Romans 8
15 Ref For you didn't receive the spirit of bondage again to fear, but you received the Spirit of adoption, by whom we cry, "Abba{Abba is a Chaldee word for father or daddy, often used affectionately and respectfully in prayer to our Father in heaven.}! Father!"
16 Ref The Spirit himself testifies with our spirit that we are children of God;
17 Ref and if children, then heirs; heirs of God, and joint-heirs with Christ; if indeed we suffer with him, that we may also be glorified with him.
