"Why do you speak to the crowd in parables?"
He said to them in reply,
"Because knowledge of the mysteries of the Kingdom of heaven
has been granted to you, but to them it has not been granted.
To anyone who has, more will be given and he will grow rich;
from anyone who has not, even what he has will be taken away.
This is why I speak to them in parables, because
they look but do not see and hear but do not listen or understand.
Read that last line again. AHA moment, capisce?
