What is faith?

This is a quick commentary on a couple of verses found in the bible dealing with the subject of faith. I am a Christian so the faith I speak of is faith in Jesus Christ. It's a good review on what faith really is, the importance of it, how to gain it, and how to grow it. Hope you enjoy, love you all and remember:
"Without faith it is impossible to please God." -Hebrews 11:6
