This is a conceptual, Halachic, moral and current question. A number of “historic accidents” have brought people to abandon their Jewish roots. Sometimes this took place of their own free will but most of them had to act this way unwillingly, beginning with the Inquisition, through anti-Semitism, Communism and the Holocaust, all of which attempted to displace the Jews from their Judaism and from their brethren. However, in spite of everything, Israel is not alone, and God, who appears as the Angel of History, brings our brethren back home, back to their family.Very few think about the future of the Jewish people. Many deal with the past, with history, but only a few give thought to the future: What can we do to prevent the loss of the Jewish people in the Diaspora and perhaps even in Israel? One cannot speak about the Jewish people only in terms of numbers and statistics. As of now, the Jewish people are showing signs of spiritual and demographic weakening – the Holocaust, assimilation, loss of identity, estrangement form Judaism and a contraction in the number of Jews in the world. Despite that, there are recognizable signs of spiritual awakening, people returning to religion, spiritual searching and searching for their roots. Therefore, it seems that despite all the efforts in the realm of education in order to bring people closer to religion, through an effort of strengthening the people from within, we must go and search out our lost brethren, flesh of our flesh, in order to fully strengthen the Jewish people. Rabbi Tzadok of Lublin taught us that when we speak about the ingathering of the exiles and the return of lost Jews, we do not mean those who are certainly Jewish but also those who aren’t Jews according to Halachah, or don’t even know that they are of “Jewish seed” in actuality and spiritually.
