Romans 8:9-16

8:9 You, however, are not in the flesh but in the Spirit, if indeed the Spirit of God lives in you. Now if anyone does not have the Spirit of Christ, this person does not belong to him. 8:10 But if Christ is in you, your body is dead because of sin, but the Spirit is your life because of righteousness. 8:11 Moreover if the Spirit of the one who raised Jesus from the dead lives in you, the one who raised Christ from the dead will also make your mortal bodies alive through his Spirit who lives in you.

8:12 So then, brothers and sisters, we are under obligation, not to the flesh, to live according to the flesh 8:13 (for if you live according to the flesh, you will die), but if by the Spirit you put to death the deeds of the body you will live. 8:14 For all who are led by the Spirit of God are the sons of God. 8:15 For you did not receive the spirit of slavery leading again to fear, but you received the Spirit of adoption, by whom we cry, “Abba, Father.” 8:16 The Spirit himself bears witness to our spirit that we are God’s children.

Romans 8:26

8:26 In the same way, the Spirit helps us in our weakness, for we do not know how we should pray, but the Spirit himself intercedes for us with inexpressible groanings.
