True contentment comes from Godliness in the heart, not from wealth in the hand.

From Philippians 4:11-13:  “For I have learned to be content with whatever I have.  I know what it is to have little, and I know what it is to have plenty.  In any and all circumstances I have learned the secret of being well-fed and of going hungry, of having plenty and of being in need.  I can do all things through Him who strengthens me.
