I am surprised a bit, that even Bill Wilson is now talking about what will happen to the world now. It all boils down to what we Christians are in the "Heart" department/ area. As imperfect, sinful human beings, it is not for us to know that exact time that Jesus will come back to scoop up His servants and Believers.
As we watch "Survival" TV programs, reality stuff, we learn how much punishment the human body can take, and also sleep and food deprivation. It's also important to find out that we need our Faith in God Almighty, not just food and water to survive. The KJV Bible holds all the direction, instruction and spiritual nourishment that we need to make it to the end.
