Jews don’t proselytize. I think it’s actually the best aspect of their religion: they never ring my door to talk to me about our lord and savior. More seriously they have this idea that more than coreligionaries they are a people: you are born into Judaism. Although you can convert to Judaism but it has to come from you and you have to study a lot and it is actually really hard. The few people who do it mostly do it to get married to a practicing Jew.
Then there is the historical context: Islam and Christianity expanded around the world through conquest, invasions and colonialism. When you are a people with no nation and therefore no army you can’t invade other territories.
Tenants of Christianity and Islam are the conversion of non-believers.
Judaism has no such evangelism.
Simple. They denied Jesus and lost favor.
Before Judaism there was a lot of polytheistic religions.
Judaism never really got into converting others. But it was Christian’s favorite thing, to the point where they just jammed in random existing holidays so converts could keep celebrating their traditions.
Christianity did the legwork to get people open to a single Abrahmic god, but they were dicks once they got into the majority. Like Walmart moving and selling at a loss till competition was gone and jacking up the price.
For people raised Christian, Islam wasn’t a big jump. And early Muslim society produced an absolute shit ton of science and was way less extreme than the people who make it into modern news, but so are the vast majority of modern Muslims.
Tldr:
There was never a huge push to convert to Judaism, unlike the following Abrahamic religions.
The difference between the three is basically:
Judaism: loads of prophets, Jesus can be recognized as one of them. Messiah still to come
Christianity: no prophets really, just followers of Jesus the Messiah, who will return. (Some think he’s literally god).
Islam: loads of prophets, Jesus was one of the biggest, then Mohammad, and next someone else. Messiah still to come
Switching doesn’t require much changes of belief.
