The implications of this passage apply, as the Torah says, "to you and your posterity." We may become strangers to Judaism, wandering on distant paths, far from Torah and the Jewish spirit. We may become spiritually defective, Jewishly impure, insensitive to the values and beauties of our faith because we live by ideals and codes alien to Judaism. But we are not doomed to living apart from Judaism. We are never denied the opportunity of purifying ourselves, correcting deficiencies, reestablishing the bonds connecting us with G-d, Torah, and Israel.
Obviously distant paths and impurity are not new to Jewish history. But Israel survived the centuries because Jews returned from their journeys, to maintain the integrity of Torah and Israel.
