When airlines train their pilots they first test them in a simulator. The simulator is designed to present the pilot with a variety of potential problems so that they will be able to handle any emergency in the future. First the pilot is tested with simple challenges, which eventually build up to catastrophic situations. The pilots are given more difficult problems only when they have mastered the previous ones.
The result is that when the pilots have completed their courses, they are prepared to handle any problem that comes their way.
This is similar to God’s method of working with us. God teaches us how to handle the problems of life, but never gives us more than we can handle. He teaches us through each situation, so that we can be fully prepared and mature people, ready to handle any challenge in life that might come our way.
