Dwight L. Moody once to his audience, "Tell me, how can I get the air out of the tumbler (glass) I have in my hand?" One man said, "Suck it out with a pump." The evangelist replied, "That would create a vacuum and shatter it." Finally, after many futile suggestions, Moody picked up a pitcher and filled the glass with water. "There," he said, "all the air is now removed." He then explained that victory for the child of God does not come by working hard to eliminate destructive thoughts and habits, but rather by allowing the Holy Spirit to take full possession.
