"Quick" is a Middle English adjective for "living" (not the noun "life"). I don't see your stated union in this verse. That would be an allegorical interpretation to me.
Right, the living have life, as opposed to what I see in view here, which is physical death.
Again, the "soul" being the person, which is used primarily in regards to men who are still in their bodies (though we see "souls," persons in Heaven in Revelation), and the spirit being separated from their physical functionality.
This meaning is seen throughout Scripture. And I would just ask, don't you think knowing which (if one did embrace a trichotomy) is in view would be critical to understanding certain texts?
Secondly, I would just ask, what do you look at the statement that the Word of God is "living" as meaning? Would you consider John 1 an allegory?
The Greek word for "dividing asunder" is merismos, defined by the Friberg Analytical Lexicon: "as a process dividing up, division, separation." Thus, my translation would use the term "dividing point." The metaphor is a sharp, two-edged sword, which can pierce right down into the bone. So the metaphorical point is that there is within a human a place where the spirit and soul are joined together eternally. In other words, the spirit and soul, though one, are distinct. The Word of God brings conviction to the soul, and the spirit can thus be caused to live. (It is dead in a lost person.)
Hebrews 4:12
King James Version (KJV)
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.
Just pulling that back up to have the key verse in view.
I can't really give a physical context to the metaphor of the sword, because what is in view is spiritual, dealing with the inner man. It gives a picture represented with the concept of a sword being used to cut into a man, but that would be as far as I would go, seeing only "the joints and marrow" giving a glimpse of the physical body, and this in a state of death.
I have given the links for "joints and marrow" in the above verse. Best as I can make out, joints could be viewed as a reference to the body, and marrow (this word used only here in the New Testament and in Job 21:24 in the Septuagint) has, from my perspective, an implication of "that which is within." If this is the case, then again we see physical death and the separation of the spirit from the "person." Just take a look at these and the root for "marrow" and let me know what you think.
The Word of God brings conviction to the soul, and the spirit can thus be caused to live. (It is dead in a lost person.)
Exactly. Except instead of seeing "soul" as an inner aspect of man, I view it as the persons themselves, which doesn't come into conflict with this passage or any other.
"The Word of God brings conviction to the person, and he/she remains alive physically." As opposed to eternal judgment being in view for the spirit. Spirits do not die, but the soul can die (i.e., "Thy soul shall be required of thee this night). The penalty for violating the Word of God relevant to the Hebrews would have been physical death. Remission of sin was accomplished on a physical and temporal plane, men did not gain eternal life because they kept the Word of GOd, or if they offered up sacrifice for sin.
Okay, sorry for digging into this, just hoping you could give it a look and see what you think.
God bless.
