The proverb here tells us that what we speak will distinguish between those that are wise and those that are fools. Those that are wise will take information and properly apply that knowledge in such a way that when they speak, they impart words that are accurate, true, profound, helpful, insightful, etc. However, those that are fools, words of stupidity come flooding out of the mouth that are crass, inappropriate, worthless, and/or harmful.
You don’t have to be a rocket scientist to be wise because there are plenty intelligent fools out there. To be wise is to know the Lord, to know His Word, and to walk according to His ways. You spend your time doing that and I bet you would have some things worthy of sharing unlike 95 percent of the posts, tweets, and vlogs I come across these days.
