natural and spirit do not compute.
1 Corinthians 2:14 But the natural, nonspiritual man does not accept or welcome or admit into his heart the gifts and teachings and revelations of the Spirit of God, for they are folly (meaningless nonsense) to him; and he is incapable of knowing them [of progressively recognizing, understanding, and becoming better acquainted with them] because they are spiritually discerned and estimated and appreciated.
I see man a spirit, soul and flesh. Man spirit is what we are for we were all created in God's image and likeness and God is a spirit so that that image and likeness is a spirit part of man our essence of who we rally are.
When Adam died because of sin he did not die physically for he lived to be 930 years old but his spirit died to the realm of God. So Adam became a became a soul man, a dust man a non-spiritual man.
So to understand spiritually dead we need to see God uses physical/natural realities as examples for that what is spiritual or a spiritual language. Seriously is the lamb of God a bay sheep that eats grass. Same with the realm of spiritual death. So when Ephesians speaks of dead in trustpasses and sins it is speaking of the spirit being dead to the realm of God.
That is why carnal man cannot choose salvation for he sees all things from God as foolishness because he is dead from the realm of God. It takes God's grace, his drawing his quickening to make us alive spiritually so we can begin our spiritual walk.
I see some things differently than you.
Firstly;
Natural man = man of dust of the earth.
Natural man = Carnal, Mortal, subject to death, ie WILL die.
The form, ie the body
The covering of the form, ie the flesh
All that is within the natural body,
Ie
Blood = life of man
Heart = keeps life of blood functioning
Natural spirit = True thoughts IN HEART
Brain= True & false thoughts IN MIND
systems = nerves, bones, organs, muscles, etc.
Natural man ~ Becomes an ALIVE & LIVING individual
When God gives a man A LIVING SOUL, via His BREATH.
Natural man is corrupt ~
Born IN SIN.
.....does not know or Believe in God
Can do nothing of his own, works, ideas, power, etc. to please God.
Every day the man is NOT WITH God, his internal living soul, is being corrupted, being in the mans corrupt body of sin.
Jesus' WAY, to resolve the corrupt man's sin..
Is to learn about Him
...called being enlightened
The man being enlightened, is given ..measures of faith
If the man continues learning ABOUT God
....and believing what he learns
....his faith is increased.
If the man stops believing, stops following and learning
...the man falls away from faith
...he stops receiving enlightenment
...he stops receiving faith from God.
If the man continues learing and believing...
....AND his TRUE BELIEF is from his
...natural spirits thoughts in his heart.
......And the man CONFESSES his true belief
......from his heart to God...
THAT ^ is a declaration, a VOW to God,
Of the man Giving His living body as
A sacrifice TO GOD.
THEN GOD CONVERTS the man.
The mans ....
Natural body of sin is forgive, for disbelief
Spiritual soul is forgiven its sin of corruption
Natural body is spiritually crucified with Christ
Natural body is washed in Jesus' blood
Natural body is sanctified, by Jesus' blood
Natural body is justified, to be redeemed
Natural body is Kept with Christ.
Spiritual soul is RESTORED
Natural heart is CIRCUMCISED, ie new heart
Natural spirit is BORN again, from Gods Seed
Gods Spirit dwells in new heart, with mans
....new spirit.
God Spirit, Spirit of Truth, fellowships with,
....teaches mans new spirit, Gods Truths.
Natural body is dead to sin, sins no more.
Natural man is called a NEW MAN.
Natural man now LIVES IN CHRIST.
Natural man now is called, a son of God.
Natural man now is Forever WITH the Lord.
Natural man is now prepared to Serve God.
Natural man is now prepared to be redeemed, at any day, the Lord descends from Heaven, and calls up the man to Him in the clouds, to have his body glorified.
That man can continue learing from the Jews, whom God Himself chose their ancestors, the Hebrews to be the Teachers to mankind.
The Jews Jesus chose, as well as Jesus' teaching, and written for the benefit of the world, TO LEARN, behaviors, works and ways that are ACCEPTABLE ways for a man to SERVE God, that GLORIFIES HIS NAME.
And men WHO accomplish Serving the Lord that DOES Glorify HIS NAME....He himself shall reward the man.
So, I disagree with you, about a mans spirit.
A mans natural spirit is his TRUTH in his heart. It is God who requires, the mans Truth in his heart, as a confession of Belief in God.
It is the natural spirit of man (his truth), that was born and foster from a man corruptible seed.
It is God INCORRUPTABLE SEED, that REBIRTHS the mans natural spirit, to a spiritual spirit, with a NEW TRUTH, ie; Gods Truth.
Secondly;
Made in Gods Likeness.
Male and Female God made and called Adam.
Adam was made in Gods Likeness and image.
Is the rest of mankind made in Gods likeness?
No.
Gen 5:1 ~ 2
God likeness is Good. Adam was made Good.
Adam fell, to what we later call sin.
Adam disobeyed the Truth, ie God.
Adams children were made in Adam's likeness and image, and thereafter the same for all men and no man is good.
Then if and when a man becomes restored, reconciled, converted, man again becomes good. Matt 12:35
Agree God draws men to Him.
God also calls MANY, but chooses few.
God Bless,
