The Tears of a Child

18:1 | וירא אליו ה׳ / And G-d revealed Himself to him [Abraham]...

When Rabbi Sholom DovBer of Lubavitch was a child of four or five, he entered the room of his grandfather, Rabbi Menachem Mendel, and burst into tears. His teacher in cheder had taught the verse “And G-d revealed himself to Abraham...” “Why,” wept the child, “does not G-d show Himself to me?!”

Rabbi Menachem Mendel replied: “When a Jew, a tzaddik,1 realizes at the age of 99 that he must circumcise himself, that he must continue to perfect himself, he is worthy that G-d should reveal Himself to him.”
