When airlines train new pilots, they test them in a simulator. This simulator presents them with problems and malfunctions they might face in a flight. The problems start out small and progress to the most severe. Only after they master dealing with the small ones do they move onto the most severe ones. This is the same way God teaches us to handle the problems of life. He teaches us through every situation so that we can be prepared and ready to handle any challenge we may face in the future that might come our way all the while never giving us more than we can handle.
