People that live following their sinful selves think only about things that their sinful selves want. But those people that live following the Spirit F62 are thinking about the things that the Spirit wants them to do.
If a person's thinking is controlled by his sinful self, then there is spiritual death. But if a person's thinking is controlled by the Spirit, then there is life and peace.
Why is this true? Because if a person's thinking is controlled by his sinful self, then that person is against God. That person refuses to obey God's law. And really that person is not able to obey God's law.
But you are not ruled by your sinful selves. You are ruled by the Spirit, F63 if that Spirit of God really lives in you. But if any person does not have the Spirit of Christ, then that person does not belong to Christ.
God raised Jesus from death. And if God's Spirit is living in you, then he will also give life to your bodies that die. God is the One who raised Christ from death. And he will give life to your bodies through his Spirit that lives in you.
If you use your lives to do the wrong things your sinful selves want, then you will die spiritually. But if you use the Spirit's F64 help to stop doing the wrong things you do with your body, then you will have {true} life.
