Only with Christ has authentic joy made its appearance and the only thing of ultimate importance in our lives is to learn to see and know Christ, the God of grace, the light and joy of the world. Our joy will be genuine only when it no longer depends on things that can be stripped from us and destroyed, and when it has its basis rather in those innermost depths of our existence which no worldly power can take from us. Every external loss should turn us back to these innermost depths and better dispose us for our true life. 

 -Pope Benedict XVI
