Poor in whose eyes?

James 2:5 says this: "Listen, my dear brothers: Has not God chosen those who are poor in the eyes of the world to be rich in faith and to inherit the kingdom He promised to those who love Him?"
Today I am struck by the fact that some of the people here in Rio have so little, yet their joy and happiness is unbelievable. We as Americans have set our happiness in material things, and not in the love of God. These Brazilian believers are a wonderful example of finding joy -- not in material things, but in the knowledge that they are loved by God, no matter what.
