“For a beastly man perceiveth not those things that be of the Spirit of God; for it is folly to him, and he may not understand, for it is examined ghostly [for it is examined, or assayed, ghostly].”
Perception is everything. The beastly man – that is the natural man – is incapable of seeing “those things that be of the Spirit of God.” Why? Because the things of God are “folly to him.” The natural man is incapable of understanding the things of God. Why? Because “the things that be of the Spirit of God” are “examined or assayed ghostly.”
Therefore, it follows that men and women in their natural state are incapable of discerning the Spirit of God.
What is needed?
The natural man requires illumination. The Holy Spirit must reveal Himself to the natural man so that he or she is able to see and understand the things of God. Why? Because the things which be of the Spirit of God are discerned and understood and appreciated by the very Spirit of God, i.e. through God’s power.
We become the children of God not by the “will of flesh, neither of the will of man, but be born of God.” (John 1: 13, WYC)
