Can We Tell the Difference?

It seems like a good time to ponder Ecclesiastes, a reminder of the vanity and emptiness of so much of what we value - the present distress ought to cause us to recalibrate our priorities, but I fear it hasn't.

Here's a quote to ponder...I wonder if we can tell the difference between a wise person and a foolish person. Between a wise leader and a foolish leader.

"Words from the mouth of a wise man are gracious, while the lips of a fool consume him; the beginning of his talking is folly and the end of it it wicked madness." Ecc. 10:12 - 13.

What do you think? Can we tell the difference? Can I ? Can you?
