John 3:1-5 NIV

[1] Now there was a Pharisee, a man named Nicodemus who was a member of the Jewish ruling council. [2] He came to Jesus at night and said, “Rabbi, we know that you are a teacher who has come from God. For no one could perform the signs you are doing if God were not with him.” [3] Jesus replied, “Very truly I tell you, no one can see the kingdom of God unless they are born again.” [4] “How can someone be born when they are old?” Nicodemus asked. “Surely they cannot enter a second time into their mother’s womb to be born!” [5] Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit.
