Rom. 8:12–17

12So then, brothers, we are debtors, not to the flesh, to live after the flesh.
13For if you live after the flesh, you must die; but if by the Spirit you put to death the deeds of the body, you will live.
14For as many as are led by the Spirit of God, these are children of God.
15For you didn’t receive the spirit of bondage again to fear, but you received the Spirit of adoption, by whom we cry, “Abba! Father!”
16The Spirit himself testifies with our spirit that we are children of God;
17and 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.
