A functioning human society relies heavily on spiritual direction and clear moral boundaries. When guiding leadership and voices of correction disappear, human nature tends to dismantle its own frameworks, causing society to sink into anarchy and destructive behavior. This necessary guidance usually comes in the form of prophecy or the active presence of a visionary whose role is to correct the people [אבן עזרא]. Other perspectives view this guidance more broadly as having comprehensive foresight and planning for the future [רלב״ג, ביאור שטיינזלץ].
The primary approach among commentators is that prophecy serves as the ultimate moral and social compass. When people disrespect their prophets, causing this divine communication to depart, the immediate result is the breaking of social boundaries and a descent into corruption [רש״י]. Without this compass, people become wild and unbridled [מלבי״ם, ביאור שטיינזלץ]. Morality is essentially suspended [מצודת ציון], leaving the nation exposed and defenseless against its enemies [עמנואל הרומי], which can ultimately lead to exile [אבן עזרא].
This breakdown occurs because people naturally differ greatly in their characters and traits. Without a unifying law and singular leadership to bind them together, society inevitably becomes confused and collapses. Left entirely to its own devices and desires, human nature is highly destructive [רלב״ג, עמנואל הרומי]. One might wonder why a living prophetic vision is necessary when the written Torah is readily available for anyone to read and follow. However, face-to-face correction from a wise prophet carries a much deeper and more profound impact than independent reading. Without the living, breathing voice of a prophet, the masses are prone to disconnect from serving God, thereby losing His divine providence and the protective shield that hovers over them [אלשיך].
Yet, even in the absence of open prophetic leadership, there remains a paved road ensuring protection, stability, and joy. Following the close of the prophetic era, the Torah itself takes the place of the living vision, granting the people all the direction they need [מלבי״ם]. It establishes the essential boundaries, and its illuminating wisdom returns a person to the proper path, preventing the pursuit of unworthy desires [רלב״ג, מצודת דוד].
While the general public might easily deteriorate without a prophet, the rare individual who manages to internalize moral discipline and stay loyal to the Torah—even without a guiding vision—achieves immense joy [אלשיך]. This state of happiness simply means that life is profoundly good for such a person [ביאור שטיינזלץ], and others will ultimately praise them for their abundant fortune [אבן עזרא]. Ultimately, safeguarding these laws grants a person complete happiness, protecting them from suffering in this world and guaranteeing eternal goodness in the world to come [עמנואל הרומי].
