Romans 8:8-10

and those who are in the flesh [living a life that caters to sinful appetites and impulses] cannot please God. However, you are not [living] in the flesh [controlled by the sinful nature] but in the Spirit, if in fact the Spirit of God lives in you [directing and guiding you]. But if anyone does not have the Spirit of Christ, he does not belong to Him [and is not a child of God]. [Rom 8:14] If Christ lives in you, though your [natural] body is dead because of sin, your spirit is alive because of righteousness [which He provides].
