<div dir="ltr">I'm not certain that it has any valid halachic connection to gerus, but the following story may have some value for understanding the concept of kabbalas ol mitzvos:<br><br>R Aryeh Rottman, Dean of the American-chareidi "Yeshiva Mercaz HaTorah" in Israel, told me that when he served as a Rav in Miami Beach, FL, he slowly brought a middle aged couple back to Torah observance, with just one hitch. The husband told R Rottman that he refused to accept life threatenting illness as the drawing line for violating shabbos in connection with refuah. "If my wife has a medical problem, or is in any pain, I'm driving her to the doctor, Rabbi" he said. R Rottman wanted to know if this man could be considered a "Shomer Shabbos" for halachic purposes involving kashrus, etc. R Rottman asked R Aharon Kotler if the man was considered a shomer shabbos. R Kotler said it was apparent that this man had in mind to accept the mitvos and halachos of shmiras shabbos, but could just not fathom that G-d would want him to forgo seeing a doctor unless the situation was life-threatening. Therefore, the man's shmiras shabbos is acceptable enough to consider him a "shomer shabbos," even though he denied a halacha that he knew was in the Torah. The man was not considered a Yisrael Mumar or a "mchalel shabbos" individual. (Obviously the man would still be mchalel shabbos, at least bshogeg,
whenever he drove on shabbos, as am I if I forget the halachos of borer).<br></div>
