Romans 8:11-16

But if the Spirit of him that raised up Jesus from the dead dwelleth in you, he that raised up Christ Jesus from the dead shall give life also to your mortal bodies through his Spirit that dwelleth in you. So then, brethren, we are debtors, not to the flesh, to live after the flesh: for if ye live after the flesh, ye must die; but if by the Spirit ye put to death the deeds of the body, ye shall live. For as many as are led by the Spirit of God, these are sons of God. For ye received not the spirit of bondage again unto fear; but ye received the spirit of adoption, whereby we cry, Abba, Father. The Spirit himself beareth witness with our spirit, that we are children of God
