Matthew 11:23

And as for you, Capernaum. Capernaum was a city of 30,000. It may have been on the lake shore, at the ruins called Tell-Hum. It was the Galilean home of Christ, who taught in the streets and houses, and performed many miracles there. The people were very proud of themselves, but they will be thrown down to hell because they would not turn from their sins. Within forty years time, the Romans destroyed this city. Sodom. Note the implication: (1) Sodom was destroyed for its sins; (2) The knowledge that Capernaum had been given would have caused Sodom to repent and it would still be in existence; (3) It is sin that destroys cities and nations; (4) Modern cities and nations who deliberately live in sin and rebellion can expect to be thrown down to hell.
