“Even the very dust of your city that cleaveth to us, we wipe off against you. Yet know this, that the kingdom of God is at hand. I say to you, it shall be more tolerable at that day for Sodom, than for that city. Woe to thee, Corozain, woe to thee, Bethsaida. For if in Tyre and Sidon had been wrought the mighty works that have been wrought in you, they would have done penance long ago, sitting in sackcloth and ashes. But it shall be more tolerable for Tyre and Sidon at the judgement, than for you. And thou, Capharnaum, which art exalted unto heaven, thou shalt be thrust down to hell.”
[Luke 10: 11-15]
Also, He was still living in the Old Covenant and had not shed His blood that the sins of others might be washed away if they decided to accept Him.
