When you think everything you do is great and undeserving of any criticism, you qualify as a fool. For the one who lives uncritically of their own choices in life - is bound to make some seriously dumb choices.
The way of a fool is right in his own eyes. This proverb speaks of the lifestyle and the consistent choices of a person. The one making these choices is called a fool. We run into the fool often in this book. The fool is the one who hates wisdom, walks in folly, who despises wisdom and morality. Indeed this man or woman is a fool. They so value their own thinking and way that they cannot see how wrong it is. Their fallen condition is not considered a reason to question what they think and how they live. They hate God's ways and paths - and consider only their own thinking as wisdom. He has a thought and immediately congratulates himself for how amazingly wise it is. He should follow through with that thought and give himself to doing it. At no time does he actually think that his thoughts need counsel or examination.
The wise man is the one who listens to counsel. He does not trust his own thinking because he knows that he is naturally selfish and self-centered. He wants counsel because he does not consider himself the end of all wisdom and learning. Pride goes before a fall and a foolish man who thinks his own thinking is supreme is definitely one who is prideful. The wise man wants differing opinions and view points because he knows that in an abundance of counsellors there is victory. He wants to know what others think because he knows he can get wisdom from everyone. His heart is not filled with self - so it has plenty of room for the thoughts of others.
"Follow your own heart," is the advice of the world. Yet, if we look at this proverb, we see that following such wisdom gives us way too much confidence in ourselves. What we need is the godly counsel of others around us who love the Lord, who are willing to tell us the truth, and who have our best interests in mind because their interests for us are to love, know, and follow the Lord.
