Satan warms himself at the fire!
(Thomas Watson, "Doctrine of Repentance")
"Fools make a mock at sin!" Proverbs 14:9
Sin is a foolish thing. What greater foolishness is there, than to gratify an enemy! Sin gratifies Satan. When lust or anger burn in the soul — Satan warms himself at the fire! Men's sins feast the devil.
Samson was called out to amuse the Philistines. Likewise the sinner amuses the devil! Nothing more satisfies him — than to see men sin. How he laughs to see them hazarding their souls for the world — as if one would trade diamonds for straws; or would fish for gudgeons with golden hooks!
Every wicked man shall be indicted as a fool, at the day of judgment. "But God said to him — You fool! This very night your life will be demanded from you!" Luke 12:20
