Luke 17:24

24 because the Son of Man in his day will be like lightning that flashes and lights up the sky from one horizon to the other.

Luke 17:24 In-Context

22 Then he said to his talmidim, "The time is coming when you will long to see even one of the days of the Son of Man, but you will not see it.
23 People will say to you, `Look! Right here!' or, `See! Over there!' Don't run off, don't follow them,
24 because the Son of Man in his day will be like lightning that flashes and lights up the sky from one horizon to the other.
25 But first he must endure horrible suffering and be rejected by this generation.
26 "Also, at the time of the Son of Man, it will be just as it was at the time of Noach.
