Matthew 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
There are three rationale ways to interpret verse 22.
1. The length of each day shortened to be less than 24 hours, at some point during the great tribulation.
2. The number of days of the great tribulation reduced from the original length of 1335 days.
3. The length of great tribulation limited to 1335 days. Any longer and no flesh on earth shall survive.
Personally, I think way 3.
