Romans 8:7-14

because the mind of the flesh is enmity against God; for it is not subject to the law of God, neither indeed can it be: and they that are in the flesh cannot please God. But ye are not in the flesh but in the Spirit, if so be that the Spirit of God dwelleth in you. But if any man hath not the Spirit of Christ, he is none of his. And if Christ is in you, the body is dead because of sin; but the spirit is life because of righteousness. 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.
