Well, I argued from scripture that a "soul" results from the unification of body and spirit. Genesis 2:7 Consider other alloys or combinations of things, which result in something entirely new.
God created a soul to be eternal, not the mortal body given to Adam when Adam disobeyed God. Adam had a permanent incorruptible physical body that would have lived forever. That is the whole point. God took that permanent incorruptible physical body away and placed Adam's soul in a temporal corruptible physical body, which we define as mortal.
Adam was made subject to death, because he no longer had that permanent incorruptible physical body. Adam's original body did not start dying. Adam was literally placed into death with a body of death.
Likewise, when a body and a spirit come together, a soul is formed. However, if you remove the body, the spirit will remain, but the soul will be lost.
Again, "mortal" doesn't mean "dead." A body subject to death is still alive. And Luke 8 doesn't support your contention that demonic spirits can possess a soul.
Why would the Holy Spirit remain in a dead mortal body?
Once again you hold this term spirit as something created. The verse claims the breath of life is God and comes from God. That would be the Holy Spirit. God gave that spirit, and that spirit returns to God. So it was not created, but on loan.
What does a demon possess then? Your soul is the mind and heart. Certainly not the brain and the heart that pumps blood. The brain and heart organ are merely physical.
No. I am arguing that at death, the body and the spirit separate and as a result soul ceases to exist. What enters the grave is the body, which is subject to decay as it returns to dust. The spirit returns to God who gave it.
The concept of the "soul" refers to the life a person lives, encompassing all of their experiences, relationships, accomplishments, struggles, and everything in between from birth until death. Once a person passes away, their life comes to an end and they cease to exist. The only possibility for continued existence would be through some sort of resurrection from death.
Why do you say the spirit remains with the body removed and the body remains with the spirit removed? The only thing that God created was the dust of the physical body.
If we had that original body that was permanent and incorruptible, that body would never die. The only body that returns to dust is this second body of death, you call mortal.
Once again the soul is the eternal you. It does not matter what physical body God places that soul in. God could place that soul into a physical star, no? Then you would experience reality as a star, no? You can never cease to exist, not even in death, because you are in death in your current body and you are separated from your spirit. Because that spirit in you is the Holy Spirit, not your spirit.
The phrase "the soul of David was abandoned to the grave" indicates that all of David's activities, hopes, dreams, aspirations, plans, loves, hates, goals, and his way of life have come to an end. After he was buried, he was no longer able to serve as the King of Israel, provide for his family and people, or defend his country against their enemies. He was no longer a living soul, so his story ended there.
My argument is based on the implications of Genesis 2:7. God took dust from the ground and breathed into it and it became a living soul. The adjective indicates that Adam was active, busy, occupied with everyday life, setting goals, performing tasks and things such as these. When a body dies, the spirit, not the soul, returns to God who gave it. The soul ceases to exist.
David did not cease to exist. David was in Abraham's bosom and only tasted death. In fact he was better off in Abraham's bosom than the physical mortal body. Because he was no longer bound in sin and death. There was no longer any guilt or dread associated with sin and disobedience.
David was still separated from a physical body and his spirit. His body was dissolving in a tomb under Jerusalem, and the Holy Spirit returned to God.
Jesus told us about Abraham's bosom. People tend to dismiss God's Word as irrelevant. David said:
"Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me."
"If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there."
How can David cease to exist if he claims he can be in heaven or sheol?
My argument is that John sees souls throughout the book of Revelation as always existing with or without a physical body, because you are the soul. You don't have a soul. You are the soul that can put on your physical body, and put on your spirit over that physical body. Paul said to ensure all remain blameless: soul, body, and spirit. 1 Thessalonians 5:23
"And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ."
Can you explain how you are supposed to keep the Holy Spirit blameless? The spirit in you is not your spirit, but God's, and you still have to keep your spirit blameless from becoming demonic. Certainly God's spirit in you does not become demonic.
Paul states that our glorification is pending the return of Jesus Christ. We currently possess it as an inheritance.
Paul indicates that we shall be changed, and he subsequently describes the change in the verses that follow. He compares those who have died with those who are still alive. According to him, the dead who follow Christ will first be raised from the dead before they can experience the change. This contradicts the belief that the dead are waiting in heaven for this transformation to occur.
You contradict Matthew 27 that clearly states the OT redeemed waiting as souls in Abraham's bosom were resurrected into permanent incorruptible physical bodies and ascended with Jesus as both David and Paul states leading a processession of those held captivity into heaven. Psalms 68:18
"Thou hast ascended on high, thou hast led captivity captive: thou hast received gifts for men; yea, for the rebellious also, that the LORD God might dwell among them."
Ephesians 4:8
"Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men."
Those in Christ are consistently rising first. The soul entering that permanent incorruptible physical body is an ongoing phenomenon. 2 Corinthians 5:1
"For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens."
The Greek word for spirit naturally includes the concept of "breath" (not air) since a lack of breath usually indicates a dead body. Since breath seems to animate the body, the term spirit indicates that which animates the person, e.g love, hate, dreams, wishes, beliefs, hopes, and other things that motivate a person.
With regard to the spirits of God, Paul is indicating that the spirits of God bring light, that is, wisdom, knowledge, enlightenment, insight, and discernment.
The Holy Spirit animates. The Holy Spirit comes from God, and returns to God.
"And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters."
What else is this God breathed/spirit of life into us other than the Holy Spirit?
Air is still made up of elements/dust of the earth. The very atoms need the Holy Spirit moving within creation. The Holy Spirit is not part of creation created by God, but God Himself giving life to creation. The air and wind is just creation, but used to show us how the Holy Spirit is at work. John 3:6-8
"That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Marvel not that I said unto thee, Ye must be born again. The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit."
