1Co 2:13 KJV Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
“Walk in the Spirit,” Paul says in Romans 8. Because those who walk in the Spirit know the things given freely to them.
The bible says that these things, are only explained by a Spiritual wisdom. A spiritual Understanding of operations.
Yes, the mystery of salvation to the gentiles is one of the free gifts.
But There are other Spiritual things we have that even the Natural man cannot Get, Because he has not the Spirit Nor does he understand the wisdom of the Spirit.
Spiritual Man – He that Has the Spirit of God in him(born again) And walks according to the Spirit
Carnal Man – Born again but walks according to the flesh. Gratifies the desires of the flesh.
Natural Man – Does not have the Spirit of God. He is not born again, and spiritual things to him are foolishness. He is fully religious.
