I believe the Bible is clear on this issue - but it is one that needs to be studied out.

What is the purpose of the Tribulation? Who are the primary characters in it? Why is the church not mentioned during the Tribulation events in the book of Revelation, and what is Revelation 1:19 and 4:1 teaching/referring to?

Who is this a promise to, and what is it a promise about:

Revelation 3:10 Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
