John 3:1-5 New Revised Standard Version (NRSV)
Nicodemus Visits Jesus
3 Now there was a Pharisee named Nicodemus, a leader of the Jews. 2 He came to Jesus[a] by night and said to him, “Rabbi, we know that you are a teacher who has come from God; for no one can do these signs that you do apart from the presence of God.” 3 Jesus answered him, “Very truly, I tell you, no one can see the kingdom of God without being born from above.”[b] 4 Nicodemus said to him, “How can anyone be born after having grown old? Can one enter a second time into the mother’s womb and be born?” 5 Jesus answered, “Very truly, I tell you, no one can enter the kingdom of God without being born of water and Spirit.
