Romans 1:14-15 NASB
“(14)I am under obligation both to the Greeks and to the barbarians, both to the wise and to the foolish. (15)So, for my part, I am eager to preach the gospel to you also who are in Rome.”
The Greeks viewed everyone else on the outside to be a “barbarian”, and they also viewed themselves to be wise and most everyone else foolish, even the Jews. This reference Paul is making in his obligation is for all the work he has previously done for Jews and Gentiles, but also a reference to the barbarians in the western lands of Rome that had not yet been conquered. Even though Paul has already spent years preaching the Gospel, being shipwrecked, beaten and chased out of towns, he still feels obligated to spread the gospel far and wide. His zeal and obedience to God are supernatural. No man in the natural state of mind and heart would continue to strive the way he does and be so passionate unless he was empowered by the Holy Spirit. His eagerness to preach in Rome isn’t just necessarily for the church, but for the unsaved as well. Rome is so diverse, there would be Gentiles, Christians, and Jewish Christians. A melting pot of people from all over the continent. The phrase, “all roads lead to Rome” isn’t just a catch phrase. Rome, in it’s pinnacle of power and influence, gathered people from all over the continent by reason of travel, business or slavery. What a place to go to and preach the gospel! Many of the converts there would take the faith of Jesus Christ back to their homeland and others would be saved as well. Paul is both passionate for the gospel and strategic about it.
