Issue that I have with a lot of that stuff is it is almost impossible to tell how much is real, how much is exaggerated, and how much is simply conspiracy theorists propaganda.
Sure, some of it is fantasy, yet some is true. Depends on what has really been verified, while other issues are stretched.
As for conspiracy theories, Satan is not only the Father of lies, but he is also a master conspirator. He doesnt actually stand out there and say this is what Im doing, so get ready! but its always secret and manipulative actions that entangle others to do his will, unwittingly. He can even put bogus information out there, so that at some point, even the word conspiracy has an essence of fantasy tagged to everything, especially the things that are proven true. Propagating disinformation is another of his talents, and used well to put a smiley face on everything so we overlook it all.
The question is, what do we do when we encounter a truth in such theories? Do we build bomb shelters (though that may be a good idea), stack seven years of provisions and hide in our shelter? Or do we pray about it (to speak with God), and fulfill our role to be a restrainer in this world from such things happening to their fullest?
We, along with the Holy Spirit, I do believe are the restrainers in place to thwart the tide of dire plans. While we cant stop the planning of everything, because it will play into the tribulation as it is set, we can make today reasonably safe for the church so that we may continue to be a force to all this world in presenting the gospel to others by various ways. This is a status we certainly enjoy in the US, that we can simply jump on a jet and take the gospel to a foreign land, along with real relief supplies and such.
If all this stuff overtakes us, if even 1/10th is accurate and we do nothing about it, how much could the restrainer be restrained here on earth? But I tell you, there will come a point when the restrainer will be taken from this earth, and we shall watch the dealings of the tribulation form the balconies of Heaven. But until that day, we are an occupying force on this earth, and we must keep watch, doing what we must to restrain these things from overtaking us today.
