it means you reincarnate
Answer:
The word used in the Bible for "born" is "gennao," which entails the entire physical birth process from conception through gestation to parturition. God is talking about the "spiritual" birth process of His Children, from the time that He "begets" the Child with His Seed merging with our spirit, the Holy Spirit dwelling within us. A spark of the Father's Life within us.
"The Spirit itself beareth witness with our spirit, that we are the children of God..." (Rom.8:16).
Once the human spirit is "impregnated" with the Father's Seed, the Word of God, the Bread of Life, becomes the nourishment that feeds our spirit, mind and heart toward the struggle to develop and grow in the "divine nature" of our Father. Godly character, as the human father's nature is imparted to his child.
"Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust." (II Peter 1:4)
The Holy Spirit becomes the "umbilical cord" providing the nourishment of Truth, knowledge and understanding revealed to our spirit through Christ.
The struggle toward birth is the inward spiritual battles to overcome the pulls of the flesh and the world.
"...To him that overcometh will I give to eat of the Tree of Life." (Rev.2:7)
"...He that overcometh shall not be hurt of the second death." (Rev.2:11)
"...To him that overcometh will I give to eat of the hidden manna..." (Rev.2:17)
"...he that overcometh, and keepeth My works unto the end, to him will I give power over the nations..." (Rev.2:26).
"...He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the Book of Life, but I will confess his name before My Father, and before His angels." (Rev.3:5)
"...Him that overcometh will I make a pillar in the temple of My God..." (Rev.3:12).
"...To him that overcometh will I grant to sit with Me in My throne, even as I also overcame, and am set down with My Father in His throne." (Rev.3:21)
"...He that overcometh shall inherit all things; and I will be his God, and HE SHALL BE MY SON." (Rev.21:7)
Every human child conceived struggles to be born... struggling to develop properly, to take in all the proper nourishment as the mother is able to provide. And as the time draws near, the labor pains set in and the greatest struggle takes place for mother and child in great distress in the delivery.
Overcoming the flesh is the "mental" inward struggle of God's Children who, in spite of the inward delight of God's law in our heart and mind, are still flesh and blood and still subject to the law of sin in the flesh.
"We know that the law is spiritual but I am unspiritual, sold as a slave to sin. I do not understand what I do. For what I want to do I do not do, but what I hate I do. And if I do what I do not want to do, I agree that the law is good. As it is, it is no longer I myself who do it, but it is sin living in me.
"I know that nothing good lives in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. For what I do is not the good I want to do; no, the evil I do not want to do - this I keep doing.
"Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it. So I find this law at work: When I want to do good, evil is right there with me.
"For in my inner being I DELIGHT IN GOD'S LAW; but I see another law at work in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin at work within my members.
"What a wretched man I am! Who will rescue me from this body of death?
"Thanks be to God - through Jesus Christ our Lord! So then, I myself in my mind am a slave to God's law, but in the sinful nature a slave to the law of sin." (Rom.7:14-25 NIV)
There is the Christian's struggle to overcome his physical nature to be born. Feeding the inner being, his spirit, and crying out to be delivered.
"We know that the whole creation has been groaning as in the pains of childbirth right up to the present time. Not only so, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for our adoption as sons, the redemption of our bodies." (Rom.8:22-23)
So, the struggle of the birth process will continue until Jesus Christ "delivers" us.
"And so all Israel will be saved, as it is written: The Deliverer will come from Zion; He will turn godlessness away from Jacob." (Rom.11:26)
