Romans 8:15-18

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.

Present Suffering and Future Glory 18I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.
