Isaiah is the first book of the prophets. The prophets are divided into two categories—major and minor—and Isaiah is considered one of the major prophets. The title of major prophet is given due to the length of the book, but if anyone deserves the title of major prophet, it's Isaiah. Quantity doesn't always mean quality, but in the case of the major prophets, especially Isaiah, the length of the book definitely correlates to the awesomeness of the prophecies given. I'm excited about jumping back in to Isaiah because, let's face it, prophecy is arguably the most important and exciting part of the Bible!

Both the New Testament and the book of Isaiah confirm Isaiah as the author. Isaiah prophesied in Israel from the reign of King Uzziah through King Hezekiah (Isaiah 1:1). Given this information, the book would have been written sometime between 701 and 681 BC.[5][6] This view was not contested by early Christians. In 1795, J.C. Doederlein began the trend of questioning Isaiah's authorship.[3] Isaiah's prophecies are so accurate, that to believe he is the author is to believe that he is a true prophet of God and God is truly divine. As such, non believing scholars are quick to follow in Doederlein's footsteps and do not believe Isaiah wrote the whole text.

Like the other books of the prophets, Isaiah contains accurate information about a time that occurs after the book is written. If someone predicted Donald Trump was going to be president during the presidential race, it wouldn't be be a big deal since the odds of being right were close to 50%. If they predicted he would win before he announced his decision to run, people may assume the person had insider information. A prediction that he would win the election before he was born would be much more impressive, right?

Isaiah foretold of Cyrus the Great, by name, and the decree he made for the Israelites to return to Israel 150 years before Cyrus made the decree.[2] This was before Israel was taken captive. Naturally, those who do not believe in the sovereign, all knowing power of God will say this is impossible. These scholars then decided there had to be at least 2 authors. The fact that the book naturally divides into two section lends to this argument. Supporters of multiple authors assert that Isaiah only wrote the first section, while other authors composed the rest of the text.

The New Testament confirms Isaiah as the author of the book of Isaiah (though often spelled with the Greek spelling Esaias in the KJV). In Matthew 3:3, Luke 3:4, and John 1:23, John the Baptist confirms Isaiah as the prophet who penned the book while pointing out the fulfillment of prophecy by Jesus. Matthew confirms Isaiah in Matthew 8:17 and 12:17-21. Paul attributes the book to Isaiah in Romans 9:27-33 and 10:16-21. John (the disciple) also attributes the book to Isaiah in John 12:38-41. Once you note that the verses these men reference are from all over Isaiah, not just in one section, it becomes clear that the those closest to Jesus agreed that Isaiah was the sole author of the book.

The Dead Sea Scrolls, which are the oldest manuscripts to be found to date, do not show any indication of Isaiah being two books or having multiple authors. This further confirms that early believers knew Isaiah to be sole author of the book.[3]

My Bible commentary (and many commentaries online) go into detail about several reasons to conclude that the book of Isaiah only has one author. The commentary points out the oddity that the identity poet who wrote the second half of Isaiah would be lost to history considering the skill and beauty of the text. If the Israelites could remember the names of the minor prophets, why wouldn't they preserve the name of this master poet? Furthermore, the style of the text shows Philistine influence and matches that of Isaiah's era, versus exhibiting Babylonian influence.

Overall, there really is no scientific reason to claim Isaiah isn't the author. As I said earlier, if scholars confirm Isaiah as the author, they would be confirming their belief in YHWH and Yeshua!

Isaiah tells us a lot about judgment and salvation. It is in the book of Isaiah that we learn how to identify the Messiah, which is important to Christians (and Jews) because this is how we know Jesus is who He says He is and not a deception from the devil. Isaiah also makes prophecies about the judgment of nations, including the captivity and release of Israel. He even prophesies about the end of the world! In short, I'd say Isaiah's purpose is to get us to open our eyes and pay attention.

Isaiah is often split into two sections: Isaiah 1-39 and Isaiah 40-66. The first section mirrors the Old Testament, while the second mirrors the New Testament. Even though the numbering of chapters was started only a few centuries ago and was not present in the original work, it is interesting that these sections also contain the same number of chapters as there are books in the testament it mirrors. While it is possible the editor who added the chapters could have done this of his own desire, the text still had to be structured in a way to make this possible.

On a website that lists 365 Messianic Prophecies, 132 of them are from the book of Isaiah![1] If you think of a prophecy that Jesus fulfilled, off the top of your head, there's a high probability that the prophecy is found in Isaiah, because most identifying prophecies of the Messiah come from the book of Isaiah (particularly Isaiah 53!).

The name Isaiah is Yesha'yahu in Hebrew, and it means Jehovah is salvation.[3][4] Not only does this phrase appear inside the book, but it also sums up the message Isaiah was given to share with us. I think of this when I need to remember that God creates us already knowing the plan He has for us!

It took me a year and a half to complete the posts for the book of Isaiah. In that time frame, I've actually read the book multiple times, going through each of the chapters over and over again. Isaiah is a very heavy book, and by heavy, I mean full of prophecy. As such, it's not a book to just plow through. In fact, from here on out, the rest of the Old Testament is solely prophetic books. That means it's crucial to research the history surrounding each passage. Some of the prophecies have already been fulfilled while others are in progress. This makes these books both extremely interesting and extremely challenging.

There were definitely times where I wanted to give up on Isaiah and move on to Jeremiah, but I knew that there was more information to be gleaned from these pages. What makes the Bible so difficult to understand is the need to understand all of it at once to understand individual verses. People love to quote a single verse, but it's easy to take things out of context and twist the meaning when we do that. As such, I found myself reading other parts of the Bible while I tried to digest Isaiah. Reading these other books and chapters helped me to stay grounded and keep the whole picture in mind.

Naturally, since it took me so long to complete the book, it's a little disjointed in my head. I watched the Bible Project's summary of the book once I finished to tie it all back together.[7]

Going in to the reading, I was looking forward to all the prophecy, specifically the Messianic prophecies. However, I found myself shocked to see that my favorite part was actually the passion in which Isaiah had for returning to God's original design. Many of us today fear the end of the world; we fear change, and we fear the loss of what we are used to. God never intended out world to be like this, but we can't conceive of a perfect utopia, because mankind can't create one; however, God can. After the judgement, there will be lasting peace and the world will return to a state of perfection (or rather there will be a new Earth that has never seen corruption).

Isaiah is eager to see this world come to fruition and encourages us to be eager to see this too. The only way to overcome the fear of change that keeps us from this is to admit our sinfulness, trust in God's promise to forgive us, and surrender to Him. When we do this continually, we too can become excited about the utopia God will create for us.

I didn't skip over the prophecy though. From prophecies about nations to prophecies about Christ, the book of Isaiah is loaded with prophecy. I looked far and wide for an exhaustive list of Messianic prophecies because I wanted to compare how many existed versus how many were in Isaiah. I couldn't find a list, mainly because people disagree about what actually is or isn't a prophecy. Nonetheless, below I'm going to list some of the Messianic prophecies I found. This list isn't exhaustive; I really should have been creating it as I go instead of remembering back. I'll continue to update it over time.
