Thats what it means, whats the difference between me writing the definition out freehand for you or directing you to the place.
Try comparing between carnal and spiritual things here
There are carnal things and spiritual things, one pertains to the flesh/physical/natural and the other belongs to the Spirit.
The natural man does not receive the things of the Spirit
Wherever strife is there is the natural man/ carnal man
1 Cr 3:1 And I, brethren, could not speak unto you as unto spiritual, but as unto carnal,
even as unto babes in Christ.
1 Cr 3: 1-2 I have fed you with milk, and not with meat: for hitherto ye were not able
to bear it, neither yet now are ye able.
1 Cr 3: 3 For ye are yet carnal: for whereas
there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
So just as I might regard the nature of death pertaining to the flesh (on the one account) as it relates to what is physical.carnal and under the power of the flesh and its mindedness relating to death, hatred divisions, strifes etc, those things belong to carnality
On the other hand that which is spiritual has passed from death unto life and peace (even though the carnal counterpart will seek for war) These are teachable and more ready to receive what the Spirit teaches them, whereas the other cannot receive those things.
Even in respects to the Spirit's teaching, he changes the way we are able to receive things and does so through comparing even as Paul speaks of it. One can discern far more then the other because one is by its own strength (the flesh) which is weak and the other is by the Spirit of God which exceeds our own strength.
Thats just a brief summary
