Well lets put it this way, there are 14 million Jews Approx.
There are 2 billion Christians Approx.
There are 1.7 billion Muslims Approx.
At one time we were all Jews.. So 14 million to 2 billions is pennies,
in every case of 10 people there 4/10 that dont believe.
So, at one time i would say they were ALOT of Jews, When Jesus came Those people were so stuck on their faith that they didnt care what anyone said, they never believe what anyone said.
But their friends might have believe. But not everyone will.
So they were 100 Jews, when Jesus came, 85 of them believed and went on to believe in Jesus, but the other 15 stayed STRONG about their faith " Although they mistakenly did it " and so on those 15, had families , and their kids had kids, all these generations of kids believed what those original 15 did was right. They dont question their parents beliefs.
So those 15 turned into 14 million as of today (15 is a figuratively speaking number)
Those 14 million CANT believe Jesus is a messiah no matter what Anyone or any book says, They were BORN believing he is not, BUT what they dont know is that there ancestors were part of the wrong 15 people who decided not to believe.
Now their neighbors might be CHRISTIANS, but they have no idea that those christians ancestors were once FRIENDS with those original 15 jews, and was part of the 85 people who WERE JEWS then believed....
--This is not the case for just JEWS, but for everything in life
Where 2000 years ago or 20 years ago, people have to say, "Well, WHO KNOWS WHAT COULD OF REALLY HAPPENED"
Maybe i am wrong, but, MY theory sounds legit, because, All should have converted if they believed in their own books, and IF SOME PEOPLE DIDNT convert, its because they chose not to believe, and they dont know that what they did caused millions in the Future (today) to believe...
Hope you get the point
