Romans 8:12-17

Therefore, brothers, we are debtors not to the flesh, to live according to the flesh. For if you live according to the flesh, you will die, but if through the Spirit you put to death the deeds of the body, you will live. For as many as are led by the Spirit of God, these are the sons of God. For you have not received the spirit of slavery again to fear. But you have received the Spirit of adoption, by whom we cry, “Abba, Father.” The Spirit Himself bears witness with our spirits that we are the children of God, and if children, then heirs: heirs of God and joint-heirs with Christ, if indeed we suffer with Him, that we may also be glorified with Him.
