Matthew 24

14 And this good news of the kingdom will be proclaimed in the whole inhabited earth as a witness to all the ethnic nations, and then the end will come.*The ‘end’ of what? There are at least four possible relevant ends here—of the world, of the Millennium, of the Great Tribulation, of the Church Age. Just as this day, this week, this month, this year, etc. all have ends, but those ends are rarely coincidental, so the four ends above are not coincidental. So which ‘end’ is it? The immediately following context points to the Great Tribulation. In that event, any unreached ethnic nations in our day cannot impede the Rapture, since the angel in Revelation 14:6 will finish the job.
