Jesus speaks of the Tribulation saints as
His elect. "They shall gather together His
elect."

They are gathered together at the end of
the Tribulation, just before God's wrath is
poured out.

In Luke 18:7-8 He refers to His elect at
His coming.
"And shall not God avenge his own elect,
which cry day and night unto him, though
he bear long with them?
I tell you that he will avenge them speedily.
Nevertheless when the Son of man cometh,
shall he find faith on the earth?"
