God won’t simply pull saints out of the coming troubles foretold in Revelation. His Angel, His active presence, surrounds those who fear Him, to deliver them, like the three men in Daniel 3 were kept alive by angelic power in a raging fiery furnace. The only reason they were in that furnace was their refusal to do a similar thing to taking the mark of the Beast, they refused to bow to an image of the king. They asserted bravely that even if God did not deliver them, they would still not bow to the idol. God decides whether to deliver, but His favour is in those who are righteous and who fear Him more than they fear mere men.
