The Rapture of the Church not only ends
the Church Age, but it begins the Day of
the Lord.

"But, beloved, be not ignorant of this one
thing, that one day is with the Lord as a
thousand years, and a thousand years as
one day.
The Lord is not slack concerning his promise,
as some men count slackness, but is long-
suffering toward us, not willing that any
should perish, but that all should come to
repentance.
But the day of the Lord will come as a thief
in the night, in which the heavens shall pass
away with a great noise, and the elements
shall melt with fervent heat; the earth also,
and the works that are in it, shall be burned
up." 2 Peter 3:8-10
