Ba'al Shem Tov, Vaetchanan 17/בעל שם טוב על התורה·ואתחנן י״ז

1Once, the Baal Shem Tov became so despondent that he thought that he surely had no portion in the world-to-come. There was nothing he could do to encourage himself, until he declared: “I love G‑d even without the world-to-come!”Sichos HaRan 48
