That is a serious misconception as well as a gross over-statement. Jews have always believed in Jesus. In fact, in the beginning, it was only Jews who believed in him, and today, there are probably more Jewish believers in Jesus than ever before.
Although you may not be aware of this (I certainly wasn’t for the first sixteen years of my life), it is common knowledge to both Jewish and Christian historians that all of Jesus’ original followers were Jews, and within a few years after his death and resurrection, thousands of Jews believed in him. At first the question was, “Can you be a Gentile and believe in Jesus?” That’s how Jewish this whole thing was! (Read Acts 15 for more information.)
Since then, in every generation there has been a faithful remnant of Jews who have followed Jesus the Messiah, numbering from the thousands into the tens of thousands, and they have maintained their faith in spite of often difficult consequences. Right now, there are as many as 150,000 to 200,000 Jewish believers in Jesus worldwide (this is probably a conservative estimate), including American Jews, Russian Jews, South American Jews, and Israeli Jews. Many of them are highly educated, and some are ordained rabbis. Jews do believe in Jesus, and their numbers are growing by leaps and bounds.
