Chapters 40 through 66 focus on the coming Messiah Jesus. In him we have comfort. Comfort is to speak to ones heart.
2 Cor 1:3 Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort;
2 Cor 1:4 Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God.
2 Cor 1:5 For as the sufferings of Christ abound in us, so our consolation also aboundeth by Christ.
Isa 40:2 Speak ye comfortably to Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned: for she hath received of the Lord's hand double for all her sins.
Jesus has won the victory for us. Our iniquity is pardoned, by faith in Jesus our sins are forgiven. Jerusalem and the people of faith, have received double for all her sins. I think of forgiveness and mercy, but still more we are made eternal sons and daughters of God. Jesus has given himself as our sacrifice for sin and is also our Great High Priest. He is our propitiation: the giving of his human life and the giver of Spiritual life, He is the sacrifice and the Holy place of forgiveness.
Rom 8:37 Nay, in all these things we are more than conquerors through him that loved us.
1 John 5:4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
Isa 40:3 The voice of him that crieth in the wilderness, Prepare ye the way of the LORD, make straight in the desert a highway for our God.

Isa 40:5 And the glory of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD hath spoken it.
John the Baptist had the Spirit of Isaiah when he repeated this verse.
John 1:23 He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias.
John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
The real preparation must take place in our hearts. Hearts must prepare to receive the coming of the Lord. The message of John was of repentance.
Isa 40:6 The voice said, Cry. And he said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field:
Isa 40:7 The grass withereth, the flower fadeth: because the spirit of the LORD bloweth upon it: surely the people is grass.
Isa 40:8 The grass withereth, the flower fadeth: but the word of our God shall stand for ever.
The message of the prophet is that man's life is as the grass , he will grow in his time and soon fade away. The flesh man will perish and should not be glorified. We are to glorify that which is eternal: the word of God shall stand forever.
Isa 40:9 O Zion, that bringest good tidings, get thee up into the high mountain; O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid; say unto the cities of Judah, Behold your God!

Isa 40:19 The workman melteth a graven image, and the goldsmith spreadeth it over with gold, and casteth silver chains.

Isa 40:22 It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:

The Lord made everything and he can take it away.

Rom 8:11 But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
To wait on the LORD is to actively seek Him. We wait until His power and direction is given to us. We mount up with wings as eagles, above the concerns of this life. We peacefully soar in the Spirit with the LORD. He takes us above the concerns of this life into heavenly places.
Eph 2:5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)

Gal 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
