Mr. Know-It-All

I taught at a high school that had not one, not two but three men who acted as if they knew everything. There was not a subject that they were not an expert. Someone asked me one time what it was like to work with such authorities.
When I thought about knowledge I thought about the purpose of knowledge. Knowledge is not an end in itself but rather a means to an end. By knowledge we get to know God.
Knowledge has two ugly step sisters. One is called pride who says look at me and what I know, I must be special. Then there is her green eyed sister who is called envy. She says why does that person have more knowledge than I have. When we know that the purpose of knowledge is to know God then there is no room for pride or envy.
