Obligated to the Foolish

Paul longed to visit the believers in Rome so that he might impart some spiritual gift to make them strong and that they might be encouraged by each other’s faith. Paul said, “I do not want you to be unaware, brothers, that I planned many times to come to you (but have been prevented from doing so until now) in order that I might have a harvest among you, just as I have had among the other Gentiles. I am obligated both to Greeks and non–Greeks, both to the wise and the foolish. That is why I am so eager to preach the gospel also to you who are at Rome” (Romans 1:13-15 NIV). I understand Paul feeling obligated to both Greeks and non-Greeks, but I’m trying to wrap my head around his obligation to the wise and the foolish.
