Isaiah 40:5 Meaning and Commentary

Isaiah 40:5

And the glory of the Lord shall be revealed.
&c.] Christ himself, who is the brightness of his Father's glory, and his own glory, as the glory of the of the only begotten of the Father; the glorious perfections of his nature, seen in the miracles wrought, and in the doctrines taught by him; the glory of the divine Father, in the face or person of Christ; and the glory of his attributes, in the work of salvation by him; all which is most clearly discerned in the glass of the Gospel, or in the ministry of the word, by John, Christ himself, and his apostles: and all flesh shall see it together;
not the Jews only, but Gentiles also; not with their bodily eyes, but with the eyes of their understanding; even the salvation of the Lord, and his glory, as displayed in it, being set forth in the everlasting Gospel to the view of all; see ( Luke 3:7 ) , for the mouth of the Lord hath spoken it:
that his glory should be revealed, and be visible to all, and therefore sure and certain; for what he has said he does, and what he has spoken he makes good. The Targum is,

``for by the word of the Lord it is so decreed;''
and therefore shall be fulfilled.

Isaiah 40:5 In-Context

3 A voice of one crying out: Prepare the way of the Lord in the wilderness; make a straight highway for our God in the desert.
4 Every valley will be lifted up, and every mountain and hill will be leveled; the uneven ground will become smooth, and the rough places a plain.
5 And the glory of the Lord will appear, and all humanity will see [it] together, for the mouth of the Lord has spoken.
6 A voice was saying, "Cry out!" Another said, "What should I cry out?" "All humanity is grass, and all its goodness is like the flower of the field.
7 The grass withers, the flowers fade when the breath of the Lord blows on them; indeed, the people are grass.
