When the world will reach its ultimate state with the coming of Moshiach, this concept will be clear. It will be obvious to all that the rich, the smart and the strong are not praiseworthy for the gifts they have been granted. Rather the fulfillment of Hashem's will, regardless of the circumstances, is what defines greatness. Therefore, Hashem will be able to restore the moon to its original light, for man will not stumble and think that equal ability means equal greatness. Thus, אור הַלְּבָנָה כְּאוֹר הַחַמָּה the moon will be restored to its initial light at a time when the world will see clearly that the sun and the moon are indeed equal, for they are fulfilling the roles Hashem gave them.
(חתם סופר פר' בראשית ד"ה את שני המאורות הגדולים)
This is a crucial concept to internalize in order to overcome our basic animal instincts. For only if we have a crystal-clear awareness of our constant ability and obligation to be our best selves in any situation, can we consistently strengthen our neshamos over our guf. We are only obliged to follow the course upon which Hashem leads us. By faithfully following this path, through consistently acting according to our higher values as opposed to our natural desires, we will bring closer the time when אור הַלְּבָנָה יִהְיֶה כְּאוֹר הַחַמָּה. Amen.
