Isaiah

THREE PICTURES OF ONE REALITY

Isa_31:5 .

The immediate occasion of this very remarkable promise is, of course, the peril in which Jerusalem was placed by Sennacherib’s invasion; and the fulfilment of the promise was the destruction of his army before its gates. But the promise here, like all God’s promises, is eternal in substance, and applies to a community only because it applies to each member of that community. Jerusalem was saved, and that meant that every house in Jerusalem was saved, and every man in it the separate object of the divine protection So that all the histories of Scripture, and all the histories of men in the world, are but transitory illustrations of perennial principles, and every atom of the consolation and triumph of this verse comes to each of us, as truly as it did to the men that with tremulous heart began to take cheer, as they listened to Isaiah. There is a wonderful saying in one of the other prophets which carries that lesson, where, bringing down the story of Jacob’s struggle with the angel of Peniel to the encouragement of the existing generation, he says,’ He spake to us .’ They were hundreds of years after the patriarch, and yet had fallen heirs to all that God had ever said to him So, from that point of view, I am not spiritualising, or forcing the meaning of these words, when I bring them direct into the lives of each one of ourselves.

I. And, first, I would note the very striking and beautiful pictures that are given in these verses.

There are three of them, on each of which I must touch briefly. ‘As birds flying, so will the Lord of hosts defend Jerusalem.’ The form of the words in the original shows that it is the mother-bird that is thought about. And the picture rises at once of her fluttering over the nest, where the callow chickens are, unable to fly and to help themselves. It is a kind of echo of the grand metaphor in the song that is attributed to Moses, which speaks of the eagle fluttering over her nest, and taking care of her young. Jerusalem was as a nest on which, for long centuries, that infinite divine love had brooded. It was but a poor brood that had been hatched out, but yet ‘as birds flying’ He had watched over the city. Can you not almost see the mother-bird, made bold by maternal love, swooping down upon the intruder that sought to rob the nest, and spreading her broad pinion over the callow fledglings that lie below? That is what God does with us. As I said, it is a poor brood that is hatched out. That does not matter; still the Love bends down and helps. Nobody but a prophet could have ventured on such a metaphor as that, and nobody but Jesus Christ would have ventured to mend it and say, ‘As a hen gathereth her chickens under her wings,’ when there are hawks in the sky. So He, in all the past ages, was the One that ‘as birds flying . . . defended’ His people, and would have gathered them under His wings, only they would not.

Now, beautiful as this metaphor is, as it stands, it seems to me, like some brilliant piece of colouring, to derive additional beauty from its connection with the background upon which it stands out. For just a verse before the prophet has given another emblem of what God is and does, and if you will carry with you all those thoughts of tenderness and maternal care and solicitude, and then connect them with that verse, I think the thought of His tenderness will start up into new beauty. For here is what precedes the text: ‘Like as a lion, and the young lion roaring on his prey when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor bow himself for the noise of them. So shall the Lord of hosts come down to fight for Mount Zion.’ Look at these two pictures side by side, on the one hand the lion, with his paw on his prey, and the angry growl that answers when the shepherds vainly try to drag it away from him. That is God. Ay! but that is only an aspect of God. ‘As birds flying, so the Lord will defend Jerusalem.’ We have to take that into account too. This generation is very fond of talking about God’s love; does it believe in God’s wrath? It is very fond of speaking about the gentleness of Jesus; has it pondered that tremendous phrase, ‘the wrath of the Lamb’? The lion that growls, and the mother-bird that hovers-God is like them both. That is the first picture that is here.

The second one is not so obvious to English readers, but it is equally striking, though I do not mean to dwell upon it. The word that is translated in our text twice, ‘defend’ and ‘defending’-’So will the Lord of hosts defend Jerusalem, and defending will deliver’-means, literally, ‘shielding.’ Thus we have the same general idea as that in the previous metaphor of the mother-bird hovering above the nest: God is like a shield held over us, and so flinging off front the broad and burnished surface of the Almighty buckler, all the darts that any foe can launch against as. ‘Our God is a Sun and Shield.’ I need not enlarge on this familiar metaphor.

But the third picture I wish to point to in more detail: ‘Passing over, He will deliver.’ Now, the word that is there rendered ‘passing over,’ is almost a technical word in the Old Testament, because it is that employed in reference to the Passover. And so you see the swiftness of genius with which the prophet changes his whole scene. We had the nest and the mother-bird, we had the battlefield and the shield; now we are swept away back to that night when the Destroying Angel stalked through the land, and ‘passed over’ the doors on which the blood had been sprinkled. And thus this God, who in one aspect may be likened to the mother-bird hovering with her little breast full of tenderness, and made brave by maternal love conquering natural timidity, and in another aspect may be likened to the broad shield behind which a man stands safe, may also be likened to that Destroying Angel that went through Egypt, and smote wherever there were not the tokens of the blood on the lintels, and ‘passed over’ wherever there were. Of course, the original fulfilment of this third picture is the historical case of the army of Sennacherib; outside the walls, widespread desolation; inside the walls, an untroubled night of peace. That night in Egypt is paralleled, in the old Jewish hymn that is still sung at the Passover, with the other night when Sennacherib’s men were slain; and the parallel is based on our text. So, then, here is another illustration of what I started with saying, that the past events of Scripture are transient expressions of perennial principles and tendencies. For the Passover night was not to be to the contemporaries of the prophet an event receding ever further into the dim distance, but it was a present event, and to be reproduced in that catastrophe when ‘in the morning when they arose, they were all dead corpses.’ And the event is being repeated to-day, and will be for each of us, if we will.

So, then, there are these three pictures-the Nest and the Mother-bird, the Battlefield and the Shield, Egypt and the Destroying Angel.

II. We note the reality meant by these pictures.

They mean the absolute promise from God of protection for His people from every evil. We are not to cut it down, not to say that it applies absolutely in regard to the spiritual world, but that it does not apply in regard to temporal things. Yes, it does entirely, only you have to rise to the height of God’s conception of what is good and what is evil in regard to outward things, before you understand how completely, and without qualification or deduction, this promise is fulfilled to every man that puts his trust in Him. Of course, I do not need to remind you, for your own lives will do so sufficiently, that this hovering protector, this strong Shield, this Destroying Angel that passes by our houses if the blood is on the threshold, does not guarantee us any exemption from the common ‘ills that flesh is heir to.’ We all know that well enough. But what does it guarantee? That all the poison shall be wiped off the arrow, that all the evil shall be taken out of the evil, that it will change its character, that if we observe the conditions, the sharpest sorrow will come to us with this written on it by the Father’s hand, ‘With My love to My child’; that pain will be discipline, and discipline will be blessed. Ah! dear friends! I am sure there are many of us that can set to our seals that God is true in this matter, and that we have found that His rod does blossom, and that our sorest sorrows have been our greatest mercies, drawing us nearer to Him; ‘Defending He will deliver, and passing over He will preserve.’

III. And now let me remind you of the way by which we can make the reality of these pictures ours.

You know that all the promises and prophecies of the Old Testament are conditional, and that there are many of them that were never fulfilled, and were spoken in order that they might not be fulfilled, if only the people took warning. I wish folk would carry a little more consciously in their minds that principle in interpreting them all, and in asking about their fulfilment. Not only in regard to these ancient events, but in regard to our individual experience, God’s promises and threatenings are conditional.

Take that first metaphor of the hovering mother-bird. Listen to this expansion of it in one of the psalms: ‘He shall cover thee with His feathers, and under His wings shalt thou trust.’ The word for trust here means to ‘fly into a refuge.’ Can you not see the picture? A little brood round the parent bird, frightened by some beast of prey, or hovering hawk in the sky, and fluttering under its wings, and all safe and huddled together there close against the warm breast, and in amongst the downy feathers. ‘Under His wings shalt thou trust.’ Put thou thy trust in God, and God is to thee the hovering bird, the broad shield, the Angel that ‘passes over.’

Take the other picture of the Passover night. Only by our individual faith in Jesus Christ as our individual Saviour can we put the blood on our door-posts so that the Destroying Angel shall pass by. So, if we would have the sweetness of such words as these fulfilled in our daily lives, however disturbed and troubled and sorrowful and solitary they may be, the first condition is that under His wings shall we flee for refuge, and we do so by trust in Him.

But having thus fled thither, we must continue there, if we would continue under His protection. Such continuance of safety because of continuous faith is possible only by continued communion. Remember our Lord’s expansion of the metaphor in His lament: ‘How often would I have gathered thy children together as a hen gathereth her chickens under her wings, and ye would not.’ We can resist the drawing. We can get away from the shelter of the wing. We can lift up our wills against Him. And what becomes of the chicken that does not run to the mother’s pinions when the hawk is hovering? That is what becomes of the man that stops outside the refuge in Christ, or that by failure of his faith departs from that refuge. ‘Ye would not; therefore your house is left unto you desolate.’ That house, in the Jerusalem which God ‘defends,’ is not defended.

Another condition of divine protection is obedience. We need not expect that God will take care of us, and preserve us, when we did not ask His leave to get into the dangerous place that we find ourselves in. Many of us do the converse of what the Apostle condemns, we begin ‘in the flesh,’ and think we shall end ‘in the Spirit’; which being translated is, we do not ask God’s leave to do certain things, to enter into certain engagements or arrangements with other people, and the like, and then we expect God to come and help us in or out of them. That is by no means an uncommon form of delusion. You remember what Jesus Christ said when the Devil tried to entice Him to do a thing of that sort, by quoting Scripture to Him-’He shall give His angels charge concerning Thee, to keep Thee in all Thy ways. Cast Thyself down. Trust to the promise as a kind of parachute to keep Thee from falling bruised on the stones of the Temple-court.’ Christ’s answer was: ‘Thou shalt not tempt the Lord thy God.’ You will not get God’s protection in ways of your own choosing.

And so, brethren, ‘all things work together for good to them that love,’ to them that trust, to them that keep close, to them that obey. And for such the old faithful promise will be faithful and new once more, ‘Because He hath set His love upon Me, therefore will I deliver Him’-that will be the summing up of our lives; ‘and I will set Him on high because He hath known My Name,’ that will be the meaning of our deaths.

Verse 9

Isaiah

THE LORD’S FURNACE

Isa_31:9 .

This very remarkable characterisation of God stands here as a kind of seal, set upon the preceding prophecy. It is the reason why that will certainly be fulfilled. And what precedes is mainly a promise of a deliverance for Israel, which was to be a destruction for Israel’s enemies. It is put in very graphic and remarkable metaphors: ‘Like as a lion roareth on his prey when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor abase himself for the noise of them: so shall the Lord of hosts come down to fight for Mount Zion.’ The enemies of Israel are picturesquely and poetically represented as a crowd of shepherds vainly trying to scare a lion by their shouts. He stands undaunted, with his strong paw on his prey, and the boldest of them durst not venture to drag it from beneath his claws. So, says Isaiah, with singularly daring imagery, God will put all His strength into keeping fast hold of Israel, and no one can pluck His people from His hands.

Then, with a sudden and striking change of metaphor, the prophet passes from a picture of the extreme of fierceness to one of the extreme of tenderness. ‘As birds flying’-mother birds fluttering over their nests-’so will the Lord of hosts defend Jerusalem,’ hovering over it and going from side to side to defend with His broad pinions, ‘passing over, He will preserve it.’ These figures are next translated into the plain promise of utter discomfiture and destruction, panic and flight as the portion of the enemies of Israel, and the whole has this broad seal set to it, that He who promises is ‘the Lord, whose fire is in Zion, and His furnace in Jerusalem.’

We shall not understand these great words if we regard them as only a revelation of destructive and terrible power. They are that indeed, but they are far more than that. It is the very beauty and completeness of this emblem that has a double aspect, and is no less rich in joy and blessing than pregnant with warning and terror. As Isaiah says in another place, Jerusalem is ‘Ariel,’ which probably means ‘the hearth of God.’ His presence in the city is as a fire for the comfort and defence of the happy inhabitants, and at the same time for the destruction of all evil and enemies. Far more truly than He dwelt in the city of David does God dwell in the Church, and His presence is its security. What, then, of instruction and hope may we gather from this wonderful emblem?

I. In the Church, God is present as a great reservoir of fervid love.

Every language has taken fire as the symbol of love and emotion. We speak so naturally of warm love, fervent feeling, glowing earnestness, ardent enthusiasm and the like, that we are scarcely aware of using figurative language. We do not usually ascribe emotion to God, but surely the deepest and most sacred of the senses in which it is true that fire is His emblem, is that He is love. His fire is in Zion. He dwells in His Church, a storehouse of blazing love, heated seventy times seven hotter than any creatural love, and pouring out its ardours for the quickening and gladdening of all who walk in the light of that fire, and thaw their coldness at its blaze.

Then, if so, how comes it that so many Christian Churches are ice-houses instead of furnaces? How comes it that they who profess to live in the Zion where this fire flames are themselves so cold? If God’s blazing furnace is in Jerusalem, it should send the thermometer up in all the houses of the city. But what a strange contradiction it is for men to be in God’s Church, the very focus and centre of His burning love, and themselves to be almost down below zero in their temperature! The Christian Church ought to be all aflame in all its members, with the fire of love kindled and alight from God Himself. Every community of Christian people ought to radiate warmth and light which it has absorbed from its present God. Our love ought to answer His, and, being caught and kindled from that mighty fire, should throw back to its source some of the heat received, in fervours of reflected love, and should pour the rest beneficently on all around. Love to God and love to man are regarded in Christian morals as beams of the same fire, only travelling in different directions. But what a miserable contrast to such an ideal the reality in so many of our churches is! A fiery furnace with its doors hung with icicles is no greater a contradiction and anomaly than a Christian Church or a single soul, which professes to have been touched by the infinite loving kindness of God, and yet lives as cold and unmoved as we do. The ‘Lord’s fire is in Zion.’ Are there any tokens of that fire amongst us, in our own hearts and in our collective temperature as Christian Churches?

There is no religion worth calling so which has not warmth in it. We hear a great deal from people against whom I do not wish to say a word, about the danger of an ‘emotional Christianity.’ Agreed, if by that they mean a Christianity which has no foundation for its emotion in principle and intelligence; but not agreed if they mean to recommend a Christianity which professes to accept truths that might kindle a soul beneath the ribs of death and make the dumb sing, and yet is never moved one hair’s-breadth from its quiet phlegmaticism. There is no religion without emotion. Of course it must be intelligent emotion, built upon the acceptance of divine truth, and regulated and guided by that, and so consolidated into principle, and it must be emotion which works for its living, and impels to Christian conduct. These two provisoes being attended to, then we can safely say that warmth is the test of life, and the readings of the thermometer, which measure the fervour, measure also the reality of our religion. A cold Christian is a contradiction in terms. If the adjective is certainly applicable, I am afraid the applicability of the noun is extremely doubtful. If there is no fire, what is there? Cold is death.

We want no flimsy, transitory, noisy, ignorant, hysterical agitation. Smoke is not fire. If the temperature were higher, and the fire more wisely fed, there would not be any. But we do want a more obvious and powerful effect of their solemn, glorious, and heart-melting beliefs on the affections and emotions of professing Christians, and that they may be more mightily moved by love, to all heroisms and service and enthusiasms and to consecration which shall in some measure answer to the glowing heart of that fire of God which flames in Zion.

II. God’s revelation of Himself, and presence in His Church, are an instrument of cleansing.

Fire purifies. In our great cities now there are ‘disinfecting ovens,’ where infected articles are taken, and exposed to a high temperature which kills the germs of disease, so that tainted things come out sweet and clean. That is what God’s furnace in Zion is meant to do for us. The true way of purifying is by fire. To purify by water, as John the Baptist saw and said, is but a poor, cold way of getting outward cleanliness. Water cleanses the surface, and becomes dirty in the process. Fire cleanses within and throughout, and is not tainted thereby. You plunge some foul thing into the flame, and, as you look, the specks and spots melt out of it. Raise the temperature, and you kill the poison germs. That is the way that God cleanses His people; not by external application, but by getting up the heat. The fire of His love, the fire of His spirit, is, as St. Bernard says, a blessed fire, which ‘consumes indeed, but does not hurt; which sweetly burns and blessedly lays waste, and so puts forth the force and fire against our vices, as to display the operation of the anointing oil upon our souls.’ The Hebrew captives were flung into the fiery furnace. What did it burn? Only their bonds. They themselves lived and rejoiced in the intense heat. So, if we have any real possession of the divine flame, it will burn off our wrists the bands and chains of our old vices, and we shall stand pure and clean, emancipated by the fire which will consume only our sins, and be for our true selves as our native home, where we walk at liberty and expatiate in the genial warmth. That is the blessed and effectual way of purifying, which slays only the death that we carry about with us in our sin, and makes us the more truly living for its death. Cleansing is only possible if we are immersed in the Holy Ghost and in fire, as some piece of foul clay, plunged into the furnace, has all the stains melted out of it. For all sinful souls seeking after cleansing, and finding that the ‘damned spot’ will not ‘out’ for all their washing, it is surely good news and tidings of great joy that the Lord has His fire in Zion, and that its purifying power will burn out all their sin.

III. Further, there is suggested another thought: that God, in His great revelation of Himself, by which He dwells in His Church, is a power of transformation.

Fire turns all which it seizes into fire. ‘Behold how much wood is kindled by how small a fire’ R.V.. The heap of green wood with the sap in it needs but a tiny light pushed into the middle, and soon it is all ablaze, transformed into ruddy brightness, and leaping heavenwards. However heavy, wet, and obstinate may be the fuel, the fire can change it into aspiring and brilliant flame.

And so God, coming to us in His ‘Spirit of burning,’ turns us into His own likeness, and makes us possessors of some spark of Himself. Therefore it is a great promise, ‘He shall baptize you in the Holy Ghost, and in fire.’ He shall plunge you into the life-giving furnace, and so ‘make His ministers like a flame of fire,’ like the Lord whom they serve. The seraphim who stand round the throne are ‘burning’ spirits, and the purity which shines, the love which glows, the swift life which flames in them, are all derived from that unkindled and all-animating Fire who is their and our God. The transformation of all the dwellers in Zion into miniature likenesses of this fire is the very highest hope that springs from the solemn and blessed truth that the Lord has His fire in Zion, and His furnace in Jerusalem.

IV. But, further, this figure teaches that the same divine fire may become destructive.

The emblem of fire suggests a double operation, and the very felicity of it as an emblem is that it has these two sides, and with equal naturalness may stand for a power which quickens, and for one which destroys. The difference in the effects springs not from differences in the cause, but in the objects with which the fire plays. The same God is the fire of life, the fire of love, of purifying and transformation and glad energy to whosoever will put his trust in Him, and a fire of destruction and anger unto whosoever resists Him. The alternative stands before every soul of man, to be quickened by fire or consumed by it. We may make the furnace of God our blessedness and the reservoir of a far more joyful and noble life than ever we could have lived in our coldness; or we may make it terror and destruction. There lie the two possibilities before every one of us. We cannot stand apart from Him; we have relations with Him, whether we will or no; He is something to us. He is, and must be for all, a flaming fire. We can settle whether it shall be a fire which is life-giving unto life, or a fire which is death-giving unto death.

Here are two buildings: the one the life of the man that lives apart from God, and therefore has built only with wood, hay, and stubble; the other the life of the man that lives with God and for Him, and so has built with gold, silver, and precious stones. The day and the fire come; and the fates of these two are opposite effects of the same cause. The licking tongues surround the wretched hut, built of combustibles, and up go wood and hay and stubble, in a smoking flare, and disappear. The flames play round the gold and silver and precious stones, and every leap of their light is answered by some facet of the gems that flash in their brilliancy, and give back the radiance.

You can settle which of these two is to be your fate. ‘The Lord’s fire is in Zion, and His furnace in Jerusalem.’ To those who, by faith in that dear Lord who came to cast fire on earth,’ have opened their hearts, to the entrance of that searching, cleansing flame, and who therefore burn with kindred and answering fervours, it is joy to know that their ‘God is a consuming fire,’ for therein lies their hope of daily purifying and ultimate assimilation. To those, on the other hand, who have closed their hearts to the warmth of His redeeming love in Christ, and the quickening of His baptism by fire, what can the knowledge be but terror, what can contact with God in judgment be but destruction? ‘The day cometh, it burneth as a furnace; and all the proud, and all that work wickedness, shall be as stubble, and the day that cometh shall burn them up.’ What will that day do for you?
