A profound relationship exists between fulfilling God's directives, acquiring a deep sense of awe, and securing both personal and generational longevity. Awe of God is not merely a fleeting emotion; it is the ultimate purpose of human creation and the very foundation upon which the entire Torah rests [ביאור יש"ר].
A fundamental question arises regarding the exact dynamic between observing the Commandments and fearing God. While one perspective suggests that awe serves as the initial motivation for fulfilling God's will, the primary approach among commentators is quite the opposite. Awe is not the prerequisite, but rather the profound reward and direct result of performing the Commandments [רמב״ן, הטור הארוך, ביאור יש"ר]. Through the active practice of these directives, a person ascends to a high spiritual level where true awe is achieved.
This elevated state of awe is understood in several ways. It can stem from the humbling recognition that God is the ultimate master of the earth, while humans are merely temporary residents in His world [ספורנו]. Furthermore, this is not a basic fear of punishment, but a majestic awe of God's greatness. Grasping this greatness inspires a person to joyfully pursue His Commandments without any expectation of material compensation [מלבי״ם]. There is also a spiritual momentum at play; fulfilling one Commandment naturally leads to another. This positive cycle provides a person with heavenly assistance and protection against negative impulses, ensuring they remain on the right path [העמק דבר, מלבי״ם].
This spiritual dedication extends far beyond the individual, creating a chain of unbroken generational continuity. The divine intention is for all future generations to follow one after another in faithful observance [רלב״ג]. Even those descendants who did not personally witness the great biblical miracles will naturally absorb a deep awe of heaven simply by observing the unwavering dedication of their parents [ספורנו, העמק דבר]. This dynamic serves as a guarantee that future generations will not face spiritual decline, but will instead stand equal to their ancestors in their greatness and knowledge of God [חתם סופר].
Regarding the promise of longevity, commentators draw a distinction between different realms of existence. The blessing of daily life refers to this current world, where a person receives divine assistance to observe the Torah without earthly distractions or interferences [העמק דבר]. Conversely, the promise of a prolonged existence points toward eternal life in the World to Come, an existence that is entirely enduring [ספורנו, רבנו בחיי]. Other scholars take a more literal approach, viewing this as a promise for a long physical life in the Land of Israel, which is God's own inheritance [רמב״ן, הטור הארוך], as well as a guarantee for the historical survival of the Jewish people as a whole [ביאור שטיינזלץ]. Ultimately, the physical rewards promised in this world can be compared to the sweets given to a young child to encourage them to learn. The true reward is the act of the Commandment itself. God grants a long life simply to provide a person with more time and opportunity to fulfill even more Commandments [מלבי״ם].
