serenity: the state or quality of being calm, tranquil, at peace
The main prayer we will use to begin our classes each month will be the Serenity Prayer. It's short and simple, but I have found it to be very helpful in my weakest or most stressful moments.
God grant me the serenity to accept the things I cannot change,
the courage to change the things I can,
and the wisdom to know the difference.
