Coming of the Son of Man

"For as the lightning goeth out of the east, and shineth even to the west, so shall also be the coming of the Son of man" (Matt. 24:27).

Calvin handles this coming of the Son of Man by saying, "The light of the gospel, as soon as it appear, darted from one side of the world to the opposite side like lightning." I may not be comfortable explaining what the coming referred to is, but I don't think his interpretation is without prejudice.  Frustratingly forced, really.
