Yes, indeed. A best school of life is show and tell. Let's take a child who thinks, visualization looking at a master creating a “wooden shoe”. It begins by explanation, putting in his hands, starting with simple process step by step until by increasing operations till a young person handle it on its own. This fifteen years old Michael went through three years of apprentice passed the exam, then continued working/improving for several years till mastering the craft, passing a rigorous exam thus becoming a master of this particular craft.
Another historical proof of show and tell in which the Man of Nazareth for three years "trained" these twelve learners to be like Him, to live modest life similar to the original man's creation before time of disobedience.
