In this shiur, delivered in the Feder home in Lawrence, Rav Burg discusses (based on a Torah from the Nesivos Shalom and from the Kedushas Levi) the inner connection between the Omer and Bris Milah and why we don't make a shehecheyanu on the Mitzvah of the Omer. While seeing Hashem in the miraculous can jump start a relationship we have only learned about Hashem, we have not yet built a relationship with Hashem. When we find Hashem in nature, we shift our relationship from one of action to one of presence. On Shavuos, through the Korban Todah we have the best of both worlds.
