First the verse...
Hebrews 4:12
"For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart"
I will explain in a moment the rest...
You want Technical, so that's what I will provide.
WORD OF GOD
This is your DNA. It is the Book that God wrote, thus it is the Word of God...
Psalm 139:16
"Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them"
TWOEDGED SWORD
This is God giving you a metaphor or symbol for DNA.
Now... every time you see 'Twoedged Sword' in Scripture, you know God is referring to DNA.
Example:
Revelation 1:16
"And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength"
The Seven Stars (Seven Churches) refer to Nucleobases (Word of God). We are the Nucleobases of God's Body.
Seven is the Chemical Element Nitrogen.
The 'Stone With Seven Eyes' is also a Nucleobase.
This is why God will 'engrave' a new Genetic Sequence in it...
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"
Another example:
Proverbs 5:4
"But her end is bitter as wormwood, sharp as a twoedged sword"
Wormwood in this verse is referring to Phosphorus, the Chemical Element often related to Lucifer that makes up the *SERPENT* strands in our corrupt Human DNA.
Thus when John eats the 'Little Book' of DNA (remember... DNA is a Book)... the Deoxyribose is sweet, but the Phosphorus is bitter...
Revelation 10:10
"And I took the little book out of the angel’s hand, and ate it up; and it was in my mouth sweet as honey: and as soon as I had eaten it, my belly was bitter"
DIVIDING SOUL AND SPIRIT
If you haven't guessed already, DNA is where said takes place.
Spirit is the Nucleobases... the Word of God.
Soul is the Phosphorus (be wise as Serpents) where our ego and personality reside.
God has placed a division there.
When we die, God will separate the two while giving us our Glorified Bodies.
The Serpent gets replaced with the White Stone with a New Name (Gene Sequence) on it.
Any questions?
