Isaiah Chapter 40
The first part of that which might be called the second book of Isaiah extends from chapter 40 to the end of chapter 48. The Messiah is, comparatively speaking, but little introduced here. It is rather the great question between Jehovah and idols, answered first by the success of Cyrus and the capture of Babylon. For, though their glory cannot be separated, there is Jehovah and His anointed. This is evidently connected in grace with the deliverance of Israel, God's witness on the earth, unworthy, as the nation was, to be so. At the same time these ways of God shewed that there was no peace at all for the wicked in Israel. This great truth is repeated twice over, being applied to the two great controversies which God had with Israel. We will point out some details to make all this evident. The first eight Verses of chapter 40 (Isa 40:1-8) express in a very remarkable manner the principles on which God acts: the grace flowing from His own heart, when His chastisements had been fully inflicted. God would comfort His people; and He speaks to the heart of Jerusalem, by telling her that her warfare is accomplished. The herald proclaims the coming of Jehovah. And here it is the fact, as deliverance: His rejection is not mentioned. It is spoken of later in chapters 51, 53. But with respect to the people, what must the prophet say? "All flesh is grass." If all flesh is to see the glory of Jehovah, if He pleads in vengeance with all flesh, this is where the testimony must begin. All flesh is grass: Jehovah bloweth upon it. Is it thus with the Gentiles only? No; "the people is grass." Comfort must begin with this. The grass withereth; who, then, can be trusted in? God has spoken. "The word of our God" (says the faith of the remnant-says the Spirit of prophecy) "shall stand for ever." Then comes the prophetic testimony to the blessedness of ransomed Zion, who proclaims to the cities of Judah the presence of Jehovah-the Saviour, whose tender care is then described in a touching manner. The glory of His divine Majesty is contrasted with idols to Verse 26 (Isa 40:26). He then challenges Israel for their unbelief. He who is Jehovah fainteth not, neither is weary. The depths of His wisdom are unsearchable; but they that wait on Him renew their strength, and shall not grow weary.
