15 For you have not received the spirit of bondage, again, to fear; but you have received the spirit of adoption, by which we cry, Abba, Father.16 Also this spirit bears witness, together with our spirit, that we are children of God.17 And if children, then heirs; heirs, indeed, of God, and joint heirs with Christ; if, indeed, we suffer with him, that with him also we may be glorified.
