The book of Isaiah maps out the completeness of the Bible.
Isaiah contains 66 chapters, and the Bible has 66 books.
Isaiah has a notable break after 39 chapters (and 27 chapters follow), and the Bible breaks after 39 books, by ending the Old Testament (39 books) and beginning the New Testament (27 books).
Isaiah’s first 39 chapters focus on judgement, while the last 27 chapters focus on salvation.
(And note that the name Isaiah means Salvation of the Lord.)
Salvation appears as we start the last 27 chapters in Isaiah (4 chapters: Isaiah 40 to Isaiah 43).
These 4 chapters relate to the 4 Gospel books (Matthew, Mark, Luke and John) in the start of the New Testament (first 4 of 27 books).
For example, regarding John the Baptist, Isaiah 40 parallels to the 40th to 43rd Bible books: Matthew, Mark, Luke and John.
Isaiah 40:3
The voice of him that crieth in the wilderness, Prepare ye the way of the LORD, make straight in the desert a highway for our God.
Matthew 3:3
For this is he that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
Mark 1:3
The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
Luke 3:4
As it is written in the book of the words of Esaias the prophet, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
John 1:23
He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias.
(Esaias is a translation of the name: Isaiah.)
Similarly, ‘Carpenter’ parallels in Isaiah 41 and the Gospel.
Isaiah 41:7
So the carpenter encouraged the goldsmith, and he that smootheth with the hammer him that smote the anvil, saying, It is ready for the sodering: and he fastened it with nails, that it should not be moved.
Mark 6:3
Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon?
Also, the redeemer:
Isaiah 43:14
Thus saith the LORD, your redeemer, the Holy One of Israel;
Luke 24:21
But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done.
A cloud by day and fire by night reflects the fourth book: Numbers.
Isaiah 4:5
And the LORD will create upon every dwelling place of mount Zion, and upon her assemblies, a cloud and smoke by day, and the shining of a flaming fire by night: for upon all the glory shall be a defence.
Numbers 9:15-22
And on the day that the tabernacle was reared up the cloud covered the tabernacle, namely, the tent of the testimony: and at even there was upon the tabernacle as it were the appearance of fire, until the morning.
So it was alway: the cloud covered it by day, and the appearance of fire by night.
And when the cloud was taken up from the tabernacle, then after that the children of Israel journeyed: and in the place where the cloud abode, there the children of Israel pitched their tents.
At the commandment of the LORD the children of Israel journeyed, and at the commandment of the LORD they pitched: as long as the cloud abode upon the tabernacle they rested in their tents.
And when the cloud tarried long upon the tabernacle many days, then the children of Israel kept the charge of the LORD, and journeyed not.
And so it was, when the cloud was a few days upon the tabernacle; according to the commandment of the LORD they abode in their tents, and according to the commandment of the LORD they journeyed.
And so it was, when the cloud abode from even unto the morning, and that the cloud was taken up in the morning, then they journeyed: whether it was by day or by night that the cloud was taken up, they journeyed.
Or whether it were two days, or a month, or a year, that the cloud tarried upon the tabernacle, remaining thereon, the children of Israel abode in their tents, and journeyed not: but when it was taken up, they journeyed.
A shaving razor relates to Samson in the book of Judges, the seventh book.
Isaiah 7:20
In the same day shall the Lord shave with a razor that is hired, namely, by them beyond the river, by the king of Assyria, the head, and the hair of the feet: and it shall also consume the beard.
Judges 13:5
For, lo, thou shalt conceive, and bear a son; and no razor shall come on his head: for the child shall be a Nazarite unto God from the womb: and he shall begin to deliver Israel out of the hand of the Philistines.
Dusty dry bones rising for resurrection is featured in the twenty-sixth book: Ezekiel.
Isaiah 26:19
Thy dead men shall live, together with my dead body shall they arise. Awake and sing, ye that dwell in dust: for thy dew is as the dew of herbs, and the earth shall cast out the dead.
Ezekiel 37:1-10
The hand of the LORD was upon me, and carried me out in the spirit of the LORD, and set me down in the midst of the valley which was full of bones,
And caused me to pass by them round about: and, behold, there were very many in the open valley; and, lo, they were very dry.
And he said unto me, Son of man, can these bones live? And I answered, O Lord GOD, thou knowest.
Again he said unto me, Prophesy upon these bones, and say unto them, O ye dry bones, hear the word of the LORD.
Thus saith the Lord GOD unto these bones; Behold, I will cause breath to enter into you, and ye shall live:
And I will lay sinews upon you, and will bring up flesh upon you, and cover you with skin, and put breath in you, and ye shall live; and ye shall know that I am the LORD.
So I prophesied as I was commanded: and as I prophesied, there was a noise, and behold a shaking, and the bones came together, bone to his bone.
And when I beheld, lo, the sinews and the flesh came up upon them, and the skin covered them above: but there was no breath in them.
Then said he unto me, Prophesy unto the wind, prophesy, son of man, and say to the wind, Thus saith the Lord GOD; Come from the four winds, O breath, and breathe upon these slain, that they may live.
So I prophesied as he commanded me, and the breath came into them, and they lived, and stood up upon their feet, an exceeding great army.
At the end of Isaiah and the Bible, we have the completion of salvation:
Isaiah 66:7
Before she travailed, she brought forth; before her pain came, she was delivered of a man child.
Isaiah 66:22
For as the new heavens and the new earth, which I will make, shall remain before me, saith the LORD, so shall your seed and your name remain.
66th Bible book:
Revelation 12:1-2,5
And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
And she being with child cried, travailing in birth, and pained to be delivered.
…And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.
Revelation 21:1
And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
However, Isaiah’s last 27 chapters, (chapters 40 through 66) fall into 3 groups of 9 – that is: chapters 40 to 48, 49 to 57, and 58 to 66. At the end of each group of 9 chapters is a specific warning of God’s judgement on the wicked.
The first group of 9 (chapters 40 to 48) is about the salvation of Israel from the nations around it.
The second group of 9 (chapters 49 to 57) is about the salvation of people personally and individually.
The third group of 9 (chapters 58 to 66) is about the salvation of the whole earth – a new heaven and a new earth.
Regarding personal salvation – the middle of set of 9 is: chapters 49 to 57.
And what lies in the center of chapter 49 to 57? – the middle verse 53 – which is the central truth of the New Testament, Christ himself, predicted in the Old Testament.
And, if you note that the last 3 verses of chapter 52 are an introduction to the 12 verses of chapter 53, you can then look at the middle of these 15 verses.
The middle is Isaiah 53:4-6. This is the center of the revelation of the New Testament.
Isaiah 53:4-6
Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.
But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.
