The joy of the Lord is your strength.

One of the biggest differences in people is their level of enthusiasm
You can never rise to great heights without joy and enthusiasm Joy is a weapon that defeats sorrow and sadness  Joy and enthusiasm must be nourished with new actions, new aspirations, new efforts and vision Don't let your circumstances take away your Joy.  Nothing scares Satan than being oyful and thanking God in your troubles
              The joy of the Lord is your strength (Nehemiah 8:10)*_.
_My prayer for you is that you will never lack joy_.
