401 Comfort, comfort my people, says your God. 2 Speak tenderly to Jerusalem, and cry to her that her warfare[1] is ended, that her iniquity is pardoned, that she has received from the Lord's hand double for all her sins.
3 A voice cries:[2] "In the wilderness prepare the way of the Lord; make straight in the desert a highway for our God. 4 Every valley shall be lifted up, and every mountain and hill be made low; the uneven ground shall become level, and the rough places a plain. 5 And the glory of the Lord shall be revealed, and all flesh shall see it together, for the mouth of the Lord has spoken." 6 A voice says, "Cry!" And I said[3], "What shall I cry?" All flesh is grass, and all its beauty[4] is like the flower of the field. 7 The grass withers, the flower fades when the breath of the Lord blows on it; surely the people are grass. 8 The grass withers, the flower fades, but the word of our God will stand forever.
9 Get you up to a high mountain, O Zion, herald of good news;[5] lift up your voice with strength, O Jerusalem, herald of good news;[6] lift it up, fear not; say to the cities of Judah, "Behold your God!" 10 Behold, the Lord GOD comes with might, and his arm rules for him; behold, his reward is with him, and his recompense before him.

Commentary on Isaiah 40:1-11
(Read Isaiah 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.
