Annihilation of the soul, page-7

"The spirit of man is the candle of the Lord" (Proverbs 20:27); "There is a spirit in man" (Job 32:8); "The spirit shall return unto God who gave it" (Ecclesiastes 12:7). The soul is called in Biblical literature "ruaḥ," "nefesh," and "neshamah." The first of these terms denotes the spirit in its primitive state; the second, in its association with the body; the third, in its activity while in the body.

Because the soul is spiritual in nature, there are no “parts” to break down. Hence, the soul continues to live as a substantial, though incomplete, entity. It is in this sense that we say the soul of man does not die, while the body and the person do

1Cor 15:50 This I declare, brothers: flesh and blood cannot inherit the kingdom of God, nor does corruption* inherit incorruption.
51 Behold, I tell you a mystery. We shall not all fall asleep, but we will all be changed,
52 in an instant, in the blink of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised incorruptible, and we shall be changed.
53 For that which is corruptible must clothe itself with incorruptibility, and that which is mortal must clothe itself with immortality.
54 And when this which is corruptible clothes itself with incorruptibility and this which is mortal clothes itself with immortality, then the word that is written shall come about:
“Death is swallowed up in victory.
55Where, O death, is your victory?
Where, O death, is your sting?”
56The sting of death is sin, and the power of sin is the law.
57But thanks be to God who gives us the victory through our Lord Jesus Christ.
58Therefore, my beloved brothers, be firm, steadfast, always fully devoted to the work of the Lord, knowing that in the Lord your labor is not in vain.

John 11:25Jesus told her, “I am the resurrection and the life; whoever believes in me, even if he dies, will live,
26and everyone who lives and believes in me will never die. Do you believe this?”
Luke 20:36They can no longer die, for they are like angels; and they are the children of God because they are the ones who will rise.
38and he is not God of the dead, but of the living, for to him all are alive.
