OK, I'll go into what you cited. I usually think (and I thought the same of you) that people will get the idea of what is being said over and over. I didn't think I would have to repeat myself again and again. And JehovahsWitness has posted some excellent information, which I felt would clear up a lot. But the fog seems to remain.
You say that the terms "soul" and "spirit" considerably overlap. Of course they would, since a person's
impelling mental inclination (one aspect of the term "spirit"), which is the
force that causes a person to display a certain attitude or emotion, would be a part of what makes a person whole. It involves the person's mental processes---his thoughts and feelings---and
not a separate being inside that has consciousness of its own, which separates at death. It's purely brain activity---(nothing to do with an "immortal spirit" that lives on after death.) So in that way a person's spirit is part of the soul.
Do you see the difference? You say that a person has a separate spirit
body that "goes back to God," fully conscious, at death. The Scriptures tell us of a spirit within us that
has no consciousness but is (1)a FORCE that keeps us alive, and (2)our own mental inclinations that help make us who we are with our particular personality.
I'll go on and take your "overlapping" proof scriptures one by one.
SOUL = seat of emotions: (1) Genesis 42:21: "...we saw the
distress of his soul when he implored compassion on our part..." Is there anything there that contradicts what I explained above? The SOUL is the whole person. When the person is distressed, his whole self is involved. There is no need to think that there is another separate, conscious, spirit PERSON inside that is distressed. (2) Deuteronomy 28:65: "...Jehovah will indeed give you there a trembling heart and a failing of the eyes and
despair of soul." The same can be said in this instance. "Despair of soul" is a situation that the whole person finds himself in. There is NO INDICATION that he has a separate spirit person inside him that is conscious on its own and can leave when the physical person dies.
SPIRIT = seat of emotions (the "same as with the soul"): (1) Isaiah 19:14: "The LORD has mixed within her
a spirit of distortion; they have led Egypt astray in all that it does." This is referring to the counselors of Pharaoh who counsel unreasonable things. They have no knowledge of God and His purposes;
they are deceived and their thoughts are distorted. The "spirit of distortion," or, as the
New American Bible says, "a spirit of dizziness," which influences the counselors of Pharaoh, is one of two things....
but NOT a spirit within any person that would dictate to the person what he must think and which has a consciousness all of its own and can depart at death and go on living as that person. (Which, I think, is what you're trying to prove, right?) The two things that the verse might be referring to: (a) a spirit person, like an angel, who would make the already wayward and deceived counselors "dizzy" because of their lack of appreciation of the true God; or (b) the very influence of the "spirit of the authority of the air" (Ephesians 2:2), which is the impelling mental state of Satan that saturates everything in this world.
It is NOT a spirit person that is inside everybody and has a consciousness all of its own and separates at death, to go on living.
(2) Numbers 14:24: "As for my servant Caleb, because
a different spirit has proved to be with him and he kept following wholly after me..." Is this speaking of a spirit person---an angel---that was with Caleb? If that is so, it doesn't prove any of your arguments. Or do you think it is
Caleb's own mental inclination? That shows that what Caleb thought did indeed have an effect on his whole self, everything about him. There is no indication of a separate, conscious spirit body inside Caleb that would leave his body at death.
Along with this goes your next point: "The 'spirit' can denote innermost thoughts." I think we have discussed this thoroughly already here, but I'll comment once again, since I said I would take each of your verses. (1) Proverbs 16:20: (I think you may have meant 16:19) "Better it is to be of
an humble spirit with the lowly, than to divide the spoil with the proud" (KJV). Hello. A good example of
a person's own mental inclination---the force that causes a person to show a certain attitude or disposition. We've all said at one time or another about someone, "She is a mean-spirited person." Do we mean that she has a conscious, separate spirit body inside her that makes her mean? No. She is mean herself, with no separate scheming spirit making her do anything. We might speak of a person as "putting on airs," or of showing an "air of calmness," or of "having a depressed spirit." We speak of "breaking a person's spirit" in the sense of
discouraging and disheartening him. We may talk of "getting into the spirit of an occasion" (e.g., "the Christmas spirit"), or we may refer to the "mob spirit" that people get caught up in at times. These are not conscious spirit bodies that inhabit people and that leave at death. I'm sure you can see the difference.
(2) Mark 2:8: "Jesus, having
discerned immediately by his spirit that they were reasoning that way..." Once again, Jesus' "spirit" being the
mental inclination which he possessed, and only that. Were you trying to say that Jesus had a spirit body inside him that filled him in on what was going on? I can't wrap my mind around that idea. Is that what you mean? (3) John 11:33: "Jesus, therefore, when he saw her weeping and the Jews that came with her weeping,
groaned in the spirit and became troubled." Another example of Jesus' own mental inclination. He was a compassionate man. (4) I Corinthians 2:11: "For who among men knows the things of a man except
the spirit of man that is in him? So, too, no one has come to know the things of God, except
the spirit of God." Here we have another example of man's
mental inclinations. Humans' mental inclinations are on a different level than God's spirit. God's spirit is His
active force that accomplishes whatever He wishes to get done. It is a very powerful force....after all, Jehovah created the universe with His spirit (through, of course, His Son). There is no indication here that man has a conscious spirit person/body inhabiting his physical body that will separate at death.
You then say that "spirit can denote deep insights and wisdom; prophets have been moved by 'the spirit of wisdom.'" Numbers 11:17: "...I shall have to take away some of the
spirit that is upon you and place it upon them, and they will have to help you in carrying the load of the people..." This is Jehovah's own holy spirit that He caused to be on Moses, and He was about to give some of that spirit to the other men that Moses chose to help him.
I already commented on your statement that "the spirit returns to God who gave it." You didn't mention where it was to be found, but I know it is Ecclesiastes 12:7, and it is referring to
the life-force that keeps a soul alive. When a switch gets turned off in your house, and the light is no longer on, that force (current) is not some conscious being, but it simply isn't there any longer keeping the light on. The current, in a sense, "returned" to where it came from. "Spirit" and "soul" would not be interchangeable in that verse, would they?
You say that the "soul" is "said to be saved." Yes! People (souls) are in a position to be saved, by Jesus' ransom sacrifice. Psalm 116:14 doesn't say anything about a soul or being saved. Verse 13 speaks of "the cup of grand salvation I shall take up." Yes, we all want to be saved. 2 Samuel 4:9: "David answered Rechab and Baanah his brother...and said to them: 'As Jehovah
who redeemed my soul out of all distress is living....'" Again a verse that attributes to Jehovah the redemption of someone's "soul," or his whole person.
You have not shown that the "soul" and the "spirit" mean the same thing anywhere.
They can AFFECT one another, but they are not the same.
