By the things that are without, the apostle meaneth either those evils which happened to him from persons that had nto relation to the Christian church, but were persons without, ( as the phrase is used, 1Co_5:13), or else such kinds of troubles and afflictions as very little influenced his mind, but only affected his outward man: such were his labours, travels, journeyings, imprisonment, stripes before mentioned.
Beside these (he saith) there lay upon him an inward care and solicitude for
all the Christian churches; and this was a daily care. For an apostle differed from an ordinary pastor, not only in his immediate call from Christ, but also in his work; there lay an obligation upon such to go up and down preaching the gospel, and they further had, both a power, and also an obligation, to superintend all other churches, and to direct the affairs of them relating to order and government: and thereupon they were mightily concerned about their doing well or ill.
