Another place to start might be the book The Late, Great Planet Earth by Hal Lindsey. This was a very popular book in the early '70s.
Hal Lindsey was wrong about the entire church being raptured pre-tribulation.
If you take this analysis of the end times you will have a good picture of the
matter.
But the interest Brother Lindsey sparked by his book was good.
Most of the passages about the Lord taking some from the earth are conditional in
nature.
Ie. Because THIS condition was meant THIS taking away is the result.
IE. IF you will fulfill THIS requirement THIS taking away will be the result.
The verses are conditional rather than automatic.
And if they are conditional then it is logical that some will heed and some will not.
Then you have to consider who is the audience of exhortations - the world at large or the circle of
Christian believers. I think you have to consider that the recipients of the promises are Christians and not the world in general.
"Remember Lot's wife. Whoever seeks to preserve his soul-life will lose it, and whoever loses it will preserve it alive.
I tell you, In that night there will be two on one bed; the one will be taken but the other will be left."
What is the best interpretation?
Is the
"two" two unbelievers? Certainly not.
Is the two
"two" a believer and a non-believer?
More likely but probably not.
