This pasuk implies that Bircas Ha’mazon is not merely a formal offering of gratitude for the meal which we have eaten. Rather, it proclaims our acknowledgment that Hashem is the source of all things. Indeed, we even submit our thanks to Hashem for providing us with our land. This seems enigmatic. Imagine being invited to someone’s home for dinner and, after the meal, thanking the host for the use of his furniture and home during the course of the meal. This expression of gratitude is undoubtedly excessive. Why, then, is it necessary to specifically mention the land during Bircas Ha’Mazon?
Horav B.Z. Baruk, z.l., offers the following analogy in response. A person who was hunger stricken and thirsty is walking in the desert, completely exposed to the elements. Suddenly, a plane lands as if from nowhere. A beautifully furnished home complete with a table laden with various delicacies ready for his consumption appears before him. Obviously, in such a situation, the individual’s gratitude would extend beyond a simple acknowledgment of the delicious meal. He would indicate his appreciation for everything. Similarly, we should acknowledge that every meal we enjoy is a brand new creation, resulting from Hashem’s beneficence. We have fallen victim to the sin of complacency by taking everything for granted. Regretfully, we reflect upon Hashem’s favors only when we are denied them. Increasing our awareness would neutralize this apathetic attitude.
