If we apply this to the state of the Jews after their return out of captivity, it is a prophecy of the increase of their nation after they were settled in their own land. Jerusalem had been in the condition of a wife written childless, or a desolate solitary widow; but now it is promised that the city should be replenished and the country peopled again, that not only the ruins of Jerusalem should be repaired, but the suburbs of it extended on all sides and a great many buildings erected upon new foundations, - that those estates which had for many years been wrongfully held by the Babylonian Gentiles should now return to the right owners. God will again be a husband to them, and the reproach of their captivity, and the small number to which they were then reduced, shall be forgotten. And it is to be observed that, by virtue of the ancient promise made to Abraham of the increase of his seed, when they were restored to God's favour they multiplied greatly. Those that first came out of Babylon were but 42,000 (Ezr 2:64), about a fifteenth part of their number when they came out of Egypt; many came dropping to them afterwards, but we may suppose that to be the greatest number that ever came in a body; and yet above 500 years after, a little before their destruction by the Romans, a calculation was made by the number of the paschal lambs, and the lowest computation by that rule (allowing only ten to a lamb, whereas they might be twenty) made the nation to be nearly three millions. Josephus says, seven and twenty hundred thousand and odd, Jewish War 6.425. But we must apply it to the church of God in general; I mean the kingdom of God among men, God's city in the world, the children of God incorporated. Now observe, I. The low and languishing state of religion in the world for a long time before Christianity was brought in. It was like one barren, that did not bear, or travail with child, was like one desolate, that had lost husband and children; the church lay in a little compass, and brought forth little fruit. The Jews were indeed by profession married to God, but few proselytes were added to them, the rising generations were unpromising, and serious godliness manifestly lost ground among them. The Gentiles had less religion among them than the Jews; their proselytes were in a dispersion; and the children of God, like the children of a broken, reduced family, were scattered abroad (Joh 11:52), did not appear nor make any figure. II. Its recovery from this low condition by the preaching of the gospel and the planting of the Christian church. 1. Multitudes were converted from idols to the living God. Those were the church's children that were born again, were partakers of a new and divine nature, by the word. More were the children of the desolate than of the married wife; there were more good people found in the Gentile church (when that was set up) that had long been afar off, and without God in the world, than ever were found in the Jewish church. God's sealed ones out of the tribes of Israel are numbered (Rev 7:4), and they were but a remnant compared with the thousands of Israel; but those of other nations were so many, and crowded in so thickly, and lay so much scattered in all parts, that no man could number them, Isa 54:9. Sometimes more of the power of religion is found in those places and families that have made little show of it, and have enjoyed but little of the means of grace, than in others that have distinguished themselves by a flourishing profession; and then more are the children of the desolate, more the fruits of their righteousness, than those of the married wife; so the last shall be first. Now this is spoken of as matter of great rejoicing to the church, which is called upon to break forth into singing upon this account. The increase of the church is the joy of all its friends and strengthens their hands. The longer the church has lain desolate the greater will the transports of joy be when it begins to recover the ground it has lost and to gain more. Even in heaven, among the angels of God, there is an uncommon joy for a sinner that repents, much more for a nation that does so. If the barren fig-tree at length bring forth fruit, it is well; it shall rejoice, and others with it. 2. The bounds of the church were extended much further than ever before, Isa 54:2, Isa 54:3. (1.) It is here supposed that the present state of the church is a tabernacle state; it dwells in tents, like the heirs of promise of old (Heb 11:9); its dwelling is mean and movable, and of no strength against a storm. The city, the continuing city, is reserved for hereafter. A tent is soon taken down and shifted, so the candlestick of church privileges is soon removed out of its place (Rev 2:5), and, when God pleases, it is as soon fixed elsewhere. (2.) Though it be a tabernacle state, it is sometimes very remarkably a growing state; and, if this family increase, no matter though it be in a tent. Thus it was in the first preaching of the gospel; it was the business of the apostles to disciple all nations, to stretch forth the curtains of the church's habitation, to preach the gospel where Christ had not yet been named (Rom 15:20), to leaven with the gospel those towns and countries that had hitherto been strangers to it, and so to lengthen the cords of this tabernacle, that more might be enclosed, which would make it necessary to strengthen the stakes proportionably, that they might bear the weight of the enlarged curtains. The more numerous the church grows the more cautious she must be to fortify herself against errors and corruptions, and to support her seven pillars, Pro 9:1. (3.) It was a proof of divine power going along with the gospel that in all places it grew and prevailed mightily, Act 19:20. It broke forth, as the breaking forth of waters - on the right hand and on the left, that is, on all hands. The gospel spread itself into all parts of the world; there were eastern and western churches. The church's seed inherited the Gentiles, and the cities that had been desolate (that is, destitute of the knowledge and worship of the true God) came to be inhabited, that is, to have religion set up in them and the name of Christ professed. 3. This was the comfort and honour of the church (Isa 54:4): "Fear not, for thou shalt not be ashamed, as formerly, of the straitness of thy borders, and the fewness of thy children, which thy enemies upbraided thee with, but shalt forget the reproach of thy youth, because there shall be no more ground for that reproach." It was the reproach of the Christian religion, in its youth, that none of the rulers or princes of this world embraced it and that it was entertained and professed by a despicable handful of men; but, after awhile, nations were discipled, the empire became Christian, and then this reproach of its youth was forgotten. 4. This was owing to the relation in which God stood to his church, as her husband (Isa 54:5): Thy maker is thy husband. Believers are said to be married to Christ, that they may bring forth fruit unto God (Rom 7:4); so the church is married to him, that she may bear and bring up a holy seed to God, that shall be accounted to him for a generation. Jesus Christ is the church's Maker, by whom she is formed into a people - her Redeemer, by whom she is brought out of captivity, the bondage of sin, the worst of slaveries. This is he that espoused her to himself; and, (1.) He is the Lord of hosts, who has an irresistible power, an absolute sovereignty, and a universal dominion! Kings who are lords of some hosts, find there are others who are lords of other hosts, as many and mighty as theirs; but God is the Lord of all hosts. (2.) He is the Holy One of Israel, the same that presided in the affairs of the Old Testament church and was the Mediator of the covenant made with it. The promises made to the New Testament Israel are as rich and sure as those made to the Old Testament Israel; for he that is our Redeemer is the Holy One of Israel. (3.) He is and shall be called the Lord of the whole earth, as God, and as Mediator, for he is the heir of all things; but then he shall be called so, when the ends of the earth shall be made to see his salvation, when all the earth shall call him their God and have an interest in him. Long he had been called, in a peculiar manner, the God of Israel; but now, the partition wall between Jew and Gentile being taken down, he shall be called the God of the whole earth even where he has been, as at Athens itself, an unknown God.

The seasonable succour and relief which God sent to his captives in Babylon, when they had a discharge from their bondage there, are here foretold, as a type and figure of all those consolations of God which are treasured up for the church in general and all believers in particular, in the covenant of grace. I. Look back to former troubles, and in comparison with them God's favours to his people appear very comfortable, Isa 54:6-8. Observe, 1. How sorrowful the church's condition had been. She had been as a woman forsaken, whose husband was dead, or had fallen out with her, though she was a wife of youth, upon which account she is grieved in spirit, takes it very ill, frets, and grows melancholy upon it; or she had been as one refused and rejected, and therefore full of discontent. Note, Even those that are espoused to God may yet seem to be refused and forsaken, and may be grieved in spirit under the apprehensions of being so. Those that shall never be forsaken and left in despair may yet for a time be perplexed and in distress. The similitude is explained (Isa 54:7, Isa 54:8): For a small moment have I forsaken thee. In a little wrath I hid my face from thee. When God continues his people long in trouble he seems to forsake them; so their enemies construe it (Psa 71:11); so they themselves misinterpret it, Isa 49:14. When they are comfortless under their troubles, because their prayers and expectations are not answered, God hides his face from them, as if he regarded them not nor designed them any kindness. God owns that he had done this; for he keeps an account of the afflictions of his people, and, though he never turned his face against them (as against the wicked, Psa 34:16), he remembers how often he turned his back upon them. This arose indeed from his displeasure. It was in wrath that he forsook them and hid his face from them (Isa 57:17); yet it was but in a little wrath: not that God's wrath ever is a little thing, or to be made light of (Who knows the power of his anger?), but little in comparison with what they had deserved, and what others justly suffer, on whom the full vials of his wrath are poured out. He did not stir up all his wrath. But God's people, though they be sensible of ever so small a degree of God's displeasure, cannot but be grieved in spirit because of it. As for the continuance of it, it was but for a moment, a small moment; for God does not keep his anger against his people for ever; no, it is soon over. As he is slow to anger, so he is swift to show mercy. The afflictions of God's people, as they are light, so they are but for a moment, a cloud that presently blows over. 2. How sweet the returns of mercy would be to them when God should come and comfort them according to the time that he had afflicted them. God called them into covenant with himself when they were forsaken and grieved; he called them out of their afflictions when they were most pressing, Isa 54:6. God's anger endures for a moment, but he will gather his people when they think themselves neglected, will gather them out of their dispersions, that they may return in a body to their own land, - will gather them into his arms, to protect them, embrace them, and bear them up, - and will gather them at last to himself, will gather the wheat into the barn. He will have mercy on them. This supposes the turning away of his anger and the admitting of them again into his favour. God's gathering his people takes rise from his mercy, not any merit of others; and it is with great mercies (Isa 54:7), with everlasting kindness, Isa 54:8. The wrath is little, but the mercies are great; the wrath is for a moment, but the kindness everlasting. See how one is set over against the other, that we may neither despond under our afflictions nor despair of relief. II. Look forward to future dangers, and in defiance of them God's favours to his people appear very constant, and his kindness everlasting; for it is formed into a covenant, here called a covenant of peace, because it is founded in reconciliation and is inclusive of all good. Now, 1. This is as firm as the covenant of providence. It is as the waters of Noah, that is, as that promise which was made concerning the deluge that there should never be the like again to disturb the course of summer and winter, seed-time and harvest, Isa 54:9. God then contended with the world in great wrath, and for a full year, and yet at length returned in mercy, everlasting mercy; for he gave his word, which was as inviolable as his oath, that Noah's flood should never return, that he would never drown the world again; see Gen 8:21, Gen 8:22; Gen 9:11. And God has ever since kept his word, though the world has been very provoking; and he will keep it to the end; for the world that now is is reserved unto fire. And thus inviolable is the covenant of grace: I have sworn that I would not be wroth with thee, as I have been, and rebuke thee, as I have done. He will not be so angry with them as to cast them off and break his covenant with them (Psa 89:34), nor rebuke them as he has rebuked the heathen, to destroy them, and put out their name for ever and ever, Psa 9:5. 2. It is more firm than the strongest parts of the visible creation (Isa 54:10): The mountains shall depart, which are called everlasting mountains, and the hills be removed, though they are called perpetual hills, Hab 3:6. Sooner shall they remove than God's covenant with his people be broken. Mountains have sometimes been shaken by earthquakes, and removed; but the promises of God were never broken by the shock of any event. The day will come when all the mountains shall depart and all the hills be removed, not only the tops of them covered, as they were by the waters of Noah, but the roots of them torn up; for the earth and all the works that are therein shall be burned up; but then the covenant of peace between God and believers shall continue in the everlasting bliss of all those who are the children of that covenant. Mountains and hills signify great men, men of bulk and figure. Do these mountains seem to support the skies (as Atlas) and bear them up? They shall depart and be removed. Creature-confidences shall fail us. In vain is salvation hoped for from those hills and mountains. But the firmament is firm, and answers to its name, when those who seem to prop it are gone. When our friends fail us our God does not, nor does his kindness depart? Do these mountains threaten, and seem to top the skies, and bid defiance to them, as Pelion and Ossa? Do the kings of the earth, and the rulers, set themselves against the Lord? They shall depart and be removed. Great mountains, that stand in the way of the salvation of the church, shall be made plain (Zac 4:7); but God's kindness shall never depart from his people, for whom he loves he loves to the end; nor shall the covenant of his peace ever be removed, for he is the Lord that has mercy on his people. Therefore the covenant is immovable and inviolable, because it is built not on our merit, which is a mutable uncertain thing, but on God's mercy, which is from everlasting to everlasting.
