The soul and spirit is the only mind, will, and emotion of man: the body has nothing of life and spirit for itself.
Without the spirit, the body is just dead flesh.
For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away.
Like grass, the flesh is mortal and nothing else: there is no spirit, nor righteousness, nor sin in grass nor in flesh of any living creature on earth, including all physical seed of man and beast.
Adam's body shaped by God from the dust was mortal, and Jesus' body shaped by the Spirit of Christ in Mary's womb was mortal flesh made of the physical seed of man: David.
Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh.
Ps 139: God creates the soul of man a living spiritual being, and places him in mortal flesh of the mother's womb.
For thou hast possessed my reins: thou hast covered me in my mother's womb.
We are souls covered with flesh in the woman's womb.
I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth.
The substance of man is the same as the angels: Spiritual beings perfectly created by the Spirit, but for man secretly in the lowest parts of earth first, and also wrapped in flesh in the womb.
Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them.
The imperfect substance of the body of flesh and bone is created by the same Spirit through seed of man: Mortal. This is why we are made a little lower than the angels, not spiritually but bodily: we are in mortal flesh rather than immortal spiritual bodies of angels.
The hope of the saints is the resurrection of our mortal bodies into spiritual immortal bodies as the angels in heaven.
How precious also are thy thoughts unto me, O God! how great is the sum of them!
Spiritual beings created by God and lightened with the light of Christ is the power to thin, intend, and imagine with the heart and mind: no other living creature earth has this power from Christ, who made them spirit only to inhabit mortal bodies.
Natural man does not believe it, and sinful man uses his power to lust for sin against God, and does so with the flesh: the flesh has nothng to say about it.
The flesh needs to breathe, hungers and thirsts, and need to work and rest for healthy and growth, but only the sinful soul and spirit of man makes the body drunken, gluttoned, and unnecessarily unhealthy and sickly.
The only difference between sinners and saints, is saints no more take unrighteous thought and vain imagination for sinning against God, and so do not fulfill the lust of the world with the flesh: Which of course takes the Spirit of Christ living within our souls with us in mortal bodies.
That is why we are indeed of His flesh and bone, because our bodies are now His mortal body on earth, and if we endure to the end, then we too will be resurrected like His own resurrected spiritual body, which He took up from the grave.
The difference being, out spiritually resurrected bodies will not have the prints of the nails of His cross as He does.
Okay.
