Understanding your sheepness
"Without knowledge of self, there is no knowledge of God." (John Calvin, opening passage of The Institutes)
"When [Jesus] went ashore he saw a great crowd, and he had compassion on them, because they were like sheep without a shepherd. And he began to teach them many things." (Mark 6:34)
"I am the good shepherd. The good shepherd lays down his life for the sheep." (Jesus - John 10:11)
If you don't know that you are a sheep, then you will never feel the need for a shepherd. And thus, the gospel is lost on you.
