Why does Paul use such intimate and repeated language like 'Abba! Father!'? It's more than just a name; it's a powerful declaration of our new identity.
The 'Spirit of adoption' is the Holy Spirit Himself, who testifies within us that we are God's children. This isn't just being tolerated or accepted; it's being placed in the position of a son, with all the rights and intimacy that entails. The cry, 'Abba! Father!' captures this profound relationship. 'Abba' is an Aramaic term, a deeply personal and intimate word for 'Father,' similar to how a child might say 'Daddy.' Paul adds the Greek 'Father' to emphasize that this intimate relationship is now available to all – Jew and Gentile alike. This cry isn't just an emotional outburst; it's a confident plea, a declaration of belonging, and a recognition of God's protective care.
