40:1-11 All human life is a warfare; the Christian life is the most so; but the struggle will not last always. Troubles are removed in love, when sin is pardoned. In the great atonement of the death of Christ, the mercy of God is exercised to the glory of his justice. In Christ, and his sufferings, true penitents receive of the Lord's hand double for all their sins; for the satisfaction Christ made by his death was of infinite value. The prophet had some reference to the return of the Jews from Babylon. But this is a small event, compared with that pointed out by the Holy Ghost in the New Testament, when John the Baptist proclaimed the approach of Christ. When eastern princes marched through desert countries, ways were prepared for them, and hinderances removed. And may the Lord prepare our hearts by the teaching of his word and the convictions of his Spirit, that high and proud thoughts may be brought down, good desires planted, crooked and rugged tempers made straight and softened, and every hinderance removed, that we may be ready for his will on earth, and prepared for his heavenly kingdom. What are all that belongs to fallen man, or all that he does, but as the grass and the flower thereof! And what will all the titles and possessions of a dying sinner avail, when they leave him under condemnation! The word of the Lord can do that for us, which all flesh cannot. The glad tidings of the coming of Christ were to be sent forth to the ends of the earth. Satan is the strong man armed; but our Lord Jesus is stronger; and he shall proceed, and do all that he purposes. Christ is the good Shepherd; he shows tender care for young converts, weak believers, and those of a sorrowful spirit. By his word he requires no more service, and by his providence he inflicts no more trouble, than he will strengthen them for. May we know our Shepherd's voice, and follow him, proving ourselves his sheep.

Verse 6. - The voice said, Cry; rather, a voice of else that sayeth, Cry. It is a second voice, distinct from that of ver. 3, that now reaches the prophet's ear - a voice responded to by another. The speakers seem to be angels, who contrast the perishable nature of man with the enduringness and unchangingness of God. The point of their discourse is that "the Word of the Lord endureth for ever" (ver. 8), and therefore the preceding promises (vers. 2, 5) are sure. And he said; rather, and one said. A second voice answered the first, and asked what the proclamation was to be. In reply its terms were given. All flesh is grass (comp. Isaiah 37:27; and see also Job 5:25; Psalm 90:5; Psalm 92:7; Psalm 103:15). The goodliness thereof is as the flower of the field. So Ephraim was compared in ch. 28:1 to "a fading flower." The similitude is found also in Job 14:2 and in Psalm 103:15. Homer approaches the idea in his well-known simile, Οἵη περ φύλλων γενεὴ τοιήδε καὶ ἀνδρῶν ('Iliad,' 6:146).

The voice said, cry,.... Not the same voice as in Isaiah 40:3, nor the voice of an angel, as Aben Ezra; but a voice from the Lord, as Jarchi; the voice of prophecy, says Kimchi; it is the Lord's voice to the prophet, or rather to any and every Gospel minister, giving them an order to prophesy and preach, without which they cannot preach regularly and lawfully; it is the same as, "go, teach all nations", &c. preach the Gospel to every creature, &c. Matthew 28:19,

and he said, what shall I cry? publish, proclaim, or preach? for a minister of the Gospel is to preach not out of his own heart, or of his own head, or what is of his own devising and framing, but what is agreeable to the mind of Christ, as revealed in his word; he is to speak according to the oracles of God, the proportion and analogy of faith; he is to inquire there, and of Christ, what he shall say. The Targum is,

"the voice of him that saith, prophesy; and he answered and said, what shall I prophesy?''

The reply is,

all flesh is grass; declare the frailty and mortality of men; which some think is mentioned, to increase the wonder of Christ's incarnation, after prophesied of, as the forerunner of it is before; that Christ should condescend to take upon him such frail mortal flesh; that he should become flesh, and be manifested in it: or rather this is to be said, to put men in mind and to prepare them to think of another world, and how they shall appear before the judgment seat; seeing, if they have not a better righteousness than their own, and except they are born again, they shall neither see nor enter into the kingdom of heaven; which is one of the first things to be published in the Gospel ministry; as also how weak, impotent, and insufficient, men are, to that which is good, which may be meant by this phrase; being as weak as a spire of grass, not able to do any good actions, much less to fulfil the law, or to regenerate themselves, renew their hearts, or cleanse their natures: and this must be said, to abate the pride of men; to show the necessity of divine power in regeneration; to instruct men to seek for the grace of God, as to convert them, so to help and assist them in all they do; and to direct them to ascribe all they have, and are, to the grace of God; to this purpose the Apostle Peter quotes this passage, 1 Peter 1:23. It may be applied to the ordinances of the legal dispensation, and all the privileges of it, which are said to be carnal; and trusting in them was trusting in the flesh, Philippians 3:4, Hebrews 9:10, these were weak and insufficient to justify, sanctify, and save, and were not to continue:

and all the goodliness thereof is as the flower of the field; all the goodliness and glory of man; all that is excellent and valuable in him, or belonging to him, Or that is thought to be so, his riches, honours, strength, beauty, wisdom, and knowledge; yea, all his seeming holiness and righteousness; which are all fading and perishing, like a gay flower, which appears lovely for a while, and on a sudden falls off, or is cropped, or trampled upon; to which a flower of the field is more liable than that of the garden. This may be applied to the splendour of the legal dispensation, which is done away by a more excellent glory taking place, 2 Corinthians 3:10.

6. The voice—the same divine herald as in Isa 40:3.

he—one of those ministers or prophets (see on [778]Isa 40:1) whose duty it was, by direction of "the voice," to "comfort the Lord's afflicted people with the promises of brighter days."

All flesh is grass—The connection is, "All human things, however goodly, are transitory: God's promises alone steadfast" (Isa 40:8, 15, 17, 23, 24); this contrast was already suggested in Isa 40:5, "All flesh … the mouth of the Lord." 1Pe 1:24, 25 applies this passage distinctly to the gospel word of Messiah (compare Joh 12:24; Jas 1:10).
