Fools find no pleasure in understanding
Proverbs 18::2 NIV
but delight in airing their own opinions.
I’m sure you have met this person. The one who has an opinion about nearly everything. And who freely and boldly shares those opinions as if they were facts. They share, not to promote understanding; either for themselves or others. But simply because they want everyone to know what they believe. They delight in airing their own opinions.
Is it wrong to have opinions? Certainly not; we all have them. We have opinions about nearly everything we encounter. And sharing those opinions, if done correctly, is not wrong either. So long as we recognize that it is my opinion and not fact. And that others may have equally valid, although quite different, opinions on the same topic.
Solomon calls the person who delights in sharing their opinions a fool. Not because they are mentally deficient. On the contrary, they could be brilliant. In Proverbs, a fool is one who acts or speaks in ways that bring harm or discredit to themselves and others.
One way that the fool can gain wisdom is to listen and learn from others. You do not necessarily need to agree with them. But listen and try and understand. Pay attention to their feedback. It is just possible they might have something valuable to say. Something you might learn from.
