Luke 17:22-25

And He said to the disciples, “The days will come when you will long to see one of the days of the Son of Man, and you will not see it. They will say to you, ‘Look there! Look here!’ Do not go away, and do not run after them. For just like the lightning, when it flashes out of one part of the sky, shines to the other part of the sky, so will the Son of Man be in His day. But first He must suffer many things and be rejected by this generation.
