40  The prophet having now foretold the Babylonish captivity, chap.Isa 39:6-7,
does here arm his people against it by the consideration of their certain deliverance out of it, and their blessed condition after it, as in other things so especially in the coming of the Messiah, and the great and glorious privileges conferred upon God's church and people in his days. The preaching of the gospel by John the baptist and the apostles, Isa 40:1-11.
The power and wisdom of God in governing the world, Isa 40:12-17.
The folly of idolatry, Isa 40:18-26.
God knows the state of his people, and both can and will protect them, Isa 40:27-31.

40:1 Ye - Ye prophets and ministers.

40:2 Warfare - The time of her captivity, and misery. Double - Not twice as much as her sins deserved, but abundantly enough to answer God's design in this chastisement, which was to humble and reform them, and to warn others by their example.

40:3 The voice - An abrupt speech. Methinks I hear a voice.Wilderness - This immediately relates to the deliverance of the Jews out of Babylon, and smoothing their passage from thence to Judea, which lay through a great wilderness; but principally to their redemption by the Messiah, whose coming was ushered in by the cry of John the baptist, in the wilderness. Prepare ye the way - You to whom this work belongs. He alludes to the custom of princes who send pioneers before them to prepare the way through which they are to pass. The meaning is, God shall by his spirit so dispose mens hearts, and by his providence so order the affairs of the world, as to make way for the accomplishment of his promise. This was eminently fulfilled, when Christ, who was, and is God, blessed for ever, came into the world in a visible manner.

40:6 Cry - God speaks unto his ministers. He - The prophet.All flesh - The prophet having foretold glorious things, confirms the certainty of them, by representing the vast difference between the nature, and word, and work of men and of God. All that men are or have, yea, their highest accomplishments, are but like the grass of the field, weak and vanishing, soon nipt and brought to nothing; but God's word is like himself, immutable and irresistible: and therefore as the mouth of the Lord, and not of man, hath spoken these things, so doubt not but they shall be fulfilled.

40:9  Zion - Zion or Jerusalem is the publisher, and thecities of Judah the hearers. Get up - That thy voice may be better heard. Afraid - Lest thou shouldest be found a false prophet. Say - To all my people in the several places of their abode. Behold - Take notice of this wonderful work, and glorious appearance of your God.

40:10 His arm - He shall need no succours, for his own power shall be sufficient to govern his people, and to destroy his adversaries.His reward - He comes furnished with recompences as well of blessings for his friends, as of vengeance for his enemies. His work - He carries on his work effectually: for that is said in scripture to be before a man which is in his power.

2:11 The saving grace of God - So it is in its nature, tendency, and design. Hath appeared to all men - High and low.

2:12 Instructing us - All who do not reject it. That, having renounced ungodliness - Whatever is contrary to the fear and love of God. And worldly desires - Which are opposite to sobriety and righteousness. We should live soberly - In all purity and holiness. Sobriety, in the scripture sense, is rather the whole temper of a man, than a single virtue in him.It comprehends all that is opposite to the drowsiness of sin, the folly of ignorance, the unholiness of disorderly passions.Sobriety is no less than all the powers of the soul being consistently and constantly awake, duly governed by heavenly prudence, and entirely conformable to holy affections. And righteously - Doing to all as we would they should do to us.And godly - As those who are consecrated to God both in heart and life.

2:13 Looking - With eager desire. For that glorious appearing - Which we hope for. Of the great God, even our Saviour Jesus Christ - So that, if there be (according to the Arian scheme) a great God and a little God, Christ is not the little God, but the great one.

2:14 Who gave himself for us - To die in our stead. That he might redeem us - Miserable bondslaves, as well from the power and the very being, as from the guilt, of all our sins.

3:4 When the love of God appeared - By the light of his Spirit to our inmost soul.

3:5 Not by works - In this important passage the apostle presents us with a delightful view of our redemption. Herein we have,

1. The cause of it; not our works or righteousness, but "the kindness and love of God our Saviour."
2. The effects; which are,
   1. Justification; "being justified," pardoned and acceptedthrough the alone merits of Christ, not from any desert in us, but according to his own mercy, "by his grace," his free, unmerited goodness.
   2. Sanctification, expressed by the laver of regeneration, (that is, baptism, the thing signified, as well as theoutward sign,) and the renewal of the Holy Ghost; which purifies the soul, as water cleanses the body, and renews it in the whole image of God.
3. The consummation of all; - that we might become heirs ofeternal life, and live now in the joyful hope of it.
