John Chapter 3, Verse 6
From BibleWiki
6: το γεγεννημενον εκ της σαρκος σαρξ εστιν και το γεγεννημενον εκ του πνευματος πνευμα εστιν
6: That which is born of the flesh is flesh; and that which is
born of the Spirit is spirit.
6: That which is born of the flesh is flesh: and that which is born of
the Spirit is spirit.
That which is born of the flesh. To show the necessity of this change, Jesus directs the attention of Nicodemus to the natural condition of man. By that which is born of the flesh he evidently intends man as he is by nature, in the circumstances of his natural birth. Perhaps, also, he alludes to the question asked by Nicodemus, whether a man could be born when he was old? Jesus tells him that if this could be, it would not answer any valuable purpose; he would still have the same propensities and passions. Another change was therefore indispensable.
Is flesh. Partakes of the nature of the parent. Comp. Gen 5:3. As the parents are corrupt and sinful, so will be their descendants. See Job 14:4. And as the parents are wholly corrupt by nature, so their children will be the same. The word flesh here is used as meaning corrupt, defiled, sinful. The flesh in the Scriptures is often used to denote the sinful propensities and passions of our nature, as those propensities are supposed to have their seat in the animal nature.
"The works of the flesh are manifest, which are these: adultery, fornication, uncleanness, lasciviousness," &c., Gal 5:19, Gal 5:20. See also Eph 2:3 1 Pet 3:21, 1 Pet 2:18 1Jn 2:16 Rev 8:5
Is born of the Spirit. Of the Spirit of God, or by the agency of the Holy Ghost.
Is spirit. Is spiritual, like the spirit, that is, holy, pure.
