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.
This Church seems to have found favor with The Lord and he promises to keep them out of the tribulation altogether. Who would be a member of this church today, and are they the ones whom will be raptured? If you don't believe in the rapture, then what does this verse imply to you?
This is a main reason one can know these are not "church ages" but existent churches of the day in which John is writing.
The "hour of temptation" that is coming upon all the world, is the coming intensification of the tribulation Jesus spoke of. Christians of that day were feeling the persecution as the Roman Empire demanded worship of Caesar. The Roman Empire is also about to have significant troubles because after the death of Nero during the span of Emperors Galba, Otho, and Vitellius Rome becomes extremely chaotic and nations attempt to break away from Rome at that time which causes war, conflict, and destabilization in the world scene of that day.
I believe the Caesar of this particular time is Nero who is the 6th king of Revelation 17:10. With all the thing that are forthcoming John wants them to know the world is about to become extremely chaotic. If they keep their focus on Jesus they will not come under the temptation that the world will face at that time.
When John speaks of "them that dwell on the earth" he's speaking not to us but of those that dwell on the earth at that time. Just as he is writing to those in the Church of Philadelphia at that time.
What we should be gaining from this message to that church is that just as the world could become and is becoming extremely chaotic today, if we maintain our focus on Jesus, we will be kept by God through such times.
There have been extremely trying times for the church throughout history and those that have maintained steadfast faith will endure it. That doesn't mean some instant rapture that pulls christian out of the world though. We are "in the world and not of the world"...and just as Peter, Paul, John and the other apostles had to endure their trials, we must endure our trials.
The rapture from tribulation is popular for that reason, in my view. However we have Christians enduring extreme persecution in the world today, and they're not being raptured. Their faith is being put to the test while we Christians in America enjoy freedom of worship...however, that too is disappearing.
The seven churches are churches of spiritual conditions. Those conditions exist in churches today. Try being a Christian in Iran, or try being a Palestinian Christian where you're hated by Muslims, and then you also have to deal with the injustice Palestinians do toward Israel and that Israel does against the Palestinians.
That's "an hour of temptation". Think about it...
