G-d revealed Himself to Avram...why not us?

Lubavitcher Rebbe, Parshas Vayera 5752

"Avram was ninety-nine years old, and God revealed Himself to Avram..." (Parshas Vayera 17:3)

This produces a lesson for every individual. When he reads that G-d revealed Himself "to him," he must realize that "to him" does not mean only to Avraham, but "to him," to his own self. Since he is a descendant of Avraham and has entered into "the covenant of Avraham" through circumcision, G-d reveals Himself to him. This should arouse in him a desire to actually see that revelation, a desire which can be so powerful that it motivates him to cry.

Similarly, this desire should be powerful enough to motivate every individual to carry out his service in causing G-dliness to permeate every aspect of his being and all dimensions of his portion in the world at large. In this manner, he will make himself a vessel worthy of Divine revelation and indeed, cause that revelation to permeate the entire world, making the world a dwelling for Him.
