“If those days
Had not been
Cut short,
No one
Would be saved.
But for the sake
Of the elect,
Those days
Will be cut short.”
καὶ εἰ μὴ ἐκολοβώθησαν αἱ ἡμέραι ἐκεῖναι, οὐκ ἂν ἐσώθη πᾶσα σάρξ· διὰ δὲ τοὺς ἐκλεκτοὺς κολοβωθήσονται αἱ ἡμέραι ἐκεῖναι.
There is something similar in Mark, chapter 13:20, but not in Luke. Jesus said that if those days had not been cut short (καὶ εἰ μὴ ἐκολοβώθησαν αἱ ἡμέραι ἐκεῖναι), no one would be saved (οὐκ ἂν ἐσώθη πᾶσα σάρξ). However, for the sake of the elect or chosen ones (διὰ δὲ τοὺς ἐκλεκτοὺς), those days will be cut short (κολοβωθήσονται αἱ ἡμέραι ἐκεῖναι). There will be less suffering at the end times because God does not want his chosen elected ones to suffer too much.
