Romans 8:11-16

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.
