Jesus said it in John 3:5-6..."Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.You have never, not once provided a scripture that's says our flesh is born again.
That our flesh is born of the Spirit.
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit."
The new man is born of the Spirit.
The old man was destroyed..."Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin." (Rom 6:6)
The body of sins has been "put off"..."In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:" (Col 2:11)
Read above.Where is the scripture that says our flesh, our physical body is born again?
I will add this..."Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
10 In this the children of God are manifest, and the children of the devil: " (1 Joh 3:9-10)
The fruit determines the Father.
