And you keep ignoring that...
The contrast is between “natural” and “spiritual”!
14 The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned.
Natural person...
G5591 (Strong)
ψυχικός
psuchikos
psoo-khee-kos'
From G5590; sensitive that is, animate (in distinction on the one hand from G4152, which is the higher or renovated nature; and on the other from G5446, which is the lower or bestial nature): - natural, sensual.
the very next verse...
15 The spiritual person judges all things, but is himself to be judged by no one. - 1 Corinthians 2:14-15
Spiritual Person...
G4152 (Strong)
πνευματικός
pneumatikos
phyoo-mat-ik-os'
From G4151; non-carnal, that is, (humanly) ethereal (as opposed to gross), or (daemoniacally) a spirit (concretely), or (divinely) supernatural, regenerate, religious: - spiritual. Compare G5591.
The contrast is between natural person and spiritual person!
The contrast is between the spiritual people and the Psychikos
The psychikos cannot receive revelation from the spirit or believe the gospel
those with the spirit may receive revelation from the spirit
Those in 1Co 1:18b-21 can and did understand the gospel
The corinthians who could not be treated as spiritual also understood and believed the gospel
all these scripture show the gospel is understandable
John 20:31 (KJV 1900)
31 But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
This clearly presupposes the gospel may be understood
2 Timothy 3:15 (KJV 1900)
15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
presupposes Holy scriptures may be understood
1 Peter 1:21–25 (KJV 1900)
21 Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God. 22 Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren,
see that ye love one another with a pure heart fervently: 23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever. 24 For all flesh
is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: 25 But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
Man is regenerated through faith in the Gospel
Isaiah 55:11 (KJV 1900)
11 So shall my word be that goeth forth out of my mouth:
It shall not return unto me void,
But it shall accomplish that which I please,
And it shall prosper
in the thing whereto I sent it.
God’s word prospers in whatever it is set out to do
Psalm 19:7 (KJV 1900)
7 ………………………The testimony of the Lord
is sure, making wise the simple.
Psalm 119:130 (KJV 1900)
130 The entrance of thy words giveth light;
It giveth understanding unto the simple.
Self explanitory
Romans 10:17 (KJV 1900)
17 So then faith
cometh by hearing, and hearing by the word of God.
The word of God brings faith. It must be understood to do so
One must believe and understand the gospel to rteceive the spirit
John 7:38–39 —KJV
“He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
(But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)”
Gal. 3:14 —KJV
“That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.”
so no spirit without faith which presupposes understandability
no regeneration without faith in the gospel
1 Pet. 1:18–23 —KJV
“Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
But with the precious blood of Christ, as of a lamb without blemish and without spot:
Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God.
Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently:
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.”
the gospel not mixed with faith does not profit
Heb. 4:2 —KJV
“For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.”
so you interpretation leaves man unable to be regenerated or to receive the Spirit
as well as contradicts all the verses which show the gospel is understandable
plus a number more I could give
