In this message Peter looks at some of the dumb characters who appear throughout the book Proverbs, namely: the secret sinner, the loose woman, the stupid speaker, the unrestrained fool, and the presumptions fool. Here the Bible teaches us to learn from the mistakes of others: "A wise man learns by the experience of others. An ordinary man learns by his own experience. A fool learns by nobody's experience."
12 Let a man meet a she-bear robbed of her cubs
rather than a fool in his folly. (ESV)
