(Proverbs 26:11 KJV) As a dog returneth to his vomit, so a fool returneth to his folly.
The shaping of a “fool” (3684) is not the mistake but that he “repeats” (8138) his mistake. A fool can’t seem to learn. You have heard the saying, “Fool me once, shame on you. Fool me twice, shame on me.”
Why don’t people learn?
Some are just too slow mentally to retain things. These kind of people exist. Admit it. Accept it. They are not common enough to explain fools. Similar to this are the people who are not developmentally ready to learn something. Young children cannot think abstractly. That is normal. They will grow out of it.
Some might actually have a learning disorder. These people also exist. The ugly secret is that they are not as common as public education makes you want to believe. Many times we simply make excuses for people or refuse to discipline children. It is often easier to label a child hyperactive and drug him than it is to apply consistent discipline.
Some are simply committed to sin and refuse to learn because that would mean they must change.
So? Keep in mind that “I didn’t know” will not be a very good defense on judgment day because God can see your mind and heart. Don’t be a fool. The choice may be up to you.
