What it would take is a crisis of world wide proportions. Lets say a financial depression with food shortages across the globe. People rioting. The governments of the world would need a solution and then someone comes on the scene that appears to have the answers. I not only feel it can happen I believe it will happen. That is because I am Christian an have read the book. As far as I am concerned it is a done deal. The only question is how soon, but anyone that has studied scripture would have to agree that a lot of what is happening in our country and the rest of the world in light of what is written is a little uncanny to say the least. Just my 2 cents worth.
