Luke 21:25-27

25“There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. 26People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 27At that time they will see the Son of Man coming in a cloud with power and great glory.
