Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?”Jesus answered, “Most assuredly, 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.’The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.”
Nicodemus answered and said to Him, “How can these things be?”Jesus answered and said to him, “Are you the teacher of Israel, and do not know these things?Most assuredly, I say to you, We speak what We know and testify what We have seen, and you do not receive Our witness.If I have told you earthly things and you do not believe, how will you believe if I tell you heavenly things?No one has ascended to heaven but He who came down from heaven, that is, the Son of Man who is in heaven.And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up,that whoever believes in Him should not perish but have eternal life.For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.“He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”

For we do not commend ourselves again to you, but give you opportunity to boast on our behalf, that you may have an answer for those who boast in appearance and not in heart.For if we are beside ourselves, it is for God; or if we are of sound mind, it is for you.For the love of Christ compels us, because we judge thus: that if One died for all, then all died;and He died for all, that those who live should live no longer for themselves, but for Him who died for them and rose again.Therefore, from now on, we regard no one according to the flesh. Even though we have known Christ according to the flesh, yet now we know Him thus no longer.Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation,that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation.Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God.For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. - 2 Corinthians 5:12-21 http://www.biblegateway.com/passage/?search=2Corinthians5:12-21&version=NKJV
See with what large letters I have written to you with my own hand!As many as desire to make a good showing in the flesh, these would compel you to be circumcised, only that they may not suffer persecution for the cross of Christ.For not even those who are circumcised keep the law, but they desire to have you circumcised that they may boast in your flesh.But God forbid that I should boast except in the cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world.For in Christ Jesus neither circumcision nor uncircumcision avails anything, but a new creation. - Galatians 6:11-15 http://www.biblegateway.com/passage/?search=Galatians6:11-15&version=NKJV
I think the problem here is that the phrase "born-again" has been appropriated by Christianity to mean "made into a new creature."
