Proverbs 1:7

The fear of the Lord is the beginning of knowledge, but fools despise wisdom and instruction.

A lot of times, a fool is just someone who wants their own way and doesn’t listen to the counsel of the Lord.  The fear of the Lord is about reverence for Him and His ways.  We can never learn from God if we are unwilling to listen to Him. Just like in school or anywhere else, we have to learn and get revelation than we change.  Without instruction, we will never gain wisdom.
