Pope Shenouda III
Make sure that fasting changes something in you.
Do not let a change of food be the only thing different you do in a fast. Let the fast be change towards a better life, a chance to remove the defects and weaknesses you feel exist in your relationship with God and people. What benefit otherwise would you have, if you subdued yourself during the fifty five days of Lent only to come out of it exactly as you had been before, without increasing your fellowship and communication with God?!
