I had not only a call to my apostleship, (of which indeed you were no witnesses), but I amongst you evidenced my call by such signs, as were sufficient to declare me to you to be a true apostle. Amongst these, he reckons: 1. Patience;
2. Mircles. The first refers to those many labours which he had, in travelling to propagate the gospel, in preaching, writing, &c.; this manifested him called of God to the work.
2. Miraculous operations were another sign; for though the working of miracles was not restrained to the apostolical office, yet when they were wrought in confirmation of the doctrine which the apostle had first preached, and so were a seal of his ministry, they were truly signs of his apostleship; it being no way probable, that the God of truth would have communicated his power to men for the confirmation of lies, or of an employment to which he had never called them.
