This is somewhat tiresome but here is the reply, if not for you but then others.
1Co 2:6 We speak wisdom, however, among them that are fullgrown: (or mature), yet a wisdom not of this world, nor of the rulers of this world, who are coming to nought: (This portion of Scripture, is for the believers mature enough, spiritually speaking, to receive it. Mat. 5:48)
1Cor 2:7-8 but we speak God's wisdom in a mystery, even the wisdom that hath been hidden, which God foreordained before the worlds unto our glory: which none of the rulers of this world hath known: for had they known it, they would not have crucified the Lord of glory: (In God's foreordination, He planned every aspect of redemption before anything was created. In the immediate context, whom Christ was. It was not discernible by the rulers of this world,)
1Cor 2:9-10 but as it is written, Things which eye saw not, and ear heard not, And which entered not into the heart of man, Whatsoever things God prepared for them that love him. But unto us God revealed them through the Spirit: for the Spirit searcheth all things, yea, the deep things of God. (These things could not be obtained through natural means, v.9, These things were prepared by God for the ones that love Him. An obvious and particular group.)
1Cor 2:11-16 For who among men are knowing the things of a man, save the spirit of the man, which is in him? even so the things of God none are knowing, except by the Spirit of God. But we received, not the spirit of the world, but the spirit which is from God; that we might know the things that were freely given to us from God. Which things also we speak, not in words which man's wisdom is teaching, but that which the Spirit teaching; combining spiritual things with spiritual words. Now the natural man is not receiving the things of the Spirit of God: for they are foolishness unto him; and he cannot know them, because they are spiritually discerned. But he that is spiritual is discerning all things, and he himself is discerned by no man. For who hath known the mind of the Lord, that he should instruct him? But we have the mind of Christ.
Note here Paul's inclusion among the matters he is discussing: The pronoun "WE" used six times. The pronoun "US" twice.
In Chapter 3, Paul makes a clear break as to whom he is now talking too. He moves from himself and mature believers, to the babes in Christ.
1Cor 3:1 And I, brethren, could not speak unto you as ones who are spiritual, (The ones above, in Ch.2) but as ones who are carnal, as unto babes in Christ. (This is a clear break. Note: Paul uses no inclusive pronouns as he makes this division, between mature and immature.)
Now the question is: Will you now except the obvious teaching here? I make no claims, just except what the text clearly says.
1¶And I, brethren, could not speak unto you as unto spiritual,( Mature , the same ones in chapter 2 verse 6 but as unto carnal,
even as unto babes in Christ.
2I have fed you with milk, and not with meat: for hitherto ye were NOT ABLE !!
to bear it, neither yet now are YE ABLE !!!
3For ye are yet carnal: for whereas
there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
4For while one saith, I am of Paul; and another, I
am of Apollos; are ye not carnal?
its the same point in Hebrews 5
11Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
12¶For when for the time ye ought to be teachers, ye have need that one teach you again which
be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
13For every one that useth milk
is unskilful in the word of righteousness: for he is a babe.
14But strong meat belongeth to them that are of full age,
even those who by reason of use have their senses exercised to discern both good and evil.
The issue is on the trigger word ' Natural ' . But no where is ' Natural ' used towards a lost sinner else where . Natural is not negative.
rom 1 .26
26¶For this cause God gave them up unto vile affections: for even their women did change THE NATURAL use into that which is against NATURE :
27And likewise also the men, leaving the natural use of the woman,
31Without understanding, covenantbreakers, without ((natural ))affection, implacable, unmerciful:
now check the greek for ' NATURAL ' and CARNAL they both basically mean the same ( fleshy ) Which is Paul is addressing.
