“To do evil is like sport to a fool,
But a man of understanding has wisdom” (Proverbs 10:23)
Contextually, this proverb is talking about religion—it is a discussion of the difference between a person who delights in living his life in sinful ways and one who realizes the value and pleasure of living a godly life.
The foolish person not only thrives on indulging in evil activities but also boasts about it and makes light of those who try to correct him, actually making a laughing matter out of sin.
A person of wisdom, on the other hand, makes life decisions in accordance with God’s word. He realizes the lasting value of those decisions in eternity as well as the wholesome quality they bring to the present life.
