How Did Rav Kook Base His Decision that We Must Love Non-Religious Jews?
How can the Torah command us to love every single Jew? How can the Torah command us to feel an emotion? Apparently we're referring to a mindset that is achievable, but how? Rav Kook was famous for his love of each and every Jew, even those far from Torah. This approach was very controversial in his time, but has since been almost unanimously accepted, even within haredi circles. What is the halachic and philosophic explanation and basis, and how can we practically acquire this difficult trait?
