Romans 15: One welcome, a wide mission, and unfinished travel plans

Romans 15 completes the food-and-days argument by redefining strength as the ability to carry another person's weakness rather than display personal liberty. Christ's refusal to please himself supplies the pattern, and Scripture supplies patience, comfort, and hope until one divided community can glorify God "with one mind and one mouth." Paul then connects that welcome to the letter's larger Jew-Gentile argument. Christ confirms the promises to the fathers, while Gentiles glorify God for mercy, and a chain of quotations makes both belong inside the same scriptural horizon. The chapter then becomes increasingly personal. Paul explains his Gentile mission, his desire to preach where Christ has not been named, his plan to reach Spain through Rome, and the collection he must first deliver to Jerusalem. The confident itinerary ends in requested prayer for danger and uncertain reception, showing a theology carried through roads, money, communities, and circumstances Paul cannot control.
