What is a spirit?
(human spirit)
Ecc. 8:8
[There is] no man that hath power over the spirit to retain the spirit; neither [hath he] power in the day of death: and [there is] no discharge in [that] war; neither shall wickedness deliver those that are given to it.
The word spirit/Ruwach in Hebrew means wind or breath. In the scripture above, spirit means “breath”.
In Job 27:3 The human spirit is called as being breathed into man by God and returning to Him. All the while my breath [is] in me, and the spirit of God [is] in my nostrils;
In Gen. 2:7 it says that, And the Lord God formed man [of] the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Ecc. 12:7 says, Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
Job 32:8 says, But there is a spirit in man: and the inspiration of the Almighty giveth them understanding.
That word spirit used in that verse is the same word in Hebrew which is Ruwach which means breath.
So what we can gather from these scriptures are that God breathed into us life. That life is our spirits.
This “breath of life” is the spirit of life, which became man's spirit. Without the spirit, the body is dead.
James 2:26, For as the body without the spirit is dead, so faith without works is dead also.
When the spirit of life entered into man's physical body by God, “man became a living being”.
So in essence we are our spirits. You could say we are a spirit and we live in a natural body. We don't have a spirit we are a spirit. Without it we are dead.
