Mat_24:22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
Mat_24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect
In my paradigm, the Church is not present for the 7 year Tribulation. That, I think, covers the "insomuch that, if it were possible, they shall deceive the very elect." We live in a world, already, that photshops and illusions truth. Islam scripture indicates that Christ will return with the 12th Iman, and that fake Christ will tell the world that Christianity was all wrong. And the Iman is superior above that fake Christ. Other speculations, which I find very credible are that this will be combined with actual, flesh and blood "aliens" (read demonic) will offer "free" energy and medical advances to corrupt God's image in humanity.
Getting back to economics, it is key here to the satanic plan. It needs to fail present economies and what are these economies based on? Ever hear petro dollar? Money is backed by nothing but paper, illusion. Economies are controlled by international bankers. The stats presently, are that over 90% of monies/assets are controlled by less than 1% of the world's population. You don't have to be brilliant to see where this is going. Anyone who opposes plans now in place will ruthlessly be taken down. Israel will have to flee after the 3 and a half year peace is broken. I don't think you will be able to pay higher taxes - either you convert or die. The demonic will come with holograms of their version of history. And it will all be very believable.
