Brother, what you’re asserting has no biblical foundation at all — Scripture never says the human spirit is “part of God,” never says it is incorruptible, and never says it remained unchanged in the fall; in fact, the Word says the exact opposite: man’s spirit is dead (Eph 2:1), darkened (Eph 4:18), unable (1 Cor 2:14), and hostile (Rom 8:7) until God gives a new spirit (Ezek 36:26), which would be pointless if the old one were intact.
Your claim that the spirit “returns to God” at death does not mean it is divine or uncorrupted — Ecclesiastes 12:7 simply states that life‑breath goes back to the God who gave it, not that the human spirit is a fragment of God’s essence.
And the idea that “dead men can no longer prevent the connection” is pure speculation; Jesus says the lost remain lost even after death (Luke 16:26), and “I never knew you” (Matt 7:23) means no relationship ever existed, not that death suddenly reconnects them.
The human spirit is a created, fallen, corrupted reality — not a divine spark — and regeneration is necessary precisely because the old spirit is spiritually dead and incapable of knowing God until He makes it new.
There is a distinction between the soul of man and the spirit of man. It requires wisdom to know the difference because they are often addressed using the same written word.
The spirit is Adam was breathed into him by God: a deposit from God to man. The unseen part of a man includes the spirit of the man given by God and the soul of man created in him. Man is three parts: body, soul, and spirit.
"Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ."
You wrote "Man's spirit is dead" but the passage you cited does not say that. Here is the passage:
"And you He made alive, who were dead in trespasses and sins..."
Only that the man was dead. I agree with this. And I agree that as long as man's spirit is not connected to God, man will remain dead.
You also cited this passage:
"But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned."
Of course, I agree with this too. You further added that a mind governed by the flesh is hostile to God. This is true. I believe I addressed these things earlier. The spirit of man, as long as it remains disconnected from God who gave it, has no bearin gon the life of the man.
Perhaps you believe I am advocating for universal salvation? Nope. That is not true. When the spirit of an unrighteous man returns to God who gave it, that man does not participate in that transaction. His body and soul are destroyed in Hell
"Fear only God who can destroy both soul and body in hell."
You wrote "The human spirit is a created, fallen, corrupted reality — not a divine spark — and regeneration is necessary precisely because the old spirit is spiritually dead and incapable of knowing God until He makes it new."
I believe we see something else in the creation of man. This is called being "
born of the Spirit". Which I addressed earlier: when the spirit of man connects with God, man is born of the Spirit. The new spirit God puts into man is Christ, the "
Life-giving Spirit". Man then becomes part of the Body of Christ: His flesh and His bones.
Certainly there is more I can say about this. Is there anything you want me to expound on?
One question may be "How can the Holy Spirit
convict the world of sin, righteousness, and judgement when man is hostile to God and if man has no ability, in his fallen state, to perceive the things of the Spirit?"
"And when He (the Holy Spirit)
has come, He will convict the world of sin, and of righteousness, and of judgment: of sin, because they do not believe in Me; of righteousness, because I go to My Father and you see Me no more; of judgment, because the ruler of this world is judged."
Mind you: this is
not universal salvation. Conviction is the pronunciation of whether or not one is guilty of a standard. Many men, (most) will become offended at this conviction and their hearts will be hardened against the Lord and His people.
