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..
