John 3:6-8

⁶That that is born of the flesh, is flesh; and that that is born of the Spirit, is spirit.

⁷Wonder thou not, for I said to thee, It behooveth you to be born again.

⁸The Spirit breatheth where he will, and thou hearest his voice, but thou knowest not, from whence he cometh, nor whither he goeth; so is each man that is born of the Spirit.
