From troublesome, or importunate men. In the Greek, is signified men who act unreasonably, absurdly, &c. (Witham) — For all men have not faith. Faith is a gift of God, which he is not obliged to give but to whom he will. St. Paul here assures us that he finds nothing but obstacles in his great work, nothing but enemies of the truth, and nothing but men who resist the inspirations and calls of God, opposing the preaching of the gospel. He exhorts them not to be scandalized at what they see him suffer, but to return thanks to God, who has vouchsafed to call them, giving them an understanding and docile heart. (Calmet)
