Every call we make for tomorrow’s service is us calling for more empty vessels...like that widow, we know if we can get more empty vessels then, He will pour himself more and more. The real harbinger of revival is not a good preacher or a good singer; it is the amount of our collected hunger. So we can say 'Lord, here is another empty vessel, take and fill, there's another right there, when you are done filling that one, there's another waiting right here Lord’.
