The life of those “left behind” will not be a pleasant one. Those who will be shocked to realize that the disappearance of millions and finally understand that Christ indeed was the only way and turn to Him will need to understand that death will be their only way. Attempting to “go with the flow” and survive will result in damnation. The call is to turn to Jesus now. Not Jesus and something else but Jesus alone.
You've been reading way too much Tim LaHaye. That's fiction, not reality.
