In today's society, at least in this country (USA), people know so much, kids included. After all, this is the information age. What's sad to see is that so many people talk as if they know everything! They are opinionated, vocal, and even boastful. Showing some humility couldn't be further from their minds. They are not even aware that they are being self-centered and foolish in God's eyes. The knowledge of the world can be as dangerous as other things of the world that blind us from seeing God.
