Rom.8.9

But if God himself has taken up residence in your life, you can hardly be thinking more of yourself than of him. Anyone, of course, who has not welcomed this invisible but clearly present God, the Spirit of Christ, won't know what we're talking about.

Rom.8.9

You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ.

Rom.8.9

But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His.

Rom.8.9

But you are not controlled by your sinful nature. You are controlled by the Spirit if you have the Spirit of God living in you. (And remember that those who do not have the Spirit of Christ living in them are not Christians at all.)
