Paul has now set the stage by recounting the Colossian church's testimony. He has warned them against losing hope in the one true gospel. He now delineates his role and theirs in what is to come next:
Now I rejoice in my sufferings for you, and fill up in my flesh whatever is lacking of the sufferings of Christ for the sake of his body, which is the church. I have become a minister of the church according to the stewardship of God given to me with you in view, to make the word of God fully known. This is the mystery which has been concealed for ages and generations, but has now been manifested to his saints. To them God chose to make known the glorious wealth of this mystery among the Gentiles - it is Christ in you, the hope of glory. It is he whom we preach, as we instruct everyone and teach everyone in all wisdom, so as to present everyone perfect in Christ. This indeed is the end for which I labor, contending according to his power which operates mightily within me.
It shouldn't be surprising that Paul identifies his own suffering with the messiah's. As F.F. Bruce points out in his commentary, Paul's experience on the Damascus road taught him that the messiah himself identified the sufferings of his people with his own suffering. Though Paul (then Saul) persecuted Christians, Jesus ask the question this way: "Saul, Saul, why do you persecute
me?" As Bruce puts it, "Christ suffered in his people." Bruce also notes that Paul and Barnabas allude to the Isaianic servant passages when they turn their mission toward the Gentiles at Pisidian Antioch. For Paul, "... the Servant's mission of enlightenment to the nations is to be carried on by the representatives of Christ."
The idea of filling up what is lacking is an eschatological concept. Bruce says that a "quota of affliction" before the end could come is a rabbinical idea. It is certainly a New Testament theme (here in Paul and I think in Revelation as well). It is also an early church concept. In
The Shepherd of Hermas, a metaphor of a tower being built plays the same illustrative role. When the last stone is placed in the tower, the end comes.
Verse 27 is grammatically odd. Perhaps Paul's meaning was something akin to the following paraphrase: "God chose you to be his agents to make known the glorious wealth of the messiah among the rest of the Gentiles. The hope of their glory is the messiah in you." To the saints, God had given the task of making him known by putting Christ on full display. Paul is calling on the Colossians to join him in this project of revealing the mystery to the broader Gentile world. Certainly, the Jewish messiah being found in and revealed by a bunch of Gentiles from Asia Minor is a striking witness to the watching world that the salvation promised by the god of Israel is now opened to everyone.
Indeed, Paul's goal is nothing short of salvation for the entire world. The threefold "...every man... every man... every man" in 1:28 drives the point home. The mystery that had been hidden from the Gentiles (obscurely in the law and prophets) is now on display. In Christ, revelation takes the place of apocalypse and the church must now bring to completion the suffering which Christ had begun. In order to achieve the full eschatological measure, the Colossians will need to hold firm to reveal the Jewish messiah in them (oddly enough) to their fellow Gentiles. The cross was not the end of pain, suffering, and death; it was only the beginning.
