Jesus referred to being born from the water world of the womb, then reinforced the statement by saying what is born of flesh is flesh. The spirit is not the flesh, so Jesus tells Nic what is born of the spirit is spirit, contrasting that to what is born of the flesh.
In that same scene, Jesus goes on to give Nicodemus a fact that is not explained anywhere in the Old Testament regarding the snake on the pole. Jesus points to the activatingpower of belief, not works, belief. Those who just looked upon the brass snake on the pole believing God's Promise regarding snake bite were delivered from the sanke poison.
Sin is poison. Believing God's Promise delivers one from the poison, thus believing GOD is the means by which Life comes to the spirit. Not by works of righteousness but by His Spirit ... that Spirit abides in the spirit of the born again. (1 John 3:9)

Has the wackadoodlisms of non-christianity twisted your mind to ignore the context?
Jesus clarified His words for you and you ignore it so you can cling to a false notion
The only biblical use of the term “born again” occurs in John 3:3-5—although, as we shall see, similar and related expressions such as “new birth” and “regeneration” occur elsewhere in Scripture (Titus 3:5; 1 Pet 1:3, 23). In John 3:3, Jesus tells Nicodemus, “Truly, truly, I say to you, unless one is born again, he cannot see the kingdom of God.” The Greek expression translated “born again” (gennathei anothen) also means “born from above.” Jesus, it seems, makes a play on words with Nicodemus, contrasting earthly life, or what theologians would later dub natural life (”what is born of flesh”), with the new life of heaven, or what they would later call supernatural life (”what is born of Spirit”).
Nicodemus’ reply: “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?” (John 3:4). Does he simply mistake Jesus to be speaking literally or is Nicodemus himself answering figuratively, meaning, “How can an old man learn new ways as if he were a child again?” We cannot say for sure, but in any case Jesus answers, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, `You must be born again.”’ (John 3:5-7).
Here Jesus equates “born again” or “born from above” with “born of water and the Spirit.”
Clearly, the context implies that born of “water and the Spirit” refers to baptism.
1 John 3:9 [9] "Committeth not sin": That is, as long as he keepeth in himself this seed of grace, and this divine generation, by which he is born of God. But then he may fall from this happy state, by the abuse of his free will, as appears from Rom. 11. 20-22; Cor. 9. 27; and 10. 12; Phil. 2. 12; Apoc. 3. 11.
Why do you persist in closing your ears and mind to Jesus' teachings?
