Romans 8:9-17

However, you are not [living] in the flesh [controlled by the sinful nature] but in the Spirit, if in fact the Spirit of God lives in you [directing and guiding you]. But if anyone does not have the Spirit of Christ, he does not belong to Him [and is not a child of God]. [Rom 8:14] If Christ lives in you, though your [natural] body is dead because of sin, your spirit is alive because of righteousness [which He provides]. And if the Spirit of Him who raised Jesus from the dead lives in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit, who lives in you. So then, brothers and sisters, we have an obligation, but not to our flesh [our human nature, our worldliness, our sinful capacity], to live according to the [impulses of the] flesh [our nature without the Holy Spirit]— for if you are living according to the [impulses of the] flesh, you are going to die. But if [you are living] by the [power of the Holy] Spirit you are habitually putting to death the sinful deeds of the body, you will [really] live forever. For all who are allowing themselves to be led by the Spirit of God are sons of God. For you have not received a spirit of slavery leading again to fear [of God’s judgment], but you have received the Spirit of adoption as sons [the Spirit producing sonship] by which we [joyfully] cry, “Abba! Father!” The Spirit Himself testifies and confirms together with our spirit [assuring us] that we [believers] are children of God. And if [we are His] children, [then we are His] heirs also: heirs of God and fellow heirs with Christ [sharing His spiritual blessing and inheritance], if indeed we share in His suffering so that we may also share in His glory. [John 17:24; Gal 3:29; 4:7; Eph 1:3, 11; 3:6; Heb 6:12]
