Then He said to the disciples, "The days will come when you will desire to see one of the days of the Son of Man, and you will not see it.  And they will say to you, ‘Look here!’ or ‘Look there!’ Do not go after them or follow them.  For as the lightning that flashes out of one part under heaven shines to the other part under heaven, so also the Son of Man will be in His day."

Luke 17:22-24   (NKJV)
