Isaiah 40:3-8

_ _ The time to favour Zion, yea, the set time, having come, the people of God must be prepared, by repentance and faith, for the favours designed them; and, in order to call them to both these, we have here the voice of one crying in the wilderness, which may be applied to those prophets who were with the captives in their wilderness-state, and who, when they saw the day of their deliverance dawn, called earnestly upon them to prepare for it, and assured them that all the difficulties which stood in the way of their deliverance should be got over. It is a good sign that mercy is preparing for us if we find God's grace preparing us for it, Psalms 10:17. But it must be applied to John the Baptist; for, though God was the speaker, he was the voice of one crying in the wilderness, and his business was to prepare the way of the Lord, to dispose men's minds for the reception and entertainment of the gospel of Christ. The way of the Lord is prepared,

_ _ I. By repentance for sin; that was it which John Baptist preached to all Judah and Jerusalem (Matthew 3:2, Matthew 3:5), and thereby made ready a people prepared for the Lord, Luke 1:17.

_ _ 1. The alarm is given; let all take notice of it at their peril; God is coming in a way of mercy, and we must prepare for him, Isaiah 40:3-5. If we apply it to their captivity, it may be taken as a promise that, whatever difficulties lie in their way, when they return they shall be removed. This voice in the wilderness (divine power going along with it) sets pioneers on work to level the roads. But it may be taken as a call to duty, and it is the same duty that we are called to, in preparation for Christ's entrance into our souls. (1.) We must get into such a frame of spirit as will dispose us to receive Christ and his gospel: “Prepare you the way of the Lord; prepare yourselves for him, and let all that be suppressed which would be an obstruction to his entrance. Make room for Christ: Make straight a highway for him.” If he prepare the end for us, we ought surely to prepare the way for him. Prepare for the Saviour; lift up your heads, O you gates! Psalms 24:7, Psalms 24:9. Prepare for the salvation, the great salvation, and other minor deliverances. Let us get to be fit for them, and then God will work them out. Let us not stand in our own light, nor put a bar in our own door, but find, or make, a highway for him, even in that which was desert ground. This is that for which he waits to be gracious. (2.) We must get our hearts levelled by divine grace. Those that are hindered from comfort in Christ by their dejections and despondencies are the valleys that must be exalted. Those that are hindered from comfort in Christ by a proud conceit of their own merit and worth are the mountains and hills that must be made low. Those that have entertained prejudices against the word and ways of God, that are untractable, and disposed to thwart and contradict even that which is plain and easy because it agrees not with their corrupt inclinations and secular interests, are the crooked that must be made straight and the rough places that must be made plain. Let but the gospel of Christ have a fair hearing, and it cannot fail of acceptance. This prepares the way of the Lord; and thus God will by his grace prepare his own way in all the vessels of mercy, whose hearts he opens as he did Lydia's.

_ _ 2. When this is done the glory of the Lord shall be revealed, Isaiah 40:5. (1.) When the captives are prepared for deliverance Cyrus shall proclaim it, and those shall have the benefit of it, and those only, whose hearts the Lord shall stir up with courage and resolution to break through the discouragements that lay in their way, and to make nothing of the hills, and valleys, and all the rough places. (2.) When John Baptist has for some time preached repentance, mortification, and reformation, and so made ready a people prepared for the Lord (Luke 1:17), then the Messiah himself shall be revealed in his glory, working miracles, which John did not, and by his grace, which is his glory, binding up and healing with consolations those whom John had wounded with convictions. And this revelation of divine glory shall be a light to lighten the Gentiles. All flesh shall see it together, and not the Jews only; they shall see and admire it, see it and bid it welcome; as the return out of captivity was taken notice of by the neighbouring nations, Psalms 126:2. And it shall be the accomplishment of the word of God, not one iota or tittle of which shall fall to the ground: The mouth of the Lord has spoken it, and therefore the hand of the Lord will effect it.

_ _ II. By confidence in the word of the Lord, and not in any creature. The mouth of the Lord having spoken it, the voice has this further to cry (he that has ears to hear let him hear it), The word of our God shall stand for ever, Isaiah 40:8.

_ _ 1. By this accomplishment of the prophecies and promises of salvation, and the performance of them to the utmost in due time, it appears that the word of the Lord is sure and what may be safely relied on. Then we are prepared for deliverance when we depend entirely upon the word of God, build our hopes on that, with an assurance that it will not make us ashamed: in a dependence upon this word we must be brought to own that all flesh is grass, withering and fading. (1.) The power of man, when it does appear against the deliverance, is not to be feared; for it shall be as grass before the word of the Lord: it shall wither and be trodden down. The insulting Babylonians, who promise themselves that the desolations of Jerusalem shall be perpetual, are but as grass which the spirit of the Lord blows upon, makes nothing of, but blasts all its glory; for the word of the Lord, which promises their deliverance, shall stand for ever, and it is not in the power of their enemies to hinder the execution of it. (2.) The power of man, when it would appear for the deliverance, is not to be trusted to; for it is but as grass in comparison with the word of the Lord, which is the only firm foundation for us to build our hope upon. When God is about to work salvation for his people he will take them off from depending upon creatures, and looking for it from hills and mountains. They shall fail them, and their expectations from them shall be frustrated: The Spirit of the Lord shall blow upon them; for God will have no creature to be a rival with him for the hope and confidence of his people; and, as it is his word only that shall stand for ever, so in that word only our faith must stand. When we are brought to this, then, and not till then, we are fit for mercy.

_ _ 2. The word of our God, that glory of the Lord which is now to be revealed, the gospel, and that grace which is brought with it to us and wrought by it in us, shall stand for ever; and this is the satisfaction of all believers, when they find all their creature-comforts withering and fading like grass. Thus the apostle applies it to the word which by the gospel is preached unto us, and which lives and abides for ever as the incorruptible seed by which we are born again, 1 Peter 1:23-25. To prepare the way of the Lord we must be convinced, (1.) Of the vanity of the creature, that all flesh is grass, weak and withering. We ourselves are so, and therefore cannot save ourselves; all our friends are so, and therefore are unable to save us. All the beauty of the creature, which might render it amiable, is but as the flower of grass, soon blasted, and therefore cannot recommend us to God and to his acceptance. We are dying creatures; all our comforts in this word are dying comforts, and therefore cannot be the felicity of our immortal souls. We must look further for a salvation, look further for a portion. (2.) Of the validity of the promise of God. We must be convinced that the word of the Lord can do that for us which all flesh cannot — that, forasmuch as it stands for ever, it will furnish us with a happiness that will run parallel with the duration of our souls, which must live for ever; for the things that are not seen, but must be believed, are eternal.
