Treasures are stored in the heart of man, weather good or evil. Guard what you see with your eyes. Protect what you hear with your ears. It’s like a feeding tube it enter one way an flows out another.

⁴⁵ A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.

Luke 6:45 (KJV)

⁴⁶ And why call ye me, Lord, Lord, and do not the things which I say?
