I found your insights interesting. I especially never took notice that the word "her" is applied to the tree of life.
I will however, attempt to show that this tree of life is Jesus dispensed into man.
And so the Bride of Christ which certainly is a "her". A vine tree circulating around and around the spiral street and
spiral river appropriately would be Christ imparted and dispensed into man. He is the true vine and we are the branches in John 15.
DNA forms a type of spiral or helix. If we use the Kingdom of God Within method of interpretation, (i.e., biology, human physiology, anatomy, etc.) the text will reveal even more. Much of the symbolism of Jesus in the Bible points to 'Seed', or to be blunt, Male Sperm. For example:
Galatians 3:16
"Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ."
What is Seed? A Child? Perhaps. However, there is another interpretation...
Luke 8:11
"Now the parable is this: The seed is the word of God."
The Word of God as Seed is synonymous to our modern concept of 'DNA'. The Word of God becomes DNA, then proteins, then flesh, etc...
John 1:14
"And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth."
Thus, Jesus as a 'Vine' is basically teaching that Jesus is the DNA template that the Redeemed will be grafted into. Grafting is a picture of Gene Splicing...
Romans 11:23
"And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again."
New Jerusalem is symbolic of the womb that our DNA will be graffed into. The Pillar you referenced earlier is also a symbolic of a Genome.
If we wish to be even more specific, the 'Branches' represent individual Nitrogen Bases as we see in the Candlestick which represents Mitochondrial DNA...
Thus, each person represents an individual letter in the Genome of God. The letters form the members of the Body just like DNA does...
1 Corinthians 12:19-20
"And if they were all one member, where were the body? But now are they many members, yet but one body."
The 'Lamb' represents a Nitrogen Base (i.e., Seed/Word of God). The Seven Eyes represent the seven Electrons of Nitrogen. One day a new 'engraving' or Gene Sequence will be written on the Nucleobase...
Zechariah 3:9
"For behold the stone that I have laid before Joshua; upon one stone shall be seven eyes: behold, I will engrave the graving thereof, saith the LORD of hosts, and I will remove the iniquity of that land in one day."
In other words, Sin will be removed from the Soul i.e., Genome.
I want to reserve comment on "HER fruit" until further study.
Sure, I get that. However, if we were to keep comparing New Jerusalem to a womb, we would discover that at some point they match up far too well to be a coincidence.
For example, Hagar represents Earthly Jerusalem...
Galatians 4:25 (New International Version)
"Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children."
In other words, God is linking the womb of an Earthly Mother to Earthly Jerusalem. The 'Temple' in Jerusalem is the Zygote inside of her...
The Tabernacles and Temples are scale models of Eukaryotic Cells. We are clothed with the Tabernacle. Does this make sense? Think of Mystery Babylon giving birth to harlots and abominations. It is a Biology issue.
The womb of Sarah gives birth to Children of Promise...
Galatians 4:31
"So then, brethren, we are not children of the bondwoman, but of the free."
See? We must be Born Again through Sarah as well as Abraham.
Look at the so called 'Pearly Gates'...
Revelation 21:21
"And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass."
What is the Gate? It is the
Gate of the Womb. Look...
Job 3:10 (Brenton Septuagint Translation)
"Because it shut not up the gates of my mother's womb, for so it would have removed sorrow from my eyes."
Job 38:8 (Brenton Septuagint Translation)
"And I shut up the sea with gates, when it rushed out, coming forth out its mother's womb."
Think Sea of People. The Gates are euphemism for the Vulva. Sorry to be so blunt.
We would normally think if the Bridegroom and the Bride as the pair.
Christ being the Bridegroom and the church being His Bride.
This is still true but Rev. 22:17 emphasis that the Bridegroom Jesus is the indwelling Spirit dispensed into the church.
The Marriage in Heaven is different than here on Earth. They do not work the same way. The Marriage in Heaven is the Seed fertilizing the Fruit. In other words, it is Conception between Sperm and Ovum, not marriage between two adult humans.
The Redeemed represent the Spirit that enters the Zygote upon Conception. During the Rapture, the Redeemed 'float' because they are not clothed with their final Tabernacle yet. It is like caterpillar vs. butterfly. The process is not complete at that stage.
Therefore the climax of this...
Yes, the Bride and Groom must consummate the marriage...
"In many traditions and statutes of civil or religious law, the consummation of a marriage, often called simply consummation, is the first (or first officially credited) act of sexual intercourse between two people, following their marriage to each other."
en.wikipedia.org
Again, Conception in Heaven is different. It is a 'Gene Splicing' event rather than a sex act.
We can see that if the tree of life grows along either side of the river of life it must be a spreading vine.
Ovary are on each side of the Birth Canal...
The leaves of the tree for the healing of the nations must be the behavior, deeds, acts of the sons of God
which are to be a healing of the nations.
The Leaves represent the new 'Covering', opposite of the Covering Adam and Eve tried to clothe themselves with...
Genesis 3:7
"And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons."
God eventually clothed the couple with the skin and flesh we have now...
Job 10:11
"Thou hast clothed me with skin and flesh, and hast fenced me with bones and sinews."
New Jerusalem is where the Redeemed get their final clothing.
