What is Spirit?
the common Greek understanding of an enduring (eternal) spirit in man defies biblical narative
While the Spirit of God is enduring only His is eternal.
When we make a comparison of every verse using "spirit" from Genesis to Ezekiel, the phrase "state of awareness" is interchangable with "spirit" every time.
Whether it is the Lords Spirit (His omnipresent awareness), a living conscious man, angel, spacial understanding, sense, emotion, skill or even mental health - each is a "state of awareness".
Sometimes spirit and soul are synonymous, but not always. The soul is the breath (presence of life) - for example: a man expresses what is going on in his spirit (conscious awareness) with his soul (breath). So in this way a man may still have a soul (be alive) while having no spirit in him, being unconscious or unable - close to death.
Scripturally, a mans spirit can not exist without his soul (breath) being present. The breath (life on loan from God) is at the heart and soul of man, while his spirit is of the mind with it he consciously perceives and makes determined choices. Without spirit a group of men have no collective will or drive (no ability to choose or act). Without spirit an individual man has either lost his sense of fortitude or is faint and near death (also no ability to choose or act).

But it is the spirit in man, the breath of the Almighty, that makes him understand.
