There is a statement that is found numerous times in the Talmud. It says that from the time the Beit Hamikdash was destroyed, אין ל קדוש ברוך הוא בעולמו אלא ארבע אמות של הלכה, that Hashem has nothing in this world except for the four cubits of Halacha.
This statement is interpreted in different ways but its main meaning is as follows: The act that seems to give G-d the most satisfaction in this world is not merely the study of Torah. Delving into Chumash, Midrash, Mishna, and Tanach, are certainly worthy ventures. However, when one takes his study a step deeper, by investigating HOW we arrive at the Halacha by way of studying the Gemara and Poskim, he is attaching himself more deeply to Hashem’s very essence.
The Ramchal says that the study of Talmud, is an exercise in the pursuit of truth. The four cubits of Halacha reflect a desire and willingness for an individual to connect to the knowledge of Hashem’s will. This gives Hashem the most satisfaction.
