'Mighty' in the Bible

Many will say to Me on that day [when I judge them], ‘Lord, Lord, have we not prophesied in Your name, and driven out demons in Your name, and done many miracles in Your name?’

Then He began to denounce [the people in] the cities in which most of His miracles were done, because they did not repent [and change their hearts and lives].

“Woe (judgment is coming) to you, Chorazin! Woe to you, Bethsaida! For if the miracles done in you had been done in Tyre and Sidon [cities of the Gentiles], they would have repented long ago in sackcloth and ashes [their hearts would have been changed and they would have expressed sorrow for their sin and rebellion against God].

And you, Capernaum, are you to be exalted to heaven [for your apathy and unresponsiveness]? You will descend to Hades (the realm of the dead); for if the miracles done in you had been done in Sodom, it would have remained until this day.
