Jesus replied to Nicodemus, "I can guarantee this truth: No one can see the kingdom of God without being born from above."
Nicodemus asked him, "How can anyone be born when he's an old man? He can't go back inside his mother a second time to be born, can he?"
Jesus answered Nicodemus, "I can guarantee this truth: No one can enter the kingdom of God without being born of water and the Spirit.
Flesh and blood give birth to flesh and blood, but the Spirit gives birth to things that are spiritual.
