Great tribulation will be severe but limited for the sake of the elect.

²¹For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.

²²And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened.

¹⁹For 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.

²⁰And 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.
