Cultural Fear or Faith
American culture includes education that consists purely of being able to learn the right answers to certain questions, and to be able to pass a test on the matter. Proper education should be teaching people how to learn and ask questions that have not yet been answered.
American culture includes being punished for making mistakes, especially in work environments. Proper assessment of mistakes should test the culture for environmental circumstances that cause mistakes, and to teach people to learn from mistakes rather than to learn how to cover them up.
Frequently it seems to me that narratives indicate that Jesus taught His trainees how to do what He had just sent them out to do after they came back with real questions that were the results of making mistakes.
If you never make any mistakes because you never take any chances, you probably have not accomplished much. Faith has a greater desire for good results, fear has a greater desire to avoid punishment. Being awesome is being faith-full.
