Often we use synonyms to explain a word but sometimes, an antonym can express the meaning more clearly. That’s how I feel about the word calm.
I don’t think calm is best described as peace, serene or still. Although elements of those words do fit.
But for me, the meaning is captured more accurately when we see the opposite of calm as being overwhelmed.
It is when we feel unable to manage the situation, emotion or challenge we are facing. Calm is not the absence of uncertainty or stress. It is not the absence of waves in the ocean but the capacity to ride with them until we reach the shore or still waters.
Calm is a deeper level assurance that all is well.
So, we can find calm in a storm. We can find calm in the sadness. We can find calm in the calamity. Because calm is rooted in faith, hope and love.
