The Text

“Foolishness is joy to one without sense, but a man of understanding walks a straight path.” — Proverbs 15:21

The Contrast Solomon Paints

• The fool: delights in reckless folly, enjoys the thrill of sin, ignores consequences (Proverbs 10:23; 14:9).

• The man of understanding: finds joy in staying on “a straight path,” living with moral clarity and purpose.
