I think that maybe the Bible should be our guide instead of personal opinion:
Psa 104:29 Thou hidest thy face, they are troubled: thou takest away their breath, they die, and return to their dust. 30 Thou sendest forth thy spirit, they are created: and thou renewest the face of the earth.
Job 14:10 But man dies and is laid low; he breathes his last and is no more. 11 As water disappears from the sea or a riverbed becomes parched and dry, 12 so man lies down and does not rise; till the heavens are no more, men will not awake or be roused from their sleep.
Psa 13:3 Consider and hear me, O LORD my God: lighten mine eyes, lest I sleep the sleep of death;
Eccl 9:5 For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. 6 Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun.
Psa 6:5 For in death there is no remembrance of thee: in the grave who shall give thee thanks?
Psa 146:3 Put not your trust in princes, nor in the son of man, in whom there is no help. 4 His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.
Ezek 18:4 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die. 20 The soul that sinneth, it shall die.
Psa 22:29 All they that be fat upon earth shall eat and worship: all they that go down to the dust shall bow before him: and none can keep alive his own soul. 18 Behold, the eye of the LORD is upon them that fear him, upon them that hope in his mercy; 19 To deliver their soul from death, and to keep them alive in famine.
Psa 56:13 For thou hast delivered my soul from death: wilt not thou deliver my feet from falling, that I may walk before God in the light of the living?
Psa 89:48 What man is he that liveth, and shall not see death? shall he deliver his soul from the hand of the grave?
