Romans 8:5-9

For they that are after the flesh mind the things of the flesh; but they that are after the Spirit the things of the Spirit. For the mind of the flesh is death; but the mind of the Spirit is life and peace: 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.
