The Greek does not mean "natural."
That is a bad translation.
Accurately translated, it would read more like...
"the soulish man."
In the New Testament, "natural man" comes from the Greek phrase (psychikos anthropos).
The adjective psychikos derives from psyche (soul), meaning "soulish", earthly, or governed
by human senses and instincts without the influence of the Holy Spirit.
Hence, a man being only body and soul.
Having no human spirit.
And, that passage about the 'natural man' speaks of his inability to learn Bible doctrine.
That does not mean that the essence of God has no way to make something known that
would intrigue and draw that man to wonder what was going on.
I was given dreams that came true that were exceptional. I had no idea it was God.
But, I instinctively understood that something supernatural was going on. God was
drawing me into a realm that resided outside of my natural ways to reference reality.
I was beginning to realize that something was existing beyond what we can naturally
know.
God draws the natural man. Regeneration makes us able to comprehend Bible doctrine.
