Because riches can buy only a very limited number of things. Jesus spoke of the deceitfulness of riches. Riches give us a feeling of power that we really don t have. They give us a feeling of being loved when we re not. Of being respected - when we re not respected.
Riches can t buy love and joy and peace and harmony.
Time after time we hear about rich people that would give everything they own for just a few moments of peace or joy. And you have my might at your disposal - greater than anything the world knows about. Boast in this Jeremiah. It would be easy to think that all this relates to someone else. But we all really need to hear this today.
