Jesus, answering Nicodemus’ question on how to be born again, said in John 3:6:
That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
At new birth, you are not born again a spiritual being; you are born again a spirit being. New birth makes you a spirit being in human flesh.
Adam was a supernatural personality in the garden. He operated in the class of God. Adam single-handedly named all the animals in the garden, all the fowls in the air, and all the fishes in the waters. God brought everything He created before Adam to name, and whatever name Adam
called them, that was the name by which they were called.
He was in the class of God, so he thought like Him. Adam was a supernatural being.
What made him supernatural was the spirit that was alive in him. But at the fall, his spirit-man died, and Adam was reduced to a natural being.
However, when Jesus came, what died in Adam was restored back to man through salvation. So, every redeemed child of God carries in his body today whatever virtues Adam carried in the garden before the fall.
That which is born of the flesh is flesh, and that which is born of the Spirit is spirit, not spiritual.
Jesus again tells us in John 4:24 that God is a Spirit.
