"And this gospel of the kingdom shall be
preached in all the world for a witness
unto all nations; and then shall the end
come," Matthew 24:14

The Bible doesn't teach that Jesus cannot
come in the Rapture until the Gospel is
preached to the whole world. Rather, it
teaches that the Gospel of the Kingdom
shall be preached to the whole world.

Then shall the end.....the end of man's day
and the return of Jesus and His Kingdom
reign.....come after the Gospel of the Kingdom
is preached to the whole world.
