By H.H. Pope Shenouda III 
The greatest sign is that God's love in your heart  removes away everything, and nothing else may give you pleasure. All  the pleasures of the world have no taste compared to God's love.
 
 Everything seems trivial and insignificant as Wise  Solomon said, "All was vanity and grasping for the wind." (Eccl 2)  Therefore the more you grow in God's love, the more you disdain all  worldly pleasures and say with St. Paul the Apostle, "I have suffered  the loss of all things, and count them as rubbish, that I may gain  Christ and be found in Him." (Phil 3: 8)
 
 Imagine a professor of mathematics, shall he find  pleasure in small arithmetical calculation? They will seem to him very  trivial. The same applies to the worldly matters in the sight of whoever  is filled with God's love..
