Paul has spent a chapter answering the wretched man's cry, and now he says what the answer feels like from the inside. 15"You did not receive the spirit of slavery to fall back into fear." Instead the Spirit of adoption has come. Paul's Roman readers knew what adoption meant. It was how a private citizen could become the most powerful man in Rome, as when Julius Caesar's will adopted his great-nephew Octavian, who took an empire along with the name. Roman adoption erased the old relationship and made the adopted son heir with every legal claim of a natural child. Paul takes that picture and says something bigger happened at conversion. The old master's claim was canceled, and a new Father's claim took its place.
Then Paul gives believers the exact word Jesus used, in Aramaic, in the one place we know he prayed it aloud, Gethsemane, the night before his death: "Abba, Father, all things are possible for you" (Mark 14:36). Paul writes the Aramaic and its Greek translation side by side, as though he cannot bear to lose either. It was Jesus' cry in his most anguished hour, now placed on the lips of everyone the Spirit has adopted. 16"The Spirit himself bears witness with our spirit that we are children of God." The witness comes first, before anything we could prove, and everything else follows from it.
17"Heirs of God and fellow heirs with Christ, provided we suffer with him." Sonship and suffering travel together. The word Jesus prayed in Gethsemane before his suffering is the word his adopted brothers and sisters pray on the way through theirs. 18"Not worth comparing with the glory that is to be revealed to us," Paul says of present suffering. Paul lets the suffering stand at full weight and insists the coming glory outweighs it.
Then the lens widens further than most readers expect. Creation 22"has been groaning together in the pains of childbirth," and believers 23"groan inwardly as we wait eagerly for adoption as sons." Creation groans, and we groan. Two voices, one labor, waiting for the same day. It is the groan of something about to give birth, straining toward a delivery already guaranteed.
Hope that is seen, Paul says, is not hope. Hope reaches for what is not yet visible, and the patience it needs is the posture of someone who knows how the story ends.
And in the waiting, when the groaning grows too heavy for sentences, Paul offers one last picture. 26"We do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words." Not knowing what to pray is the moment the Spirit prays hardest, carrying what we cannot name to the Father who searches hearts. Three voices groan through this passage, creation, believers, and the Spirit himself, and each is aimed at the Father we were taught to cry out to in the first place.
Ask when your own words last ran out. That silence was already being prayed.
Prayer
Father, thank you for the Spirit of adoption, who lets us cry Abba, the word your own Son prayed in his darkest hour. When our words run out and all we can offer is a groan too deep for language, thank you that your Spirit is already praying for us according to your will. Hold us in patient hope for what we cannot yet see, until our adoption is finished in full. In Jesus' name, amen.
