Providing a Solid Torah Education is one of the many Responsibilities of Jewish Parents.
Not only does it give a Child a happier life, but it also assures Jewish Continuity.
Here is One Site that talks about the importance of a Jewish Education
I found a site that shows the statistics of Jewish Continuity:
The Single Comonality We have among Jews is that Our Mother is Jewish or We converted to Judaism. The Resulting Commonality is that we received the Torah at Mount Sinai – the only time in history when G-d spoke to an entire nation of people to give them The Torah (No Other Religion Claims This). The Only real way to give a child a lasting Jewish identity is through teaching them and observing the Torah with them. Observe the Shabbat, Eating Kosher, Discuss Torah Topics, Light Shabbat Candles, Community Prayer, etc. In the National Jewish Population Survey – supports this statistically – citing that over 94% of Yeshiva Othodox Jews marry Jewish. Their commonality is that they observe Torah and Mitzvot.
Here are the statistics.
