it was Winston Churchill who originally said; "Success is never final.  Failure is never fatal.  It's courage that counts."  As a believer you  have the power within you to control your fear and be courageous.  Joshua 1:9 says, "Be strong and courageous! Do not be afraid or discouraged.  For the Lord your God is with you wherever you go."  Take charge of yourself, take control of your fears, and exercise the fruit of self-control.
