By reason of being employed for so many years, in preaching the Gospel from Jerusalem, round about to Illyricum; taking so large a compass to minister in, and striving to introduce, propagate, and spread the Gospel, where Christ was never named before: I have been much hindered from coming to you; or he had been often, and by many ways, and upon many accounts, hindered from coming to them; the frequent calls to different and distant places, and the great work of preaching the Gospel in those dark parts of the world, and settling churches there, which was upon his hands, prevented his giving them a visit at Rome, which he much and often desired: as in the preceding verses the apostle excuses his freedom of writing to this church, so here his long delay of coming to them, assigning the reason of it.
