Luke 17:22-24

Then he said to his disciples, “The time is coming when you will long to see the day when the Son of Man returns, but you won’t see it. People will tell you, ‘Look, there is the Son of Man,’ or ‘Here he is,’ but don’t go out and follow them. For as the lightning flashes and lights up the sky from one end to the other, so it will be on the day when the Son of Man comes.
