Mark 13:22-30

22for there shall arise false Christs and false prophets, and shall show signs and wonders, that they may lead astray, if possible, the elect. 23But take ye heed: behold, I have told you all things beforehand.

24But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, 25and the stars shall be falling from heaven, and the powers that are in the heavens shall be shaken. 26And then shall they see the Son of man coming in clouds with great power and glory. 27And then shall he send forth the angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.

28Now from the fig tree learn her parable: when her branch is now become tender, and putteth forth its leaves, ye know that the summer is nigh; 29even so ye also, when ye see these things coming to pass, know ye that he is nigh, even at the doors. 30Verily I say unto you, This generation shall not pass away, until all these things be accomplished.
