John 3:4-6

International Standard Version

⁴ Nicodemus asked him, “How can a person be born when he is old? He can’t go back into his mother’s womb a second time and be born, can he?”

⁵ Jesus answered, “Truly, I tell you^[a] emphatically, unless a person is born of water and Spirit he cannot enter the kingdom of God.^{[b] 6} What is born of the flesh is flesh, and what is born of the Spirit is spirit.
