Quite a bit actually. Ever hear someone say, "knowledge is power"? Many of us have.
If someone said, a full glass of water quenches your thirst, would they be right? Think about that for a moment. Does the full glass quench your thirst or does emptying the glass by drinking it quench your thirst. Ah... I think we're getting somewhere.
Knowing something is like filling up your glass. If knowledge stays in the glass, then it has no power and can never quench your thirst to be successful. However, if you take that glass filled with knowledge and apply it to your lips and consume it - well, you've just gone from knowing something to seeing the effects it has on your life.
The book of Proverbs has a lot to say about this very thing.
