Fear of the unknown is one of the greatest causes of worry.  In fact, the fear of fear is often worse than the fear itself.  We worry about the what if’s and the when’s to the point that our minds grow numb and our vision goes faint.  In Luke 21, Jesus teaches us to “Know and Watch.”  Christians know that the troubles of today are temporary and not beyond the arm of God. So, we stay alert and watch with expectation for the day when the son of man comes again to make all things new.
