Parable of Snake and Mouse
A man purchased a white mouse to use as food for his pet snake. He dropped the unsuspecting mouse into the snakes glass cage, where the snake was sleeping in a bed of sawdust. The tiny mouse had a serious problem on his hands. At any moment he could be swallowed alive. Obviously, the mouse needed to come up with a brilliant plan.
What did the terrified creature do? He quickly set up work covering the snake with sawdust chips until it was completely buried. With that, the mouse apparently thought he had solved his problem.
The solution, however, came from outside. The man took pity on the silly little mouse and removed him from the cage. No matter how hard we try to cover or deny our sinful nature, its fools work. Sin will eventually awake from sleep and shake off its cover. Were it not for the saving grace of the Masters hand, sin would eat us alive.
