Most teachers follow the rule that if one student asks a question, more than one student is thinking the same question. So when I repeatedly get asked one question, I know that it is time to rephrase the answer I have been giving and try to explain it more fully.
The question I get concerns our teaching that only about 20% of the Israelites left Egypt. I understand that this isn’t part of general Sunday School lessons, but that is because it is a message for adults with enormous implications.
In fact, the Italian economist, Vilfredo Pareto, is credited with popularizing this eighty-twenty principle although I have no idea if he knew that it is found in the Bible. There are plenty of examples of this rule that will set your head nodding.
If you enjoy cooking or baking, you probably use about 20% of your recipes 80% of the time. You probably wear about 20% of your clothing 80% of the time. Perhaps about 80% of your social connectivity comes from interactions with only 20% of your friends. Those in sales know that about 80% of their sales revenue comes from 20% of your customers.
