Romans 8:12-17

So then, brothers, we are obligated not to the flesh, to live according to the flesh. For if you live according to the flesh, you are going to die, but if by the Spirit you put to death the deeds of the body, you will live. For all those who are led by the Spirit of God, these are sons of God. For you have not received a spirit of slavery leading to fear again, but you have received the Spirit of adoption, by whom we cry out, “Abba! Father!” The Spirit himself confirms to our spirit that we are children of God, and if children, also heirs—heirs of God and fellow heirs with Christ, if indeed we suffer together with him so that we may also be glorified together with him.
