What does Proverbs 9:16 mean?

Folly (Proverbs 9:13–15), the opposite of Wisdom (Proverbs 9:1–6), uses similar tactics and calls to many of the same people. Here she is seen attempting to influence those who are gullible and lack sense. However, while Wisdom encourages people to seek life and success (Proverbs 9:10–12), Folly looks to trap people in a vastly different destiny. Lady Wisdom calls the simple and those lacking sense to receive wisdom, learning, and abundant life. Woman Folly calls her audience to engage in sin.

Wisdom wants to build up her audience; Folly wants to bring down hers. Of course, Folly pretends to give her audience pleasure, but she is deceptive. Only trouble awaits those that heed her call. In his attempt to lure men and women into false teaching and sin, Satan uses false apostles who are deceitful workmen. They disguise themselves as the apostles of Christ (2 Corinthians 11:13), and "Satan disguises himself as an angel of light" (2 Corinthians 11:14). Jesus warned: "Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves" (Matthew 7:15).
