What is the author saying????
He is saying to keep evil thoughts, sinful thoughts, things your eyes should not be looking upon which enters into the heart, out of your life and your heart.
Keep your heart, your thoughts, your mind PURE and FREE of sinful LUSTS and thoughts.
It is IMPOSSIBLE to have FELLOWSHIP with a holy GOD when you have DIRT in closet, which is where HE meets you at!
The closer you get to the light, the easier it is to see the dirt!
