Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews.
This man came to Jesus by night and said to him,
“Rabbi, we know that you are a teacher come from God,
for no one can do these signs that you do unless God is with him.”
Jesus answered him,
“Truly, truly, 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,
“Truly, truly, I say to you,
unless one is born of water and the Spirit,
he cannot enter the kingdom of God.”
John 3:1-5
