Refining Limbs Into Menorah
במדרש מנורה של פרקים כו' לטובתך נתתי לך השבת
In the Midrash, regarding the menorah of sections and the like: "For your own benefit I have given you the Shabbos."
The Sfas Emes opens with a Midrash teaching that Hashem gave Bnei Yisrael the Shabbos as a gift for their own benefit. He links this to the idea of preparing now for a future reward.
דאיתא היום לעשותם למחר לקבל שכרן
For it is taught: "Today to do them" (Devarim 7:11) — in this world to perform the mitzvos — "and tomorrow to receive their reward," in the World to Come.
The pasuk distinguishes between now and later: this world is the place to perform the mitzvos, while the World to Come is where their reward is collected.
הענין הוא כי עוה"ז דומה לפרוזדור בפני עוה"ב
The matter is this: that this world is comparable to an antechamber before the World to Come (Avos 4:16).
He cites the well-known teaching of Chazal that this world is merely an antechamber, a corridor leading into the great hall of the World to Come.
פי' ע"י המצות בעוה"ז מתקנים האיברים להיות כלי מוכן להשראת הקדושה דלעתיד עין לא ראתה כו' יעשה למחכה
The explanation is that by means of the mitzvos in this world a person refines his limbs so that they become a vessel prepared for the resting of the kedushah of the future, of which it is said, "No eye has seen, [O Hashem, besides You, what] He will do for the one who waits for Him" (Yeshayahu 64:3).
Performing mitzvos here is not just earning credit; it actively refines a person's physical limbs, turning them into a vessel fit to receive the future kedushah that no eye has ever seen.
פי' שציור האדם יש בו דברים נפלאים אבל בעוה"ז הוא נסתר וע"ז כ' מה רב ט' אשר צפנת כו'
The explanation is that the form of man contains wondrous things, but in this world they are concealed, and concerning this it is written, "How abundant is Your goodness that You have hidden away" (Tehillim 31:20).
The human form holds wondrous, lofty potential that remains hidden in this world. The pasuk in Tehillim refers to this concealed goodness that Hashem has stored away.
ולכן נק' המצות נרות שהאיברים נעשים כלים בכח המצות וכשנתקן כל האדם להיות מנורה שלימה אז לעתיד יהי' לך ה' לאור כו'
Therefore the mitzvos are called "candles," for the limbs are made into vessels through the power of the mitzvos; and when the entire person is refined to become a complete menorah, then in the future, "Hashem will be for you an everlasting light" (Yeshayahu 60:19).
Mitzvos are called "candles" because they transform the limbs into vessels that can hold light. Once the whole person becomes a complete menorah, he will radiate Hashem's everlasting light in the future.
ולכן בש"ק שהוא מעין עוה"ב הוא ג"כ הארה יתירה כמ"ש חז"ל אין דומה מאור פניו של אדם בשבת למ"פ בחול
And therefore on the holy Shabbos, which is a foretaste of the World to Come, there is likewise an additional illumination, as Chazal said, "The radiance of a person's face on Shabbos is not comparable to the radiance of his face during the week" (Bereishis Rabbah 11:2).
Shabbos is a taste of the World to Come, so it carries an extra measure of this hidden illumination, which is why Chazal say a person's face shines more on Shabbos than during the week.
ובאמת בריאת האדם הכל ענין א' בזה ובבא כמ"ש וייצר ב' יצירות
And in truth the creation of man is entirely one matter, in this world and in the World to Come, as it is written "vayiytzer" with two yuds, alluding to two formations (Berachos 61a).
The creation of man was always a single, unified design spanning both worlds. The double yud in "vayiytzer" hints at two formations built into man from the start.
יצירה בעוה"ז בעשי' כמ"ש היום לעשותם ובעוה"ב הפנימיות וזה נק' קיבול שכר:
There is a formation in this world, in deed, as it is written "Today to do them" (Devarim 7:11); and there is the inner formation in the World to Come, and this is called the receiving of the reward.
One formation is in this world, expressed through action and deed; the other is the inner, hidden formation revealed in the World to Come, which is the receiving of reward.
Summary: The Sfas Emes explains that Shabbos was given to Bnei Yisrael as a gift, embodying the principle that this world is the antechamber where we perform mitzvos and the World to Come is where their reward is received. Performing mitzvos does more than earn merit; it refines a person's limbs into vessels fit to hold the future kedushah, which is why the mitzvos are called "candles" and the fully refined person becomes a complete menorah radiating Hashem's everlasting light. Much of man's wondrous potential lies concealed in this world, as the pasuk says of the goodness Hashem has hidden away. Shabbos, being a foretaste of the World to Come, already carries an extra measure of that hidden illumination, so that a person's face shines more brightly on Shabbos. Ultimately the creation of man is one unified design across both worlds, hinted in the double yud of "vayiytzer": an outer formation of deed in this world and an inner formation revealed as reward in Olam Haba.
