Romans 8:9-10

9But you are not like that. You no longer obey your weak human thoughts. Instead, you obey God's Spirit as your guide. That is true if God's Spirit is really living in you. But if anyone does not have Christ's Spirit in them, that person does not belong to Christ.

10But, if Christ lives in you, you have a new life because of his Spirit. Your body will die one day because of the power of sin. But your spirit lives because Christ has made you right with God.
