You don’t know that you don’t know. When you are not open to a deeper truth, you cannot expand what you know. You can’t know so long as your focus is giving your own opinions. You can’t know when you never consider that you might be wrong. You can’t know when you will not listen to a counterpoint. Truth about God is bigger than my small opinions; some other voice may help me. “Truth” that I think I know about circumstances, relationships, and general facts might change if I only knew how to listen. Opinions, not laced with humility, invariable are prone to “my truth is superior to yours.” Then you don’t know that you don’t know.
“Every man’s way is right in his own eyes, But the LORD weighs the hearts” (Proverbs 21:2 NASB).
