Romans 8:12-17

12Therefore, brothers and sisters, we have an obligation—but it is not to the flesh, to live according to it.

13For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live. 14For those who are led by the Spirit of God are the children of God. 15The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. The Greek word for adoption to sonship is a term referring to the full legal standing of an adopted male heir in Roman culture; also in verse 23. And by him we cry, “ Abba, Aramaic for father Father.” 16The Spirit himself testifies with our spirit that we are God’s children.

17Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
