As my Father hath sent me, &c.— "As my heavenly Father sent me into the world, to discharge the office of the Messiah; even so I, by my plenary authority, and in proof of my mediatorial commission, send you to discharge the office of apostles and ministers in preaching the gospel to every creature, and to confirm it with miraculous signs wherever you may go." See Mark 16:15; Mark 16:17-18.
