"The 6th trump, only one third are killed. Matthew 24:37-
39, compares the event to the days of Noah where all of
the evil are taken away. Shall we distinguish
between "some" and "all?"
I'm not certain of your question. You're probably going much deeper than I can but I would love to know exactly what you mean. "shall we distinguish between some and all"?
I believe that scripture is not careless when it comes to details. It is able to foresee the things that God will do. (Gal 3:8)
"The “one taken and the other left,” in Matt. 24:41,42 is referenced to the days of Noah, (Vs.37) where all of the evil ones, that know not, are taken. You say that there is a connection to the sixth trumpet in Revelation 9, where some are killed.(not taken) These two events are sufficiently different to raise a flag.
Consider that if God set up the days of Noah as a metaphor, then we can hold the metaphor to a standard of perfection, simply because it is from God. The fact that they were eating , drinking, marrying and giving in marriage and not worried about the impending judgment is hard to parallel what the attitude will be by the time we arrive at the sixth trumpet.
Matthew 24: when some are taken is at the 6th trump, when Satan comes
Satan has not left, how can he come back?
