But ye shall receive power, after that the Holy Ghost is come upon you; not till then, not of their own strength, but of God's grace, as appeared by Peter's denying and the others leaving of our Saviour. And ye shall be witnesses unto me, that I am indeed the promised Messiah; and of my doctrine, life, death, resurrection, and ascension, which ye shall testify to all the world by your preaching and holy living, working miracles. Both in Jerusalem, and in all Judea, and in Samaria; places where your testimony shall be most opposed. These words are both a command, to tell the apostles what they ought to do, and a prediction of what they should be enabled to do.
