Mark 13:24 (KJV)

For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be.

And except that the Lord had shortened those days, no flesh should be saved: but for the elect's sake, whom he hath chosen, he hath shortened the days.

And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not:

For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.

But take ye heed: behold, I have foretold you all things.

And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.

And then shall they see the Son of man coming in the clouds with great power and glory.

And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.

Now learn a parable of the fig tree; When her branch is yet tender, and putteth forth leaves, ye know that summer is near:

So ye in like manner, when ye shall see these things come to pass, know that it is nigh, even at the doors.
