(Pro 14:8 KJV) The wisdom of the prudent is to understand his way: but the folly of fools is deceit.
A well known aphorism is “Know thyself.” That is what Solomon is saying in his own way. One of the aspects of “wisdom” (2451) is self understanding. We have the luxury of knowing what is going on in our own minds and hearts. We can read our own motives. Others may judge us but we can know if we were being righteous or pious.
Start there. Self honesty is important and necessary. You don’ need to tell anyone else, just yourself and God.
Implied in this is that it is possible to know yourself. Always. Ignorance is a choice, not a necessity. “Fools” (3684) tend to not even be honest with themselves. That is truly a sad state of affairs when a person thinks they can pull the wool over their own eyes.
So? Spend some time in introspection. Examine your heart. Get to know the real you. If it isn’t the person you want to meet, then talk to Jesus about a new heart.
