Jesus warned us, "Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt ... For where your treasure is, there will your heart be also." Desire creates your universe, that's just the way it works. So your first job is to work on yourself. The greatest thing you can do for another human being is to get your own house in order and find your true spiritual heart.
