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.
