"Are you listening to me? Really listening?
"How can I account for this generation? The people have been like spoiled children whining to their parents,
'We wanted to skip rope, and you were always too tired; we wanted to talk, but you were always too busy.'

"Doom to you, Chorazin! Doom, Bethsaida! If Tyre and Sidon had seen half of the powerful miracles you have seen, they would have been on their knees in a minute.
At Judgment Day they'll get off easy compared to you.
And Capernaum! With all your peacock strutting, you are going to end up in the abyss. If the people of Sodom had had your chances, the city would still be around.
At Judgment Day they'll get off easy compared to you."
