But you shall receive power, after that the Holy Ghost is come on you: and you shall be witnesses to me both in Jerusalem…
Here at one end is the great fountain ever brimming. Draw from it ever so much, it sinks not one hair's-breadth in its pure basin. Here, on the other side, is an intermittent flow, sometimes in scanty driblets, sometimes in painful drops, sometimes more full and free, on the pastures of the wilderness. Wherefore these jerks and spasms? It must be something stopping the pipe. Yes, of course. God's might is ever the same, but our capacity of receiving and transmitting that might varies, and with it varies the energy with which that unchanging power is exerted in the world.
(A. Maclaren, D. D)
Parallel VersesKJV: But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
