The Biblical and Rabbinical writings abound with references to the significance, need, and redeeming qualities of this mitzvah. For Gemilut Chassadim is the very foundation-stone and pillar of the universe. Without social justice and morality, the righteousness and compassion signified by the concept of Gemilut Chassadim, there can be no society; humanity cannot exist.
Our Sages note that the beginning, middle, and end of the Torah deal with Gemilut Chassadim. Thus whoever says that he cares for nothing but Torah, to the exclusion of Gemilut Chassadim, he has not even Torah, as it is written: "Learn them and be careful to perform them" (Deuteronomy 5:1). For the study of Torah is meaningful only when it leads to an actual observance of the mitzvot. By the same token, "an am ha'aretz, a person who knows not the Torah, cannot be a chassid (a pious person)," i.e., one who performs chessed. When ignorant of the teachings of the Torah one cannot possibly act in the manner that the Torah requires. It is the Torah that determines which deeds are regarded as acts of Gemilut Chassadim, and lends them their sacred character of being a mitzvah.
Torah and Gemilut Chassadim are inseparable one from another. That is why we find them usually coupled in the teachings of the Sages. Thus it was taught: "If Israel would consider the words of the Torah that was given to them, no nation or kingdom would have dominion over them. And what does (the Torah) say to them? Take upon you the yoke of the Kingdom of Heaven to excel one another in the fear of Heaven, and to conduct yourselves, one to another, with acts of loving-kindness."
