1 The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem.   2 And it shall come to pass in the last days, that the mountain of the LORD's house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.   3 And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem.   4 And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning-hooks: nation shall not lift up sword against nation, neither shall they learn war any more.   5 O house of Jacob, come ye, and let us walk in the light of the LORD.

      The particular title of this sermon (v. 1) is the same with the general title of the book (ch. i. 1), only that what is there called the vision is here called the word which Isaiah saw (or the matter, or thing, which he saw), the truth of which he had as full an assurance of in his own mind as if he had seen it with his bodily eyes. Or this word was brought to him in a vision; something he saw when he received this message from God. John turned to see the voice that spoke with him. Rev. i. 12.

      This sermon begins with the prophecy relating to the last days, the days of the Messiah, when his kingdom should be set up in the world, at the latter end of the Mosaic economy. In the last days of the earthly Jerusalem, just before the destruction of it, this heavenly Jerusalem should be erected, Heb. xii. 22; Gal. iv. 26. Note, Gospel times are the last days. For 1. They were long in coming, were a great while waited for by the Old-Testament saints, and came at last. 2. We are not to look for any dispensation of divine grace but what we have in the gospel, Gal. i. 8, 9. 3. We are to look for the second coming of Jesus Christ at the end of time, as the Old-Testament saints did for his first coming; this is the last time, 1 John ii. 18.

      Now the prophet here foretels,

      I. The setting up of the Christian church, and the planting of the Christian religion, in the world. Christianity shall then be the mountain of the Lord's house; where that is professed God will grant his presence, receive his people's homage, and grant instruction and blessing, as he did of old in the temple of Mount Zion. The gospel church, incorporated by Christ's charter, shall then be the rendezvous of all the spiritual seed of Abraham. Now it is here promised, I. That Christianity shall be openly preached and professed; it shall be prepared (so the margin reads it) in the top of the mountains, in the view and hearing of all. Hence Christ's disciples are compared to a city on a hill, which cannot be hid, Matt. v. 14. They had many eyes upon them. Christ himself spoke openly to the world, John xviii. 20. What the apostles did was not done in a corner, Acts xxvi. 26. It was the lighting of a beacon, the setting up of a standard. Its being every where spoken against supposes that it was every where spoken of. 2. That is shall be firmly fixed and rooted; it shall be established on the top of the everlasting mountains, built upon a rock, so that the gates of hell shall not prevail against it, unless they could pluck up mountains by the roots. He that dwells safely is said to dwell on high, ch. xxxiii. 16. The Lord has founded the gospel Zion. 3. That it shall not only overcome all opposition, but overtop all competition; it shall be exalted above the hills. This wisdom of God in a mystery shall outshine all the wisdom of this world, all its philosophy and all its politics. The spiritual worship which it shall introduce shall put down the idolatries of the heathen; and all other institutions in religion shall appear mean and despicable in comparison with this. See Ps. lxvi. 16. Why leap ye, ye high hills? This is the hill which God desires to dwell in.

      II. The bringing of the Gentiles into it. 1. The nations shall be admitted into it, even the uncircumcised, who were forbidden to come into the courts of the temple at Jerusalem. The partition wall, which kept them out, kept them off, shall be taken down. 2. All nations shall flow into it; having liberty of access, they shall improve their liberty, and multitudes shall embrace the Christian faith. They shall flow into it, as streams of water, which denotes the abundance of converts that the gospel should make and their speed and cheerfulness in coming into the church. They shall not be forced into it, but shall naturally flow into it. Thy people shall be willing, all volunteers, Ps. cx. 3. To Christ shall the gathering of the people be, Gen. xlix. 10. See ch. lx. 4, 5.

      III. The mutual assistance and encouragement which this confluence of converts shall give to one another. Their pious affections and resolutions shall be so intermixed that they shall come in in one full stream. As, when the Jews from all parts of the country went up thrice a year to worship at Jerusalem, they called on their friends in the road and excited them to go along with them, so shall many of the Gentiles court their relations, friends, and neighbours, to join with them in embracing the Christian religion (v. 3): "Come, and let us go up to the mountain of the Lord; though it be uphill and against the heart, yet it is the mountain of the Lord, who will assist the assent of our souls towards him." Note, Those that are entering into covenant and communion with God themselves should bring as many as they can along with them; it becomes Christians to provoke one another to good works, and to further the communion of saints by inviting one another into it: not, "Do you go up to the mountain of the Lord, and pray for us, and we will stay at home;" nor, "We will go, and do you do as you will;" but, "Come, and let us go, let us go in concert, that we may strengthen one another's hands and support one another's reputation:" not, "We will consider of it, and advise about it, and go hereafter;" but, Come, and let us go forthwith. See Ps. cxxii. 1. Many shall say this. Those that have had it said to them shall say it to others. The gospel church is here called, not only the mountain of the Lord, but the house of the God of Jacob; for in it God's covenant with Jacob and his praying seed is kept up and has its accomplishment; for to us now, as unto them, he never said, Seek you me in vain, ch. xlv. 19. Now see here, 1. What they promise themselves in going up to the mountain of the Lord; There he will teach us of his ways. Note, God's ways are to be learned in his church, in communion with his people, and in the use of instituted ordinances--the ways of duty which he requires us to walk in, the ways of grace in which he walks towards us. It is God that teaches his people, by his word and Spirit. It is worth while to take pains to go up to his holy mountain to be taught his ways, and those who are willing to take that pains shall never find it labour in vain. Then shall we know if we follow on to know the Lord. 2. What they promise for themselves and one another: "If he will teach us his ways, we will walk in his paths; is he will let us know our duty, we will by his grace make conscience of doing it." Those who attend God's word with this humble resolution shall not be sent away without their lesson.

      IV. The means by which this shall be brought about: Out of Zion shall go forth the law, the New-Testament law, the law of Christ, as of old the law of Moses from Mount Sinai, even the word of the Lord from Jerusalem. The gospel is a law, a law of faith; it is the word of the Lord; it went forth from Zion, where the temple was built, and from Jerusalem. Christ himself began in Galilee, Matt. iv. 23; Luke xxiii. 5. But, when he commissioned his apostles to preach the gospel to all nations, he appointed them to begin in Jerusalem, Luke xxiv. 47. See Rom. xv. 19. Though most of them had their homes in Galilee, yet they must stay at Jerusalem, there to receive the promise of the Spirit, Acts i. 4. And in the temple on Mount Zion they preached the gospel, Acts v. 20. This honour was allowed to Jerusalem, even after Christ was crucified there, for the sake of what it had been. And it was by this gospel, which took rise from Jerusalem, that the gospel church was established on the top of the mountains. This was the rod of divine strength, that was sent forth out of Zion, Ps. cx. 2.

      V. The erecting of the kingdom of the Redeemer in the world: He shall judge among the nations. He whose word goes forth out of Zion shall by that word not only subdue souls to himself, but rule in them, v. 4. He shall, in wisdom and justice, order and overrule the affairs of the world for the good of his church, and rebuke and restrain those that oppose his interest. By his Spirit working on men's consciences he shall judge, and rebuke shall try men and check them; his kingdom is spiritual, and not of this world.

      VI. The great peace which should be the effect of the success of the gospel in the world (v. 4): They shall beat their swords into ploughshares; their instruments of war shall be converted into implements of husbandry; as, on the contrary, when war is proclaimed, ploughshares are beaten into swords, Joel iii. 10. Nations shall then not lift up sword against nation, as they now do, neither shall they learn war any more, for they shall have no more occasion for it. This does not make all war absolutely unlawful among Christians, nor is it a prophecy that in the days of the Messiah there shall be no wars. The Jews urge this against the Christians as an argument that Jesus is not the Messiah, because this promise is not fulfilled. But, 1. It was in part fulfilled in the peaceableness of the time in which Christ was born, when wars had in a great measure ceased, witness the taxing, Luke ii. 1. 2. The design and tendency of the gospel are to make peace and to slay all enmities. It has in it the most powerful obligations and inducements to peace; so that one might reasonably have expected it should have this effect, and it would have had it if it had not been for those lusts of men from which come wars and fightings. 3. Jew and Gentiles were reconciled and brought together by the gospel, and there were no more such wars between them as there had been; for they became one sheepfold under one shepherd. See Eph. ii. 15. 4. The gospel of Christ, as far as it prevails, disposes men to be peaceable, softens men's spirits, and sweetens them; and the love of Christ, shed abroad in the heart, constrains men to love one another. 5. The primitive Christians were famous for brotherly love; their very adversaries took notice of it. 6. We have reason to hope that this promise shall yet have a more full accomplishment in the latter times of the Christian church, when the Spirit shall be poured out more plentifully from on high. Then there shall be on earth peace. Who shall live when God doeth this? But do it he will in due time, for he is not a man that he should lie.

      Lastly, Here is a practical inference drawn from all this (v. 5): O house of Jacob! come you, and let us walk in the light of the Lord. By the house of Jacob is meant either, 1. Israel according to the flesh. Let them be provoked by this to a holy emulation, Rom. xi. 14. "Seeing the Gentiles are thus ready and resolved for God, thus forward to go up to the house of the Lord, let us stir up ourselves to go too. Let is never be said that the sinners of the Gentiles were better friends to the holy mountain than the house of Jacob." Thus the zeal of some should provoke many. Or, 2. Spiritual Israel, all that are brought to the God of Jacob. Shall there be such great knowledge in gospel times (v. 3) and such great peace (v. 4), and shall we share in these privileges? Come then, and let us live accordingly. What ever others do, come, O come! let us walk in the light of the Lord. (1.) Let us walk circumspectly in the light of this knowledge. Will God teach us his ways? Will he show us his glory in the face of Christ? Let us then walk as children of the light and of the day, Eph. v. 8; 1 Thess. v. 8; Rom. xiii. 12. (2.) Let us walk comfortably in the light of this peace. Shall there be no more war? Let us then go on our way rejoicing, and let this joy terminate in God, and be our strength, Neh. viii. 10. Thus shall we walk in the beams of the Sun of righteousness.

      4 Then the word of the LORD came unto me, saying,   5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.   6 Then said I, Ah, Lord GOD! behold, I cannot speak: for I am a child.   7 But the LORD said unto me, Say not, I am a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak.   8 Be not afraid of their faces: for I am with thee to deliver thee, saith the LORD.   9 Then the LORD put forth his hand, and touched my mouth. And the LORD said unto me, Behold, I have put my words in thy mouth.   10 See, I have this day set thee over the nations and over the kingdoms, to root out, and to pull down, and to destroy, and to throw down, to build, and to plant.

      Here is, I. Jeremiah's early designation to the work and office of a prophet, which God gives him notice of as a reason for his early application to that business (v. 4, 5): The word of the Lord came to him, with a satisfying assurance to himself that it was the word of the Lord and not a delusion; and God told him, 1. That he had ordained him a prophet to the nations, or against the nations, the nation of the Jews in the first place, who are now reckoned among the nations because they had learned their works and mingled with them in their idolatries, for otherwise they would not have been numbered with them, Num. xxiii. 9. Yet he was given to be a prophet, not to the Jews only, but to the neighbouring nations, to whom he was to send yokes (ch. xxvii. 2, 3) and whom he must make to drink of the cup of the Lord's anger, ch. xxv. 17. He is still in his writings a prophet to the nations (to our nation among the rest), to tell them what the national judgments are which may be expected for national sins. It would be well for the nations would they take Jeremiah for their prophet and attend to the warnings he gives them. 2. That before he was born, even in his eternal counsel, he had designed him to be so. Let him know that he who gave him his commission is the same that gave him his being, that formed him in the belly and brought him forth out of the womb, that therefore he was his rightful owner and might employ him and make use of him as he pleased, and that this commission was given him in pursuance of the purpose God had purposed in himself concerning him, before he was born: "I knew thee, and I sanctified thee," that is, "I determined that thou shouldst be a prophet and set thee apart for the office." Thus St. Paul says of himself that God had separated him from his mother's womb to be a Christian and an apostle, Gal. i. 15. Observe, (1.) The great Creator knows what use to make of every man before he makes him. He has made all for himself, and of the same lumps of clay designs a vessel of honour or dishonour, as he pleases, Rom. ix. 21. (2.) What God has designed men for he will call them to; for his purposes cannot be frustrated. Known unto God are all his own works beforehand, and his knowledge is infallible and his purpose unchangeable. (3.) There is a particular purpose and providence of God conversant about his prophets and ministers; they are by special counsel designed for their work, and what they are designed for they are fitted for: I that knew thee, sanctified thee. God destines them to it, and forms them for it, when he first forms the spirit of man within him. Propheta nascitur, non fit--Original endowment, not education, makes a prophet.

      II. His modestly declining this honourable employment, v. 6. Though God had predestinated him to it, yet it was news to him, and a mighty surprise, to hear that he should be a prophet to the nations. We know not what God intends us for, but he knows. One would have thought he would catch at it as a piece of preferment, for so it was; but he objects against it, as a work for which he is unqualified: "Ah, Lord God! behold, I cannot speak to great men and multitudes, as prophets must; I cannot speak finely nor fluently, cannot word things well, as a message from God should be worded; I cannot speak with any authority, nor can expect to be heeded, for I am a child and my youth will be despised." Note, It becomes us, when we have any service to do for God, to be afraid lest we mismanage it, and lest it suffer through our weakness and unfitness for it; it becomes us likewise to have low thoughts of ourselves and to be diffident of our own sufficiency. Those that are young should consider that they are so, should be afraid, as Elihu was, and not venture beyond their length.

      III. The assurance God graciously gave him that he would stand by him and carry him on in his work.

      1. Let him not object that he is a child; he shall be a prophet for all that (v. 7): "Say no any more, I am a child. It is true thou art; but," (1.) "Thou hast God's precept, and let not thy being young hinder thee from obeying it. Go to all to whom I shall send thee and speak whatsoever I command thee." Note, Though a sense of our own weakness and insufficiency should make us go humbly about our work, yet it should not make us draw back from it when God calls us to it. God was angry with Moses even for his modest excuses, Exod. iv. 14. (2.) "Thou hast God's presence, and let not thy being young discourage thee from depending upon it. Though thou art a child, thou shalt be enabled to go to all to whom I shall send thee, though they are ever so great and ever so many. And whatsoever I command thee thou shalt have judgment, memory, and language, wherewith to speak it as it should be spoken." Samuel delivered a message from God to Eli, when he was a little child. Note, God can, when he pleases, make children prophets, and ordain strength out of the mouth of babes and sucklings.

      2. Let him not object that he shall meet with many enemies and much opposition; God will be his protector (v. 8): "Be not afraid of their races; though they look big, and so think to outface thee and put thee out of countenance, yet be not afraid to speak to them; no, not to speak that to them which is most unpleasing. Thou speakest in the name of the King of kings, and by authority from him, and with that thou mayest face them down. Though they look angry, be not afraid of their displeasure nor disturbed with apprehensions of the consequences of it." Those that have messages to deliver from God must not be afraid of the face of man, Ezek. iii. 9. "And thou hast cause both to be bold and easy; for I am with thee, not only to assist thee in thy work, but to deliver thee out of the hands of the persecutors; and, if God be for thee, who can be against thee?" If God do not deliver his ministers from trouble, it is to the same effect if he support them under their trouble. Mr. Gataker well observes here, That earthly princes are not wont to go along with their ambassadors; but God goes along with those whom he sends, and is, by his powerful protection, at all times and in all places present with them; and with this they ought to animate themselves, Acts xviii. 10.

      3. Let him not object that he cannot speak as becomes him--God will enable him to speak.

      (1.) To speak intelligently, and as one that had acquaintance with God, v. 9. He having now a vision of the divine glory, the Lord put forth his hand, and by a sensible sign conferred upon him so much of the gift of the tongue as was necessary for him: He touched his mouth, and with that touch opened his lips, that his mouth should show forth God's praise, with that touch sweetly conveyed his words into his mouth, to be ready to him upon all occasions, so that he could never want words who was thus furnished by him that made man's mouth. God not only put knowledge into his head, but words into his mouth; for there are words which the Holy Ghost teaches, 1 Cor. ii. 13. It is fit God's message should be delivered in his own words, that it may be delivered accurately. Ezek. iii. 4, Speak with my words. And those that faithfully do so shall not want instructions as the case requires; God will give them a mouth and wisdom in that same hour, Matt. x. 19.

      (2.) To speak powerfully, and as one that had authority from God, v. 10. It is a strange commission that is here given him: See, I have this day set thee over the nations and over the kingdoms. This sounds very great, and yet Jeremiah is a poor despicable priest still; he is not set over the kingdoms as a prince to rule them by the sword, but as a prophet by the power of the word of God. Those that would hence prove the pope's supremacy over kings, and his authority to depose them and dispose of their kingdoms at his pleasure, must prove that he has the same extraordinary spirit of prophecy that Jeremiah had, else how can be have the power that Jeremiah had by virtue of that spirit? And yet the power that Jeremiah had (who, notwithstanding his power, lived in meanness and contempt, and under oppression) would not content these proud men. Jeremiah was set over the nations, the Jewish nation in the first place, and other nations, some great ones besides, against whom he prophesied; he was set over them, not to demand tribute from them nor to enrich himself with their spoils, but to root out, and pull down, and destroy, and yet withal to build and plant. [1.] He must attempt to reform the nations, to root out, and pull down, and destroy idolatry and other wickednesses among them, to extirpate those vicious habits and customs which had long taken root, to throw down the kingdom of sin, that religion and virtue might be planted and built among them. And, to the introducing and establishing of that which is good, it is necessary that that which is evil be removed. [2.] He must tell them that it would be well or ill with them according as they were, or were not, reformed. He must set before them life and death, good and evil, according to God's declaration of the method he takes with kingdoms and nations, ch. xviii. 9-10. He must assure those who persisted in their wickedness that they should be rooted out and destroyed, and those who repented that they should be built and planted. He was authorized to read the doom of nations, and God would ratify it and fulfil it (Isa. xliv. 26), would do it according to his word, and therefore is said to do it by his word. It is thus expressed partly to show how sure the word of prophecy is--it will as certainly be accomplished as if it were done already, and partly to put an honour upon the prophetic office and make it look truly great, that others may not despise the prophets nor they disparage themselves. And yet more honourable does the gospel ministry look, in that declarative power Christ gave his apostles to remit and retain sin (John xx. 23), to bind and loose, Matt. xviii. 18.
