Introduction
Paul does not merely ask that the gospel be preached. He asks Christians to pray that it will run and be glorified. The picture is of the word moving without obstruction and receiving the honor it deserves when people recognize its truth, submit to its authority, and display its power in changed lives.
Paul points to Thessalonica as evidence: “just as it is with you.” The word had already run into that city. It was glorified there because people received it, obeyed it, lived by it, modeled it, and carried it to others.
Marvin Vincent takes “run” as having swift progress through the world and “be glorified” as being acknowledged in its true power and glory. The athletic image also appears in Psalm 147:15: God’s word “runs very swiftly.” Paul asks for prayer, not applause for the messenger. Compare Ephesians 6:18–20, Colossians 4:2–4, and Acts 13:48–49.
Teaching question: What would it look like for the word to be glorified in a person rather than merely known by that person?
