John 3:5-8
5 Jesus answered, “Truly, truly, I say to you, unless one is born of awater and the Spirit he cannot enter into bthe kingdom of God. 6 aThat which has been born of the flesh is flesh, and that which has been born of the Spirit is spirit. 7 Do not marvel that I said to you, ‘You must be born again.’ 8 aThe wind blows where it wishes and you hear its sound, but do not know where it comes from and where it is going; so is everyone who has been born of the Spirit.”
