Summary: Living by human nature cannot please God. True life is in the Spirit, evident if Christ's Spirit dwells in us. This Spirit brings life to our mortal bodies, just as it raised Christ.
Brothers and sisters:
Those who are in the flesh cannot please God. But you are not in the flesh; on the contrary, you are in the spirit, if only the Spirit of God dwells in you.
Whoever does not have the Spirit of Christ does not belong to him. But if Christ is in you, although the body is dead because of sin, the spirit is alive because of righteousness.
If the Spirit of the one who raised Jesus from the dead dwells in you, the one who raised Christ from the dead will give life to your mortal bodies also, through his Spirit dwelling in you.
