To “be still” in the presence of shaking earth, falling mountains and roaring seas is not the natural response to natural disasters, unless being still is fainting dead away. In the same way that the uncertainty of nations in uproar and falling kingdoms typically lead us to circle the wagons and prepare for the worst by doing our best to make sure our piece of the earth doesn’t melt away. But the command is to “be still” while God does the heavy lifting of breaking bows and shattering spears. Being still in the face of personal and collective calamity only happens if we stand still on the foundation of faith which is the “know I am God” part of the equation. So being still doesn’t lead us to know God as much as knowing God allows us to be still.
