15 For ye have not received the spirit of bondage to be in fear [again], but ye have received the Spirit of adoption [of sons], whereby we cry, Abba, Father.16 For the same Spirit bears witness unto our spirit that we are sons of God,17 and if sons, also heirs certainly of God and joint-heirs with Christ, if so be that we suffer with [him] that we may be also glorified together [with him].
