Are you intentionally avoiding some of the scriptural references and objective questions that surround your claims about the soul and body? If you believe that man should live by every word of God, then you need to consider every word that is spoken. You can't dismiss anyone by telling them that they do not understand the present topic of discussion.
Who are you addressing? If it's to me, I posted my "you do not understand death" post from a tablet. I apologize for the brevity.
Yes. We need to live by every word of God. We all do. Here are some scripture regarding death:
Deut 31:16) And the LORD said unto Moses, Behold, thou shalt sleep with thy fathers…
Job 7:21) …For now I shall lie in the earth; you will seek me, but I shall not be.
Psalm 6:5) For in death there is no remembrance of you; in Sheol who will give you praise?
Psalm 30:9) What profit is there in my death, if I go down to the pit? Will the dust praise you? Will it tell of your faithfulness?
Psalm 49:12) Man in his pomp will not remain; he is like the beasts that perish.
Psalm 115:17) The dead do not praise the LORD, nor do any who go down into silence.
Ecc 9:
4) But he who is joined with all the living has hope, for a living dog is better than a dead lion.
5) For the living know that they will die, but the dead know nothing, and they have no more reward, for the memory of them is forgotten.
6) Their love and their hate and their envy have already perished, and forever they have no more share in all that is done under the sun.
10) Whatever your hand finds to do, do it with your might, for there is no work or thought or knowledge or wisdom in Sheol, to which you are going.
John 3:13) No one has ascended into heaven except he who descended from heaven, the Son of Man.
Acts 2:
29) Brothers, I may say to you with confidence about the patriarch David that he both died and was buried, and his tomb is with us to this day.
30) Being therefore a prophet…
31) he foresaw and spoke about the resurrection of the Christ, that he was not abandoned to Hades, nor did his flesh see corruption.
32) This Jesus God raised up, and of that we all are witnesses.
34) For David did not ascend into the heavens…
Those verses plainly teach that dead people are dead. Dead people will be raised in the future at one of the upcoming resurrections.
Question: There can be no doubt that man is made of spirit, soul and body according to (1Thes 5:23). If at death the soul and body go into the grave as dead until the resurrection, what happens to the human spirit that is in man as the candle of the Lord (Prov 20:27)? Does the human spirit represent the person that has died and wait in heaven to be reunited with the soul and body at the resurrection? Remember what Stephen said being stoned to death in (Act 7:59), 'Lord Jesus receive my spirit'.
Both the words "soul" and "spirit" have many meanings in the bible, as they do in English. Soul can refer to that which gives life to the body (nephesh in Genesis), it can refer to people as a whole (psuche in Acts 27:37). The same is true for the word "spirit".
Stephen will be resurrected from death when Christ returns to gather the church.
