Jesus answered, Truly, truly, I say to you, Unless one is born of water and the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, You must be born anew. The wind blows where it wills, and you hear the sound of it, but you do not know where it comes from and where it goes; so is everyone who is born of the Spirit. [ John 3:5-8 ]
