In answering this question we must take a look at it from several perspectives. First, lets look at a fool from the perspective of their basic beliefs. According to Proverbs 1:7, fools despise wisdom and instruction. It reminds me of someone I heard saying, “I’m my own boss, no one is going to tell me. . . ” They are wise in their own eyes and do not see their own limitations and needs. They are blind to the rest of reality. Proverbs 1:22 adds that they hate knowledge. Conflicting facts are unimportant and easily dismissed. Because of this they create blind spots that later surprise them with abrupt reality that often is painful. In Proverbs 10:21 fools die for want of wisdom. In other words, they are stubborned and are not easily turned or reasoned with. A fool is so set in his way that it is an abomination for him to depart from evil. (Prov 13:19) Pr 14:8 The wisdom of the prudent is to understand his way: but the folly of fools is deceit. Some synonyms for folly are: stupidity, silliness, madness, craziness, lunacy, and ridiculousness. Synonyms for deceit are:fraud, cheating, trickery, pretense, treachery, deception, cheat, fake, and misrepresentation or simply lying. Their methodology is unfair and unreasonable and one sided. It is a stacked deck against you so that you cannot win. Ecclesiastes 7:4 The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth. Entertainment is the chief activity of the fool though it cost him dearly.
Now we need to look at the flaw of their basic beliefs. Psalms 107:17 Fools because of their transgression, and because of their iniquities, are afflicted. Transgression is a word that means to cross over the bounds, to infringe, overstepping, violation and defiance. Literally, to rob or steal from another. The fool has the philosophy that whats mine is mine and whats yours is mine. He is a taker and not a giver. The word, iniquities, means the twisting of the facts. He sees every situation in the light of what he can gain irrespective of the cost or pain. The fool has no concern for others.
A third perspective to be considered is the end. What is the final outcome of such a life? Our verse above states that they are afflicted. There is a cost to holding such a position in life and that is the affliction that comes with it. The fool is short sighted and does not see his end nor the consequence that such a life will certainly bring. Should you be persuaded to join them in their affairs, you will certainly share in its consequence, even though you may be otherwise minded on other issues. Another consequence of a fools, folly is shame (Proverbs 3:35) You will become the “bad example” for others to learn from. Fools are blinded to real values (Matthew 23:17), and as a result cannot see and therefore do not believe in the eternal. According to Proverbs 10:21 the fool dies for want of wisdom. Again in Proverbs 13:20 a companion of fools shall be destroyed. It is not a pretty end for the fool. Any gain will be lost but even worse the soul will be destroyed. Don’t be a fool.
