, knowing that we are thereunto called. This is surely, dear brethren, what it ought to be.

Now we have, following, fresh illustrations to impress on the readers the incongruity and the enormity of injurious speech, all the worse for utterances of piety and propriety interchanged with it, and beyond just question condemnatory of it, as indicating the lack of the fear of God and of regard for man. The inspired writer's sense of its evil kindles into glowingly indignant questions, to which expostulation he himself supplies the answer in a few pregnant words.

Another feature that marks the tongue is brought before us in verses 7 and 8, and that is its unruly character. Man can tame all kinds of creatures but he cannot tame his own tongue. The reason for this is fairly evident. Speech is the great avenue by which the heart of man expresses itself, and hence the only way to really tame the tongue is to tame the heart. But this is a thing impossible to man. The grace and power of God are needed for it. In itself the tongue only gives expression to the deadly poison which lurks in the human heart.

In verse 9 and onwards a still further feature is mentioned. There is a strange inconsistency about the tongue when it is a question of the people of God. Unconverted people do not bless God, even the Father. They do not really know God at all, and much less do they know Him as Father. Christians know Him and bless Him in this way, and yet there are times when utterances of a very contrary sort come out of their lips. Sometimes they even go so far as cursing men who are made in the likeness of God; so that out of the same mouth goes forth both blessing and cursing. No wonder that James so emphatically says, "My brethren, these things ought not so to be."

(Vv. 7, 8). The tongue is untameable by nature. Every kind of creature has been tamed by mankind, but no man can tame the tongue. It is an unruly evil, full of deadly poison. Not only does it defile the body, but it can poison the mind. It has been truly said, “Many according to the flesh would avoid giving a blow, who cannot restrain a passionate or hard word against a neighbour.” How easy it is by a thoughtless or an unkind word to poison the mind of brethren against a brother.

(Vv. 9-12). Moreover, the tongue can be thoroughly inconsistent, for, while capable of blessing God, it can also curse man made in the likeness of God. Out of the same mouth blessing and cursing can proceed. This is contrary to nature, for no fountain can send forth sweet and bitter water, nor does a fig tree bear olives, nor a vine figs. By the ordinance of God the nature of a thing induces products according to its nature. Christians, as born of God and morally partakers of the divine nature, are in speech and acts to be consistent with God's ways.

The Apostle is not speaking of the tongue when used by grace and restrained by the Spirit, but of the tongue used under the influence of the flesh and energised by the devil. Nothing but the power of the Spirit filling the heart with the grace of Christ can restrain the tongue. When the heart is enjoying the grace and love of Christ, the tongue will speak in grace out of the abundance of the heart.

Blessing and curse may be expressed by the tongue. While on the one hand, the tongue is an instrument of evil and for evil, the tongue of the believer, on the other hand, should be an instrument of righteousness and for the glory of God. What greater occupation on earth is possible than true worship in Spirit and truth! Through the tongue we can praise and exalt the Lord, bear testimony to that worthy Name, tell others of Him and become channels for eternal blessing. But how quickly, if uncontrolled, it may be used in the service of sin. Peter uttered with his tongue his great, God-given confession, "Thou art the Christ, the Son of the living God." But a short time after, that same tongue became the mouthpiece of Satan, when he rebuked the Lord for saying that He would go to Jerusalem to suffer and to die. What an inconsistency the tongue of man reveals! No such thing is found in nature anywhere. A tree does not produce two kinds of fruit; a fig tree bears no Olives; a vine does not produce figs; nor does the same fountain gush forth salt water and sweet water.

The tongue therefore is regarded in scripture as a mighty instrument which a man may wield for good or ill among his fellows. Speech is the great means for the publication of the thought which arises in the heart and of the dissemination of its purifying or defiling influences among others. The mouth is the medium whereby man may worship God or blaspheme His holy name. So James says, "Therewith bless we God, even the Father, and therewith curse we men who are made after the similitude of God. Out of the same mouth proceeds blessing and cursing. My brethren, these things ought not so to be" (James 3:9-10). Hence, he that rules his spirit is mightier than he who takes a city, and "whoso keeps his mouth and his tongue keeps his soul from troubles" (Prow. 16:32; Prov. 21:23). But who can bring a clean thing out of an unclean? The seriousness of this problem James teaches when he says, "The tongue can no man tame; it is an unruly member," and, further, "So is the tongue among our members that it defiles the whole body" (James 3:6, 8). In the sense of this guilty contagiousness, Isaiah confessed that he was a man of unclean lips, and accordingly it was upon his mouth that the coal of cleansing was laid (Isa. 6:7).

So when man's blood was to be shed it was not his moral goodness but the place he held and dignity, his representing God as he had been set, but which made it unfit he should be killed. James will not have man cursed, and here "likeness" is the fit word; we bless what God is and curse His likeness - man, who was made in it, for so he speaks. Hence (as I have said elsewhere) He formed man spotless, sinless, free, with a will to be for ever used in the sphere he was placed in, and the centre of all the affections and reverence of the sphere he was placed in, and he stood alone as the centre of it all, the image of God. Christ will be, though far more, yet this, perfectly; being One that in the highest sense fully partakes of the divine nature.

From this point our Epistle takes up the ground of manifest and gross inconsistency. None but the most heedless can regard lightly a fault so self-condemnatory; nor can God either originate or sanction so plain a disorder and misuse of that excellent possession, the speech, conferred on man by His Creator. Least excusable is the inconsistency in such as own their relationship with God and the Lord.

"Therewith we bless the Lord and [the] Father, and therewith we curse men that are made according to God's likeness. Out of the same mouth cometh blessing and cursing. Not so, my brethren, ought these things to be" (vers. 9, 10).

A believer, by the power of the Spirit of God, may "bridle" his tongue, that is, put it under restraint; and this is surely a serious responsibility; but let no-one persuade himself that he has tamed his tongue; or he will almost certainly have painful occasion to find in experience that it is still "an unruly evil, full of deadly poison." Therefore it needs constant guarding and restraining.

How little we stop to think that with the same tongue we may heartily bless God, yet speak badly of men, whom God has created in his own likeness. The inconsistency of this should be a shame to us; yet who is not at some time guilty of it? Let us take to heart the exhortation that these things ought not to be, and seek grace to unsparingly judge any "speaking unadvisedly with our lips." For this very thing Moses was deprived of entering, into the land. (Num.20:12; Ps.106:32,33)

It is not my intention on this occasion to run through all the Scripture passages which speak of the mouth. I propose to confine myself to the four passages in the epistle to the Romans in which it is mentioned. These all regard it from the moral side — as the outlet for the heart. In Rom. 3 we have the divine indictment of man, presented in a string of quotations from the Prophets and the Psalms. Amongst them we find these terrible words from Psalm 10: "Whose mouth is full of cursing and bitterness." If the heart did not contain these evils the mouth could never give them forth. Here then we have an insight into the human heart. Let it be noted also that this awful quotation occurs in the apostle's description of religious Jews, not in his account of heathen Gentiles. We are reminded of James' exposure of the inconsistency of the tongue: "Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God." It is possible therefore to sing the praises of God on Sunday and be guilty of cursing and bitterness towards men on Monday. Oh, the appalling corruption of the human heart! Well might the Saviour say: "How can ye, being evil, speak good things? For out of the abundance of the heart the mouth speaks" (Matt. 12:34). Yet it is one of the hardest of all lessons to learn that the heart of every man is incurably wicked.

But the apostle goes on more fully into this question of the tongue. "If any offend not in word, he is a perfect man, able to bridle also the whole body." And yet how easily we let our tongues run on! In fact, the place that the apostle gives the tongue is that which governs the whole body. The bit in the horse's mouth is a small thing in itself, and yet the whole body is turned by it. The ships, in the midst of violent winds that act upon them, yet are turned about by a very small rudder, according to the direction that the helmsman gives. So, we may think little of the tongue, although it is the very thing by which we boast so much, but, verily, "How much wood can be kindled by how small a fire!" And here he breaks out into a description of it which is startling in its vehemence. "The tongue is a fire. The world of iniquity among our members is the tongue, which defileth the whole body, and setteth on fire the course of nature, and is set on fire of hell." Of course, he is speaking of it as unrestrained by the fear of God, or unguided by the power of the Spirit. How much might we speak of the wonderful power of the tongue on the other side! What a ministry of comfort and blessing is in it! But the best gifts are in their perversion just as fruitful for evil as they are good when used aright. The sweetest ties, the most precious relationships that God has instituted amongst men, are just in the same proportion fruitful for evil in their perversion. Nevertheless there is, no doubt, a special need for such a warning as this with regard to the tongue. How apt we are to be careless about it! How apt we are to release it somewhat from the control that we ought to exercise over it! How soon, if it escapes from such control, it does the damage which we know a little fire may! How much further evil may a little evil in it — mere unguarded words, as we say — excite in others! It is an untamable evil, says the apostle; that is, of course, naturally. We have always to govern it, saints as we may be. The liberty which is truly ours does not extend, as we know, to a liberty with regard to that body which is still unredeemed, which is dead because of sin; and among Christians, where is there, in fact, any source of evil, and so readily allowed to manifest itself, as the tongue? "It is a restless evil," says the apostle, always seeking expression, yet "full of death-bringing poison." "We bless the Lord on the one hand, and curse men on the other; men whom God has made in His own likeness. Blessing and cursing come out of the same mouth. How thorough an inconsistency, as the apostle urges! In nature you do not find such things. The fountain does not send forth sweet and bitter water out of the same opening; nor a fig tree yield olives; nor a vine, figs; nor can that which is salt produce sweet water. Nature itself in this way rebukes one who was meant to be the lord of nature, as the image of Him who is the Governor over all. He has, alas, yielded himself to the government of another, and thus he has lost the power of government, largely, over nature, but above all over himself. The child of God away from God displays in full reality the power of the fall, and, as the apostle urges here, the tongue is an eminent example of this.
