Jesus began to reproach the towns in which most of his miracles had been worked, because they refused to repent.
‘Alas for you, Chorazin! Alas for you, Bethsaida! For if the miracles done in you had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. And still, I tell you that it will not go as hard on Judgement day with Tyre and Sidon as with you. And as for you, Capernaum, did you want to be exalted as high as heaven? You shall be thrown down to hell. For if the miracles done in you had been done in Sodom, it would have been standing yet. And still, I tell you that it will not go as hard with the land of Sodom on Judgement day as with you.’

TO JUDGE THE LIVING AND THE DEAD
678 Following in the steps of the prophets and John the Baptist, Jesus announced the judgment of the Last Day in his preaching. Then will the conduct of each one and the secrets of hearts be brought to light. Then will the culpable unbelief that counted the offer of God’s grace as nothing be condemned. Our attitude to our neighbor will disclose acceptance or refusal of grace and divine love. On the Last Day Jesus will say: “Truly I say to you, as you did it to one of the least of these my brethren, you did it to me.”
679 Christ is Lord of eternal life. Full right to pass definitive judgment on the works and hearts of men belongs to him as redeemer of the world. He “acquired” this right by his cross. The Father has given “all judgment to the Son”. Yet the Son did not come to judge, but to save and to give the life he has in himself. By rejecting grace in this life, one already judges oneself, receives according to one’s works, and can even condemn oneself for all eternity by rejecting the Spirit of love.
