John 3:3-5

3Jesus 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!”

5Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit.
