We need to be careful about our possessiveness. Nothing that we gain in this life lasts into the next except our relationships, especially our relationship with our Lord.
This is a lesson that has always caused me difficulty, for I am certainly too enchanted by trappings of this world. I focus more on worldly treasures than spiritual gains even though I know full well that once I have what I want at the moment, I will soon be desiring something else.
Only a desire for God is ever truly satisfied.
