The natural man void of being born again with the indwelling of the Holy Spirit cannot set his mind to focus on spiritual things (1 Cor 2:14).
You seem to be interpreting Paul's words out of context, ForestGreenCook.
Paul says in ! Cor. 1:17-18 that he did not preach to the Corinthians with words of eloquent wisdom, lest conversions be accredited to Paul's clever persuasive eloquent philosophising rather than the spiritual power of the cross itself. He says that "
the word of the cross is folly to
those who are perishing (apollumenois present passive participle), but to us
who are being saved (sOzomenois, present passive participle) it is the power of God.
He says in 1:21 "...it pleased God through the folly of what we preach to start saving (sOsai, aorist active infinitive) those who are believing (pisteuontas, present active participle) ."
He goes on in i Cor. 2 to say that in first preaching to the lost Corinthians , he did not use lofty speech or wisdom, but knew nothing among these unsaved Corinthians except Christ and Him crucified... not in plausible words of wisdom, but in demonstration of the Spirit and of power, that their faith may not be based on men's wisdom but God's power. In other words, the saving message of the gospel basics, that enable sinners to put their faith in Christ as Saviour and Lord, is not aimed at the minds (psuchE) of men, but at their spirits (pneuma).
Paul goes on next to speak of teaching a wisdom to the
mature, but this is a wisdom from God that is hidden from the rulers of this age, obsessed with ruling through oppressive coercive power, could not and cannot comprehend (2:6-9)
He says that it is these things being taught to the
mature are being revealed by the Holy Spirit to the mature who have the Holy Spirit in them to teach them (2:10-13). He is not referring to the basic gospel message of the cross aimed at the uncircumcised hearts of the lost, but the deeper things of God revealed to the renewed hearts of those who have been believers long enough to mature. These "things of the Spirit" go beyond
how to be reconciled to God through Jesus ' death and resurrection. These "things of the Spirit" are knowledge and understanding of the resources at the disposal of those who have entered into the Kingdom of God." The natural or soulish man (psuchikos anthrOpos) does not grant access to (dechetai) these things of the Spirit of God that are for the mature Christians, for they are foolishness to him. 1 Cor. 2: 14) The soulish (psuchikos) person is not a Chjristian. He does not have the Holy Spirit (Jude 1:9), so those things that pertain to living life in the kingdom of God in submission to Christ are irrelevant to them. So there is no point in trying to explain these to an unsaved person. It's casting pearls before swine. The psuchikos person without the Holy Spirit (Jude 1:9) is not a Christian, because anyone who does not have the Spirit of Christ does not belong to Him. (Rom.8:9)"
Paul's the goes on to address carnal/sarkikos
Christians ("I,
brothers, could not address
YOU...") , who are presently focused on their fleshly component of their nature; and spiritual/pneumatikos Christians, who are presently focused on the spiritual component of their nature. Both believers and unbelievers have this ability to focus on either their spiritual or fleshly component of their nature. But Paul is here speaking to his siblings, Christian who focuses on their flesh is called carnal (3:1-4).
You have assumed Paul is referring in Cor. 2:14 to the basic saving gospel message as "things of the Spirit". But the context shows it is those "things of the Spirit" reserved for "mature believers". The basic gospel message is aimed at the heart, not the mind and is the sufficient power of God for salvation for those who hear it if they believe that basic message.
