Meaning of “folly”

Could you please explain the meaning of the word "folly" which is in Mark 7:22, and also what may be some current examples of this in our society? Thank you.

The meaning of the Greek word is “foolishness, lack of sense: moral and intellectual.”

We can find current examples of this in our society simply by looking at the sins Jesus mentioned in Mark 7:21-22. The commission of those sins indicates a lack of moral sense. As Jesus pointed out, such sins flow from within—from hearts that are sinful by nature.

This is why we confess that we are naturally sinful and that we have sinned against God by our thoughts and words and deeds. Through the power of the Holy Spirit, we also confess that we have forgiveness for our sins through Jesus, who lived perfectly in our place and endured the punishment our sins deserved.
