Of course it is Jesus as you will observe by the power of His words He will judged the nations from the 1260th to the 1290th day. He will set up Israel as the center of all nations from the 1290th to the 1335th day. And He will reign in the 3rd Temple in Jerusalem. He will reign over the nations with a rod of iron with His overcomers that had died and now resurrected alive reigning with Him. Is that not enough to convince you?It is indeed the Jewish believe that the Messiah is to be expected on Tisha Be'av.
Whether it's Jesus or not, that's the million dollar question
That some will still reject Him shows that the reason why He reigns with a rod of iron is because we will ruling over people who are not saved.
Is it not enough to convince me?
If I let you convince me, it would be like I go against my values and religion, and that's something any sane Jewish person cannot afford. How can I believe another Jew is an offspring of God, more than any other? That's the disagreement between Christianity and Judaism.
Anyway, why you speak of God of a being that dooms and scares others so much? that's the way you see God? why?
