Do you mean like, why isn't he a Jewish diety?  Because the Jews don't believe he was the Messiah

The Jews back in Jesus's day were actually really pissed at the dude most of the time because a big part of his message was basically  "none of these stupid traditions and all these rituals matter, all that really matters is love, trust me, I'm God's son!"

and people, especially leaders, of the Jewish faith often found that very blasphemous

I’d also like to add to this that Jewish peoples were oppressed by the Roman Empire at the time. A lot of Jews wanted the messiah to come and deliver them to freedom by taking vengeance on the Romans. So when Jesus arrived claiming to be the messiah and son of God, but his message was mainly about peace and turning the other cheek and all of that, the Jews rejected him. Because how could the son of the God who promised that the Jewish people were his chosen people preach non-violence in a time when Jews were so persecuted.
