John 3:3-5

Jesus answered and said to him, Verily, verily, I say unto thee, Except any one be born anew he cannot see the kingdom of God. Nicodemus says to him, How can a man be born being old? can he enter a second time into the womb of his mother and be born? Jesus answered, Verily, verily, I say unto thee, Except any one be born of water and of Spirit, he cannot enter into the kingdom of God.
