Mark 13:20, 22, 27

Unless the Lord had shortened those days, no life would have been saved; but for the sake of the elect, whom He chose, He shortened the days.

for false Christs and false prophets will arise, and will show signs and wonders, in order to lead astray, if possible, the elect.

And then He will send forth the angels, and will gather together His elect from the four winds, from the farthest end of the earth to the farthest end of heaven.
