I appreciate how deep you're reflecting on this. However, there's a theological point to consider regarding the immortality of the soul.
In traditional Christian belief, while God alone is inherently immortal (1 Timothy 6:16), it's also understood that God has endowed human souls with immortality. This means our souls, once created, do not cease to exist.
Also, Jesus' teaching in Matthew 10:28 says, "And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell." This indicates that the soul survives physical death, affirming its immortality.
So, while we're putting on Christ’s immortality through grace by faith, it's also true that our souls, created by God, possess an inherent immortality that aligns with that same divine grace.
Man is spirit with a soul that lives in a body
1 Thess 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.
(MY NOTE: Humans are Spirit, Soul & Body)
Heb 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the "dividing asunder of soul and spirit", and of the joints and marrow, and is a discerner of the thoughts and intents of the heart..
(MY NOTE: Man can't physically see nor separate soul from spirit, however, GOD CAN)
Your soul is your thoughts & emotions that direct the actions we take. And functions only, in relation with our body. Our spirit is the eternal part of each of us. Your body, well look into a mirror.
God is Spirit: John 4:24. A spirit doesn't have flesh and blood. Luke 24:39
God who is Spirit, Breathed (Nishmat Hayyim) His life giving spirit into mans body:
Gen 2:7. And man became a living soul.
(MY NOTE: It's only a "living soul" in relation to & in conjunction with the body. When the body dies & the two are no longer one. Yet, the spirit continues to lives on.
Matt 16:26 & Mk 8:36 What would it profit a man. To gain the whole world & lose his soul.
(MY NOTE: A soul can be lost).
Ecc 12:7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
Our choices in this life will determine whether our spirit spend eternity in the presents of God (all those/BELIEVERS at the bema/judgment seat of Christ) our creator with our soul intact, will live in His presence forever. All those at the white throne judgment/that rejected Jesus as Lord). Will spend eternity separated from God their creator with their soul being lost.
