Perspective? How do you "See" and "Hear"?

Proverbs 3:5-6
Trust in the LORD with all your heart. Never rely on what you think you know, your own perspective, and understanding. In all your ways acknowledge and recognize Him, and He will make straight your paths.

Luke 8:18
So pay attention to “how” you hear. To those who listen to my guidance, more understanding will be given. But for those who are not listening, even what they think they understand will be taken away from them.
