Jesus's mission, in the flesh, was to save. But, it's His job to judge. And, judge he did. He did not forgave the Jews, but judged them in 70AD. He sent the Jews to join the the tribes of Israel already lost to history. That's what the Olivet Discourse about (not the end of the world).
Luke 21:22
because these are days of vengeance, so that all things which are written will be fulfilled.
Luke 19:43 For the days will come upon you when your enemies will throw up a barricade against you, and surround you and hem you in on every side, 44 and they will level you to the ground and your children within you, and they will not leave in you one stone upon another, because you did not recognize the time of your visitation.â€
