Book-ends
Book-ends are those funny things that hold books upright on the shelf. They frame a series of books and keep them from falling over. When the books of the Bible are ordered based on Isaiah, book-ends appear around the Bible, the Testaments and the Gospels.
Bible Book-ends
At the edges of the Bible the book order is unaffected by Isaiah. Genesis still opens the Bible and Revelation is the close. However, there is a book-end that confirms these books are correctly placed.
Revelation ends with a couple references to the "Tree of Life."
66 Revelation 22:2
2In the middle of the great street of the city, and on either side of the river, was the tree of life, which bore 12 kinds of fruits, and each month, it yielded 1 of its fruits; and the leaves of the tree were for the healing of the peoples.
The Tree of Life first appears in the Garden of Eden, early in the book of Genesis.
1 Genesis 2:9
9And out of the ground Yahvah God made to grow every tree that is pleasant to the sight and good for food; also the tree of life in the middle of the garden, and the tree of the knowledge of good and evil.
The beauty of these references to the Tree of Life is their proximity. Revelation only appears far from Genesis until you realize the context at the end of Revelation continues at the start of Genesis.
Connecting the end of Revelation to the book of Genesis we realize the New Jerusalem is just another name for the Garden of Eden. Both places contain the Tree of Life and there's no story in the Bible about transplanting that tree. In the Genesis account we learn about our past fall from Eden and Revelation predicts our future restoration to Eden.
Testament Book-ends
Like the Bible the Old and New Testaments are framed with book-ends. Genesis and Daniel bracket the Old Testament. John and Revelation bracket the New Testament.
The Old Testament begins with the famous "In the beginning" verse.
1 Genesis 1:1
1In a beginning god created the skies and the land.
Daniel ends the Old Testament with a less famous but equally interesting reference to "The End."
39 Daniel 12:13
13But as for you, Daniel, go your way and rest until the end; then you will arise at your appointed time, at the end of the days.
The Old Testament is thus bracketed with the simple ideas of "beginning" and "end."
The New Testament is bracketed the same way as the Old. You are probably familiar with how the Gospel of John begins. It's an echo of Genesis 1:1.
40 John 1:1-3
1In the beginning was the word, and that very word was with god, and god was that word.
2The same was in the beginning with god.
3Everything came to be by his hand; and without him, not even one thing that was created, came to be.
And Revelation, like Daniel, ends with "the end."
66 Revelation 22:13
13I am Wa and Ta, the beginning and the end, the first and the last.
Revelation actually has more to say than just "the end." You may have noticed it mentions "the beginning" also. Why? It seems to be highlighting the high-level structure of the Bible. It has at least three words related to "beginning" and three related to "end." We haven't looked at the Gospel Book-ends yet, but Revelation appears to be summing up all three sections, the Bible, Testaments, and Gospels, by mentioning three beginnings and three ends.
Gospel Book-ends
The order of the Gospels is John, Matthew, Mark and Luke. Placing John as the first book in the Gospel series makes plenty of sense. It's noteworthy how often people are advised to begin their Bible reading with the Gospel of John. Yet even the opening line of the book attests to the idea that John comes first. John begins in the beginning.
40 John 1:1
1In the beginning was the word, and that very word was with god, and god was that word.
When John is placed first in the Gospel series a type of book-ends form between the end of John and beginning of Luke. Look at this statement near the end of John with the thought that you are reading the books in order and Matthew, Mark and Luke come next.
40 John 20:30
30Many other miracles Jesus did in the presence of his disciples, which are not written in this book;
This statement refers to the things Jesus did in Matthew, Mark and Luke that are not recorded in John. It's consistent that a statement at the end of John would both separate John from the synoptic Gospels and prepare the reader to learn new things about Jesus in the following books.
Presumably we then read through Matthew and Mark before arriving at Luke. Luke then begins with a cryptic statement that references the preceeding Gospels. I'll quote the whole statement and then give some explanation verse by verse.
43 Luke 1:1-4
1Since many have desired to have in writing the story of those works with which we are familiar,
2according to what was handed down to us by those who, from the beginning, were eyewitnesses and ministers of that very word,
3and since these were also seen by me because I was near, and considered them all very carefully; I will therefore write to you everything in its order, most honorable Theophilus,
4so that you may know the truth of the words by which you were made a convert.
Verse 1
The "works" which we (the readers) are familiar are everything we've read in John, Matthew and Mark before getting to Luke.
Verse 2
The phrases "the beginning" and "the Word" in this verse harken back to the start of John. Remember, "In the beginning was the Word (John 1:1)." Those who knew Jesus "handed down their observations" in the forms of John, Matthew and Mark. (We're not necessarily establishing the historical development of the Gospels here, that's a separate question, but we are asserting their canonical reading order.)
Verse 3
Luke cares about "order" so the idea that Luke would reveal his position in the book order before beginning his "orderly" account is consistent. In essence I read this whole opening statement as Luke saying, You're familiar with Jesus because of the stuff that's been passed down starting with John. I want to add just one more account, an orderly one.
Verse 4
Verse 4 reveals that Luke is addressed to Theophilus. One benefit of moving John to the start of the Gospel series is Luke returns to his natural place next to Acts, which is also addressed to Theophilus.
44 Acts 1:1-4
1The first book I have written, Theophilus, concerning all the things which Master Jesus, an anointed, began to do and teach
2until the day when he ascended, after he, through the holy spirit, had given commandments to the apostles whom he had chosen,
3the very ones to whom he had also shown himself alive, after he had suffered, with many wonders during the 40 days, while appearing to them and talking with them concerning the kingdom of god.
4And as he ate bread with them, he commanded them not to depart from Jerusalem, but to wait for the promise of the father, The one of whom you have heard from me.
Conclusion
Each of the sections created by the book-ends is a series of related writings. The Bible is different from all other writings in the world. The Hebrew scriptures are distinguished from the Aramaic scriptures, though they work together wonderfully. The Gospels are also unique among the books of the Bible.
