Isaiah, one of the most beloved and quoted prophets, speak to events of his own time, predicts events of our time, and sees to the end of days.
Isaiah 1, Rebellion of Judah
In the first four chapters, Isaiah writes of God's displeasure with the Southern Kingdom of Judah and its capitol, Jerusalem. In addition to speaking of Israel then, he speaks to us of our own situation.
Isaiah 1-2, The Process of Prophecy
In God's dealing with Israel, there is a definite process of prophecy. When Israel strays, the first message of the prophet is, "Repent." If they do repent, the process ends there and the prophet was successful. If not, the prophet begins speaking in parables, words of truth that will not be understood because exile is decreed. Finally Israel goes into exile at the hand of a gentile nation.
Isaiah 2-4, A Corrupt Society
Isaiah lists the details of why God is displeased with Judah and Jerusalem. This is a very sobering passage of Scripture; because, allowing for differences in language, every detail could be said of the United States today.
Isaiah 5, The Vineyard of the Lord
God describes Israel as a vineyard that has produced wild grapes instead of the useful ones He desired. In a lament, He asks what more He could have done to prevent this sad result. The answer being, 'Nothing,' He decides to remove His hand of protection and blessing. The lesson is that God will not continue to bless a nation that has become wicked.
Isaiah 6-7, Lest They Turn and Be Healed
Isaiah receives his commission directly from the Throne of God. He is told to speak to Israel in a way that they will not understand so that they will not turn from their wickedness and be healed. This teaches us that there can come a point where a nation has fallen so far that the only remedy is destruction and exile. In that event, God hides His face and speaks in parables.
Isaiah 8-9, Exile of the Northern Kingdom
Isaiah prophesies the exile of Israel by the Assyrians. He tells them that the Torah both predicts and explains what is about to happen. Once Israel abandons the Covenant and ignores the chastening God sends to get their attention, His Covenant specifies defeat and exile. In the midst of this gloom, He promises the Messiah.
Isaiah 9-10, God Keeps the Covenant
To understand what God was doing to the Northern Kingdom, they should have referred to Leviticus 26. There Moses describes how God would react if Israel does not walk according to the covenant. His chastening would be designed to get their attention and cause them to repent. If they didn't get the message, the intensity would increase up to the point of exile. This section also describes God's disposition of Assyria.
Isaiah 11-13, And a Little Child Shall Lead Them
The New Heaven and New Earth will be as God planned it in the Garden. Man will have dominion in peace instead of by force. This will be preceded by the destruction of Babylon and the salvation and reunification of Israel.
Isaiah 14, O Day Star, Son of the Dawn
Projecting the regathering of Israel, the prophet describes the ultimate disposition of Babylon. In this it becomes clear that the spiritual authority behind earthly Babylon is none other than Satan.
Isaiah 15-19, Destruction of Moab
Moab, named for one of the sons of Lot, is to be destroyed. This oracle explains that Moab's pride caused her to exacerbate the suffering of God's people during the time when Israel was being chastened by the Lord. Even though Israel's misery was caused by God, He judged the nations involved in that chastening when they engaged in 'unnecessary roughness' against His people.
Isaiah 18-20, Oracles of Cush and Egypt
Cush and Egypt were allies of Israel during the time of the Assyrian conquest. Since the Assyrians were God's chosen instrument, they proved insufficient. Also during these chapters we get a look forward to Apostolic times when peace would reign from Egypt to Syria.
