Romans 8:12 - 8:17
12 So then, brothers, we are under obligation, not to the flesh, to live according to the flesh— 13 for if you are living according to the flesh, you must die, but if by the Spirit you are putting to death the practices of the body, you will live. 14 For as many as are being led by the Spirit of God, these are sons of God. 15 For you have not received a spirit of slavery leading to fear again, but you have received the Spirit of adoption as sons by whom we cry out, “Abba! Father!” 16 The Spirit Himself testifies with our spirit that we are children of God, 17 and if children, also heirs, heirs of God and fellow heirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him.
