John 3:2-4

Amplified Bible

² who came to Jesus at night and said to Him, “Rabbi (Teacher), we know [without any doubt] that You have come from God as a teacher; for no one can do these signs [these wonders, these attesting miracles] that You do unless God is with him.” ³ Jesus answered him, “I assure you and most solemnly say to you, unless a person is born again [reborn from above—spiritually transformed, renewed, sanctified], he cannot [ever] see and experience the kingdom of God.”

⁴ Nicodemus said to Him, “How can a man be born when he is old? He cannot enter his mother’s womb a second time and be born, can he?”
