It is the presence of the divine Spirit, the water of life, that prevents the consuming thirst of mortal discontent and that indescribable hunger of the unspiritualized human mind. Spirit-motivated beings "never thirst, for this spiritual water shall be in them a well of satisfaction springing up into life everlasting." Such divinely watered souls are all but independent of material environment as regards the joys of living and the satisfactions of earthly existence. They are spiritually illuminated and refreshed, morally strengthened and endowed. 34:6.8
