AS HEARING LOSS

A man asked, "What of wisdom? Has this not been plentiful in the world since the days of the Great Enlighteners, of whom Solomon was deemed the greatest?

Even before him, there was much wisdom, yet is Earth a better place for this?

What has it contributed to progress?"

Jesus replied, "Alas, never has there been a shortage of wisdom in the world, but always there has been too little in the hearts of men.

Wisdom is not something written in books, but that, which is conveyed from the book of the heart.

It is a way of life."
