In a letter dated the 17th of Av 5722, a woman asked the Rebbe why is it that Jews are not commanded to convince Non-Jews to convert to Judaism.
The Rebbe responded:
“In response to your question, why the Jews don’t have to encourage the Non-Jews to convert –
[The reason is:] Each person has a specific mission in this world, and a specific set of directives how to behave according to the Torah of G-d: The Jews have to fulfill the 613 commandments, and the Non-Jews – the Seven Noahide Laws with all their details.
There is only an extremely small number of souls which are destined to convert.”
(From this week’s Lahak Kuntres)
Two years earlier, in in a Yechidus to a group of Hillel students, on the 8th of Adar 5720, the Rebbe was asked:
Question: What is the Jewish attitude towards conversion?
Rebbe: Never were Torah Jews enthused about conversion. A Jew should be a good Jew and a gentile should be a good gentile. There is for us enough to do in just seeing that Jews are good Jews. Every limb of a body has its particular function. Each limb has its activity to which it is fitted. Likewise, every created thing has its particular function. The Jew has his and the gentile has his.
